Is surface profile of the substrate pertinent for an effective adhesion of the electrodeposit? Does it only improve the aesthetics or also influence the functional properties? What are the options? Do treatment methods vary with substrates?


This short paper answers these questions and offers a synopsis of those processes. The processes are blasting, mechanical polishing, vibratory bowl movement, bright dip, chemical polishing, and electropolishing. 



Industry uses abrasive or sand and glass bead blasting methods to clean and change the surface profile of the substrates before plating. Silica, aluminum oxide, and glass beads are the often-used media at various grit sizes. Machines and manual booths (closed) are used to execute these methods. This is an age-old technique. It is a simple process, but leaves impregnated particles on the surface and, if not properly removed, might affect the next processes (cleaning and plating).



On mechanical polishing and similar category falls polishing, buffing, lapping, and grinding. Unlike buffing, polishing removes the metal surface. Lapping and grinding change the surface significantly. Industry uses muslin, canvas, leather, etc. as polishing wheel materials. Muslin is most extensively used as a buffing wheel. These mechanical processes are used to improve the aesthetic appeal of the substrates. As further pre-cleaning is involved before polishing, the polished and buffed substrates reduce the load on plating line’s pretreatment processes.


Vibratory Bowl Movement

Deburring and improving Ra value of metals are the primary applications of the vibratory bowl movement method. We can use this method on several metals and substrates (before plating) like copper and beryllium alloys, stainless steel alloys, low and high carbon steel alloys, nickel and titanium alloys, and several others. Size and shape of the substrates, media, chemicals used during the bowl movement, speed of the movement and time control the resultant finish. Unlike mechanical polishing and blasting, the process doesn’t leave residues on the substrates.  


Bright Dip

As the name implies, this process improves the brightness of the substrate. It improves the surface profile and helps aid oxide layer removal. This is an immersion process mostly using an acidic solution for 5 seconds to 5 minutes. Commonly used substrates are ferrous, copper, beryllium, aluminum, stainless steel, nickel, and Monel alloys. Zirconium, titanium and silver metals can also be bright dipped. These processes cost less, and the solution life is short.


Chemical Polishing

Chemical polishing process is like bright dip, but removes more substrate material. Many copper alloys and a few ferrous alloys can be chemically polished. Some chemicals are toxic and need good air ventilation for a friendly environment, health and safety practices.



Electropolishing is an anodic process. Electrolysis selectively removes micro – peaks of the substrate metal. This process offers superior passivation and corrosion resistance properties on 300 and 400 series stainless steel alloys. The passivation properties got from electropolishing are better than nitric acid and citric acid passivation processes. Common metals electropolished are 300 and 400 series stainless alloys. Other alloys are Al, Cu, Monel, nickel, silver, zinc, tin, Co, Ti, and low and high carbon alloys.


Electroplating Surface Profile


These methods can alter the surface profile of the substrate metal before electroplating. Cost, chemical hazard, and awareness distinguish the choice and application of these methods. Each method has advantages and disadvantages.

Blasting is the easiest. Vibratory bowl movement and electropolishing methods offer the best aesthetics and functional properties after the deposition process.


We can enhance the deposit brightness, leveling characteristic, adhesion and surface profile Ra values using any of these processes.

The true plating capability refers to a process which performs as almost as expected. It executes with lesser labour, zero downtime, greater process control and with exceptional physical characteristics. Though it might appear simple, most job and captive plating shops seldom meet an effective realization of the said ability.



Most processes have unique challenges. Cyanide and electroless electrolytes, precious metal plating like gold and silver, aluminum anodizing and stainless steel electropolishing need exclusive tactics. Cost metrics and process complexity varies within these processes.


An important holdup most stumble is accepting the status quo. Process failures, downtime, delays, etc. are perceived as a norm. As it occurred yesterday and transpires with others too!

Also, people with emotion become agnostic to methods, tools, concepts, and approaches. While, data science and artificial intelligence sans use of emotion.

This short paper aims to show a path toward a true electroplating capability.


Here is a simple infographic of vital elements to attain this goal:

True Electroplating


As shown in this graphic, our intent is at the core of our actions! Begin with intent to achieve infinite results.


We need knowledge and creativity with intent. The staff must have a comprehensive training on electroplating, lean, statistical process control, and total quality management. A good understanding of periodic table and electromotive force (emf) potential is mandatory. A process control is contingent on sampling and analytical techniques, and database integration with spontaneous communication and reaction.


Consider using 6 process development and control (PDC) tools as recommended by Advint’s earlier blog as an alternative to 7 quality control (QC) tools.


Plant Design and Automation

On no occasion reckon to aid a true electroplating feat with an inextricable and poor electroplating equipment design.


A nimble design with a correct choice of electrolyte chemistry, materials selection, engineering capabilities, rectifier controls and calculations such as ampere hour control, serial communication are indispensable.


Choose IGBT rectifiers for nickel, copper, silver, zinc and chromium plating applications. IGBT will be suitable for most anodizing applications, but sometimes a SCR rectifier or a half wave SCR rectifier will be essential.


Plating equipment and the manufacturer play a significant role in the plan of a new line. The project managers of most manufacturers do not have industrial plating experience. Under these situations, planning on processing, development tools, creativity and method become imperative.


True Electroplating Rewards

When a process performs, employee and customer satisfactions are at its zenith. You get to eat your competitor’s dinner.

A recently published paper by a senior staff on a leading American magazine was unclear about the electroplating terms, like covering and throwing powers. Many times, we see vague interpretation and wrong distinction on these terms.


Advint’s online electroplating training and E-book offers right definition, explanation of identical terms and concepts. So, I’ll abstain from offering an elucidation here and write on the effects and recommendations.


The supplementary purpose of this paper is to emphasize the importance of correct interpretation of underlying electrolysis mechanism, terms, concepts of electrochemistry and electroplating fundamentals.


The confusion on these terms occurs when one draws a literary meaning on these words, reads leading technical magazines and science journals, and listens to veterans in this field.


Dr. Samuel Glasstone’s An Introduction to Electrochemistry delivers the clearest definition of throwing power of an electrodeposition process.

To correctly understand the terms, deeply observe acid chloride zinc or Watts nickel plating and cyanide copper or cyanide silver plating processes. Careful analysis of these electrolytes using a Hull cell will make clearness of these terms.


Handbooks and electroplating books frequently cannot document and analyze all developments, and now and then it misconstrues the depth of progress in the metal finishing field.


Confidentiality and hidden knowledge within the industry is the reason for such limitations. This limits awareness of all electrolyte properties and their formulations options with benefits. Many large organization’s operating procedures and practices also deter the best ability of a process.

We recommend you to question, test and re-consider critical attributes and formulations, including the references of Advint’s e-book guide to get a model electroplating routine.


Why is it imperative to comprehend properly?

Choosing a suitable electrolyte and maintaining the concentration of anions and organics will enable us to:

  1. improve product quality
  2. improve deposition thickness with due consideration for product geometry
  3. meet functional and customer criterions
  4. improve process control
  5. reduce cost associated with rework and under or over thicknesses
  6. minimize or eliminate problem solving time
  7. correctly comprehend fundamental electrolysis mechanisms

How can you learn the correct terms?

Advint’s virtual course E-book syllabus covers relevant electroplating terms and concepts.

We recommend referring authentic resources, test yourself by analyzing electrolysis and deposition mechanisms on various electrolyte formulations and metal deposits.


To the Point

In this short paper, we discussed why right construal of a plating term is important. We reviewed how to access the pertinent information and the reasons for confusions. A diligent comprehension of the terms will help advance the metal finishing capability to what it’s worth.

Surface profile of the substrate, specifically surface activity and its receptivity to accept electroplating deposit, spontaneously determines the morphology.

A deposit with good morphology will possess an adherent deposit. There is a myth and inadequate science work related to surface profile and adhesion. A few sectors do well with improving surface activity, and a sector is vulnerable. This short paper intends to shine light, dissipate a myth, and suggest improvements with supporting information.


Cleaning & Activation

It is a normal practice to blast a metal surface to improve cleanliness. This approach predates the 60s, when cleaner science had made minimal progress. Over the years proprietary plating supply houses like Atotech, MacDermid Enthone and Coventya had conducted extensive research and offer an array of cleaning products. We released a short paper explaining the importance of cleaning on April 1, 2019.


In the absence of an effective cleaning process, blasting the surface is pertinent. It is an important treatment method on applications where we require higher Ra values or unique aesthetic appeal. Rather, if one blasts a surface merely to improve adhesion, then it is time to debunk the myth! Now, I’ll back up the purpose with facts and information.


To get an adherent deposit the metal surface must be clean, active and receive nucleation (form a unimolecular layer) within the first 10 or 20 seconds regardless of the current distribution pattern. A spontaneous and uniform deposit formation is important. The critical nucleation time varies between substrates and the deposit element’s electrode potential.

A truly active surface allows effective nucleation.

A poor nucleation layer will disrupt crystal growth and cause re-nucleation of the crystals. This disruption leads to deposit non-coherence and inconsistency in physical characteristics, resulting in premature product failure. Impregnated blasted media is very difficult to obliterate the surface and in most cases leaves a residue, hinders nucleation or continuity and uniformity of the deposit. An electropolished surface address this concern and enables epitaxial or pseudomorphic growth when and where applicable. This surface possesses very low Ra values, are active and free from foreign materials. If it drives you to get the most adherent deposit, electropolished surface is one of the best means to achieve this endeavor.


electropolishing electroplating surface profile


Surface Profile & Adhesion

A truly active metal surface can form a thick intermetallic layer and develop a single domain deposit morphology (columnar structure) through the process. A single domain columnar structure deposit will possess a distinct grain boundary.


This mechanism is not independent of process control. The author of this paper had conducted extensive research over a decade on this matter, and so did a few other scientists from our society during the 80s and till now. A deposit with an intermetallic layer forms the most adherent deposit. In order for a non-electropolished surface to form an intermetallic layer, it must possess an active surface. We know that an electropolished surface possesses lower Ra value, but we require more controlled studies to validate the relationship between the surface profile and adhesion. On this subject, good surface profile implies a clean, smooth and active surface.


Morphology & Physical Characteristics

Most adherent deposits possess good morphology. A deposit with an intermetallic layer and undisrupted columnar structure will have greater than 20% improvement in physical characteristics such as hardness, tribology, and corrosion resistance properties. 



Blasting is a valuable pretreatment method, but an ambitious applicant must recognize that residue left on the surface affects the deposit characteristics, and it is not a certain choice in pursuit of an adherent deposit. Electropolishing is not practical on many applications. Exceptional cleaning and activation are viable and important.


Accomplishing an intermetallic layer on all applications is an unreasonable expectation, but a clairvoyance can set that as an aim. This aim is akin to lean’s one-piece flow and six-sigma.

In short, be mindful of the relationship between activation, morphology and physical characteristics.



Material scientists and electrochemists now and then use different terminologies when referring to the same concept. Some terms used in this paper are no exception.

I used material scientist as a substitute for metallurgist. The global technical community replaced the term metallurgy with physical characteristics in 2010.

This paper is about the Hawthorne effect, the obvious but not so obvious effects, and the necessity.


Electroplating, anodizing, electro-polishing and complex processes such as plating on plastics require leadership drive to advance operations and engineering performance, and sustain on the growth.


An exemplary leader sets the expectation, creates necessity, delegates responsibility and confirms accountability without micromanaging the trivial effects.

We can set a clear expectation on variables such as electrochemical variables, process yield, product flow, inventory management, employee and executive management engagement.


Hawthorne Effect

The Hawthorne effect is the improvement detected because of a noticeable observation of the process. In reality, it does not confine the effect to a process, rather it encompasses to an employee performance. In both cases, it is a top-down approach, but ends with a continuous observation from all levels. When a leader sets the expectation, consistently follows up, align the goals with his or her actions, and supports their team to succeed, the team would achieve operational excellence in the long term. Observation and commitment to improvement must include all critical key performance indicators (KPI’s).


Obvious but not so Obvious

In retrospection, every challenge we overcame and the opportunities for improvement would become obvious to us. But this is late, as by this time we would have non-conformances, cost infliction and customer dissatisfactions. It is prudent to detect the obvious challenges and opportunities in real time. Earlier the opportunities were present, but hidden. We miss as it is not obvious!


If I did not communicate, think about the current COVID-19 pandemic. The issue originated in December 2019 and peaked in China during mid-February 2020. If the issue was apparent to global leaders and commoners around January, would the consequences be the same?

Revealing the hidden challenges in actual time is the heart of your effort in improving effectiveness.


How to expose these challenges? What prevents us from reading between the lines? The answer is not simple. This would be contingent on the leader’s emotional intelligence, knowledge of the subject and availability of visual data and information on real time.


Electroplating anodizing process line


Yield Shadows Necessity

We can achieve metal finishing processes and business effectiveness by focusing first on necessity. One must focus on the necessity to perform, collaborate, and on satisfaction (employee and customer). Yield will shadow the necessity–big or small; it is for you to choose! Clear responsibility and unambiguous accountability are the means to achieve necessity.


An Idea in Brief

Electroplating and other metal finishing processes are complex, as we all know. Market and customers are demanding. Contingencies like the COVID-19 pandemic will subject job shops and captive platers to hardship.

At these and regular times, being conscientious of the process variables, exposing the hidden opportunities on real time, and starting with a focus on necessity are three important steps to achieve effectiveness in the manufacturing operation.

Creating suspense is the best way to improve customer dissatisfaction. Unpredictability is a no lesser means towards employee dissatisfaction. Dependence on a plating troubleshooting guide helps these two effects. 

Why this topic?

Many Advint’s short paper readers know I consistently write on various electroplating topics for the last several months. I am also meticulously writing a course book covering all subjects related to plating. While working on these I noticed many books and articles written by consultants and experts in the past concentrated more than required on the troubleshooting guide. My mind questioned the need. And, I was musing rather shouldn’t the emphasis be on the preventative measures and good operating practices! Hence this article.


The aim is to change the direction and stress the importance of development concepts. If I do not convince you, build a large, complex, and automated plating line (plating on plastics or on Ti alloys) and come back to this thought!


Troubleshooting guides are a treasure:

The author does not aim to belittle the value of a troubleshooting guide. The focus is only on conditions where there was more implicit importance on the troubleshooting guide and less on the use of development and control tools. This is analogous to leaving the head and chasing the tail. The author had used guides (long back, not any more) and cherished the experts (and plating consultants) who wrote them. Those are valuable and must be handy, but we must use as a last option. The focus on development and control will ensure you forget the art of troubleshooting (which is a good thing). Sounds good. But how?


Process Development & Control (PDC) Tools:

Advint recommends using the set of 6 Process Development & Control (PDC) tools in sequence and in a cycle.

The tools are:

1) Failure Mode and Effects Analysis (FMEA)

2) Process Checklist

3) Variable Control Charts

4) Measures of Dispersion & Variation

5) Pareto Chart

6) Cause and Effect Analysis


The listed tools are part of 7 quality control (QC) tools or statistical process control (SPC) tools. Most 7 QC or SPC tools are neither control nor statistical tools. Both terms are misnomers. A few is development and verification tools.

7 QC tools Electroplating



Quality specialists recommend starting a new unit / product or a line with a design FMEA and after a year or two conduct a process FMEA. When a process is in production mode, we recommend implementing process FMEA once a year or once in two years. No less or no more! Conducting proper FMEA’s are valuable, however it is an intense process. On processes such as automotive plastic chrome plating, FMEA is indispensable.


Process Checklist:

The purpose of the checklist is not to provide a path-breaking solution or to prevent a major potential production issues, but a few simple and frequent checks will subtly help mitigate oversights. We recommend revising the checklist once in six months or a year. The revision must include deleting redundant checks and including necessary inspections based on the feedback received from other tools and production effectiveness.


Variable Control Charts:

When you require a variable to meet only specification limit, we recommend using a run chart, and when you require a variable to meet specification and control limits, use an X-Bar R chart. One must be careful to give more emphasis on control limits when using X-Bar R charts. These charts are only effective when it set up per Dr. Shewhart’s direction and with a control and reaction plan.


Measures of Dispersion & Variation:

Examples of measures of dispersion and variation are sample and population standard deviations, range, and process sigma or standard normal distribution. Sustained observations and effective reactions to these measures are influential. We can do most of these measurements on input variables such as analyses data.


Pareto Chart:

Use Pareto’s the 80/20 concept and Juran’s “the vital few and the trivial many” thinking to your benefit on plating or conversion coating applications. Periodically, we recommend isolating top 1 or 2 defect variables and conducting a cause-and-effect analysis. Review period can be monthly or quarterly based on production or quality standards. Refer to our previous post for additional information on Pareto chart.


Cause and Effect Analysis:

You can run fishbone or 5 Why’s analysis on Pareto classifications in the same frequency. Other than Pareto classifications, we also recommend running 5 Why’s on other deviations promptly. Here, promptly means = 2 business days. The examples of deviations include quality, customer service, environment, safety, breakdown maintenances (electrical, mechanical, and chemical), etc. You must subject any deviations which you do not feel right to the cause-and-effect analysis.


                      There are other beneficial quantitative techniques and total quality management tools, including 7 quality control (QC) tools available, which we did not mention in this paper. On plating, anodizing, and conversion coatings applications we recommend applicators to use the six PDC tools implemented in sequence and continuously cycle for the best results.

Use of some of these tools are not as simple as it appears, as there are tricks and there are several variables intricately involved. Advint is with you on your quality quest.

Refer to other short papers on this site or contact for questions or further insights.


End Point:

Employee satisfaction is a prerequisite for customer satisfaction. Eliminating suspense and confirming the processes are predictable using 6 PDC tools will increase satisfaction. Always keep the plating troubleshooting guide handy, but dependence or frequent use is detrimental. Prevention is better than disposition. Good operating practices and focus on the development efforts can ensure you forget the art of troubleshooting. So influential are these tools.

Electroless Ni-P and Ni-B process management had improved significantly within the last two decades. In this paper I’ll write about the science of autocatalytic plating as practiced now and the criterions for advancement at a higher level.

The purpose is to offer reader’s deeper information to achieve consistent deposit physical characteristics and the functional properties of electroless nickel plating.

We will go over the functions of a reducing agent, stabilizer (or catalytic inhibitor), and complexing agent related to thermodynamic property of an electrolyte and mixed potential theory.


electroless nickel


Temperature (energy), electrolyte flow (current density), solution volume, and the concentrations balance determine the effectiveness of the deposition mechanism and consistency of the deposit in the long term. Gibbs free energy and its relationship with volume, temperature, and energy influence the required concentrations and ratios of a reducing agent, stabilizer, and the complexing agent. An understanding of Gibbs ∆G value with the stability, instability and absolute stability of the electrolyte is imperative. Per mixed potential theory, the deposition reaction is a combination of cathodic and anodic partial reactions taking place at separate electrodes. Redox potentials of sodium hypophosphite, dimethyl amine borane (DMAB), and sodium borohydride play a significant role in a reduction step and the concentrations of stabilizers and complexing agents.


To confirm sustained deposit characteristics, electrolysis mechanism and control or management of by products release are important. Geometrical properties such as

  • tank and pump design,
  • electrolyte volume, flow rate and pattern,
  • process control of temperature, pH, metal ion concentration, reducing agent, stabilizer, and complexing agent

will ensure stability.


When Gibbs free energy and partial electrode reactions (anodic and cathodic) are within the optimum range plating rate, deposit composition (Ni and P or B weight percentages), and formation of uniform eutectic compounds of Ni-P or Ni-B will be effective and consistent.  Corrosion and tribology properties depend on the consistency of the deposit composition and phase formation. Out of range ∆G value can lead to unstable or absolute stability of the electrolyte. This will lead to either electrolyte decomposition or very low plating rate. The concentrations of a reducing agent, stabilizer, and the complexing agent determine the stability of the electrolyte. Plating rate depends on electrolyte temperature and pH.




Other than simple control and changes done to temperature and chemical constituents, due diligence on the following variables considering the aforementioned concepts will advance the attained deposit characteristics:

  1. Optimize tank design, flow pattern and temperature stratification
  2. Aim for consistent deposit composition
  3. Observe deposit phase formation and aim for consistency if it is economically viable.

One can improve the bath life and the effectiveness of any deposit by giving more attention to the fundamental concepts and conscientiousness on the input variables. 

Though the examples cited in this paper are for electroless Ni, the recommendations apply to all electroless processes including Cu, Ag, Pd, Au, etc.

Many plating teams use quality control (QC) tools like process checklist, cause-and-effect analysis, Pareto chart, and failure modes and effects analysis. These tools are simple and powerful.

The purpose of using these tools is to minimize potential quality non-conformances. But, do all users attain alike results and are they able to meet the aim on most occasions? 


If not, why?


The benefit and actual result apply to the other 3 QC tools too! But, for the sake of simplicity let us discuss the four tools listed in the beginning. There are quite a few ways to optimize and implement these tools.


7 QC tools PDC plating


Below I had recommended the few simple and valuable practices for the specific tools.


Process Checklist:

When developing and practicing the checklist prioritizing the four features given below are significant:


Frequency—Relate productivity and the frequency of conducting the process checklist for optimum results.


Variables—Ensure the team observes important variables. The detection or measurement time of a variable must take ≤ 3 minutes. Decide the importance of a variable based on its influence of the output quality.


Time—Limit the time required to complete a checklist to ≤ 15 minutes.


Reaction Plan—Instil a mechanism to notice deviations, document, and react promptly with corrective actions. We do not require a formal correction action, but identify the cause of the effect, find a solution, and act.

The owner of the checklist must know the relationship between the reaction plan of the checklist and the preventative maintenance.



The effectiveness of the analysis depends on the facilitator and the team members. We must restrict the team members to ≤5. All participants must have either operations or subject knowledge of the effect(s). The facilitator must limit the duration of analysis and encourage pointed answers to the why’s.  


Ironically, the most common issue with this tool is working on the effects and not getting to the root cause. Though this is easily said than done, if this symptom occurs, get back to the drawing board and reflect on the team and their understanding of the tool, its limitations, and the subject.


Last, it is easy to come up with corrective actions, but the efforts are in vain if we do not fully implement the actions. Occasionally review previous cause-and-effect analyses and ensure the problem did not reoccur.


Pareto Chart:

Clarity and consistency of defects classification and the number of classes (≤ 12) observed in a Pareto chart are two crucial aspects one needs to pay attention to. Properly set up the tool, periodically use the 80 - 20 rule, and work to reduce the size of the bars. Simultaneously, work on Pareto chart and cause-and-effect analysis to achieve the best results.


Failure Modes and Effects Analysis (FMEA):

Both design and process FMEA are influential when used timely. Allot enough time and meticulously work on all potential modes. On this blog, I will resist listing all the important features of FMEA but highlight the most important routine to follow. And, that is to identify potential failure modes in full and act on the corrective actions to minimize risks. It is a tedious process but valuable.



This blog drives a simple point – using a tool might meet a procedural or an auditing guideline, but only effective use will confirm optimum results.

An effective method is open for discussion and an individual’s discretion, but a sustained focus on the end goal is imperative. And, the goal is to ensure the non-conformances do not repeat in the long term.

Succinct articulation of information on high volume, automatic and complex plating operations are essential as there are many moving parts. A great communicator is a good human and leader, who possesses cognitive empathy for their readers or followers and colleagues. He or she will also know the importance of the receiver’s absorption of the message.


There are three types of communications within a plating operation:

  1. Operating procedures
  2. Written informal operating instructions (i.e. emails and uncontrolled document displays)
  3. Verbal delivery of information

Lengthy, convoluted, and incomplete procedures defeat the purpose of its creation and existence. One should not consider writing instructions as a piece of an article to show the skills of the author, rather must shift the emphasis on the readers.

electroplating lab


Here are a few factors influencing communication:

  • The knowledge delta between the author and the readers on a particular subject.
  • Output consistency demand and reader(s) turnover.
  • Verbose communication:
    • Eases error and rework and enhances dissatisfaction.
    • Encourages a selective reading and favorable interpretation of the message.


Before we look at the qualities of good communication, let us reminisce what two stalwarts of our times had said on this subject.


Nobel Laurette Herbert Simon once said, “A wealth of information creates a poverty of attention”. 


Albert Einstein related the concise expression of thought to one’s understanding of the particular subject. He said, “if you can’t explain it simply, you don’t understand it well enough”.


From the readers’ perspective, focus’ is an important habit, and one shall acquaint themselves on the (focusing) ability of mercurial John Maynard Keynes.


Now, dive deeper and answer the below questions:

  1. Is concise expression alone enough?
  2. Don’t people forget?
  3. What is important to the author, and the reader is it always aligned?
  4. Don’t our priorities change?
  5. Doesn’t information retention power differ between people?

Here I propose a few characteristics of good communication and leave it in your able hands:

  • Enhance empathy for the reader or the follower.
  • Avoid halo effect - don’t assume and allow individual interpretation of information
  • Ensure the information is orderly, complete and easy to understand.
  • Be unambiguous about your openness to a timely revision of the procedure(s).
  • Ensure the receiver understand and agree with the message.
  • Customize information suitable to the receivers.
  • Revise, revise, revise….


After these steps, make communications accessible (visible and visual) and periodically (and proactively) reiterate the information.


Finally, in a plating operation, the operating procedures must be complete, concise, and continuously revised to reflect the present requirements. Understanding the influence and effect of empathy and focus is imperative.

Formulating cleaners such as alkaline soak cleaner and electro cleaner are imperative, though not as significant and lucrative as formulating plating baths containing primary and secondary brightener systems.

Unlike quite a few decades ago, current cleaner formulations contain methodically investigated inorganic and organic ingredients which are effective and comply with the environmental regulations. 

Different sectors and industries use solvent, alkaline soak and electro cleaners uniquely. Does the industrial practice catch up with scientific advancement? Good formulations are available! Did the market seize the opportunity? 

This blog highlights the value of a good cleaner, identifies a simple step in choosing a cleaner, and list a few potential ingredients and their properties. 

A carefully chosen cleaner can remove organic residues from the substrate thoroughly. Decrease the cleaning time and (or) improve cleanliness. Cut cost by increasing the cleaner life and minimize environmental impact.


Go over a material safety data sheet (MSDS) to select a cleaner, however, a proprietary chemical supplier could throw a curve ball. Section 2 of an MSDS must contain hazardous ingredient listed with Chemical Abstracts Service (CAS) registry number and the concentration. The reader can find specific CAS related information on this link. 


formulating electroplating cleaners


Before considering the inorganic and organic ingredients, process owner must know their processes and supply chain well. Knowing and considering the substrate(s) and their corrosion properties in most cases are explicit. Sometimes information is hidden and implicit on aspects such as oils, lubricants, and kinds of paraffin used. Application time, heat treatment (if applicable) and their intricate factors on some instances might not be clear. Source and purity of water, properties such as temporary and permanent hardness are vital for the makeup of cleaner solution and rinsing.

Alkalinity, buffer, water softening, chelation, and surface tension are a few important solution properties to observe. The process owner should assess the presence and concentrations of sodium hydroxide, carbonate, phosphate, silicate, amines, and surfactants and relate to the application (s). A surfactant can be anionic, non-ionic and (or) amphoteric. It changes the surface tension and wettability of the solution.


Briefly put, irrespective of reasons and justifications, focussing on cleaners and improving the cleaning performance is worth the effort and not a hard nut to crack using the listed suggestions.
