In the process of electroplating of most ferrous substrates the pretreatment is extremely important since this is where it all begins. The pretreatment process is the foundation to the rest of the process being successful. Improper pretreatment may lead to poor plate coverage, poor adhesion, premature corrosion failures, and the list goes on. In the ferrous pretreatment process the typical process consists of an alkaline soak clean to remove surface soils such as cutting and lapping oils, stamping lubes, buffing compounds, heat treat oils, and rust preventatives. The soak clean provides for … [Read more...]
The Power of My Checklist
35 years ago I was a little taller and skinnier with no gray hair and zero experience in the metal finishing world. Like so many other people, I was a little overwhelmed the first days on the job. I learned quickly that I did not know everything; in fact, I was a “plating dummy”. Time after time, I walked into plating shops, discovered a problem and had to call a technician for support. Slowly, after a few hundred incidents I knew what to check and in what order to troubleshoot my client’s problems. I had developed a checklist. Finally, I reached a point where I could honestly say I knew what … [Read more...]
Troubleshooting a Nickel Bath: Zinc Contamination
So it’s happened; someone accidentally added zinc anodes to the nickel bath. What can you do? Well, the easiest and most expensive option is to just dump the bath and make it up fresh. While this is a great way to ensure your sales representative remembers you come Christmas time, it won’t put you on your boss’ good side. Instead, you can opt to either dummy plate or complex the zinc metal out of solution. Dummy Plating Let’s take a look at dummy plating, and I’m not referring to when you have the new guy try to plate some parts. Dummy plating is a process by which we can remove unwanted … [Read more...]

What is a Procedure-Based Maintenance Organization?
When I was 19 years old I joined the Navy. I was assigned to work on submarines and spent much of my time in the service under water. Floating under the water in a hopefully airtight vessel will focus your mind on the importance of maintaining equipment. I was assigned to the Attack Submarine USS Snook (SSN-592). During my time onboard I was forced to become familiar with the “Submarine Safety” (SUBSAFE) program. In fact , the Navy taught me a few things. First, I learned the importance of check lists. Second, I was introduced to the need for standard operating procedures. Finally, I was … [Read more...]
What are you putting in your tank?
Have you ever heard the expression “the devil is in the details”? How many times do we think we have covered everything only to find out that some of the basic things get overlooked? One of the details that I find frequently overlooked is accounting for ALL components that make up a process tank. Standard Components in a Watt's Nickel Plating Bath For example, let’s take a look at a standard Watt’s nickel plating bath. The components that are commonly tested for are nickel metal, nickel sulfate, nickel chloride, boric acid, surface tension, carrier concentration, pH, and secondary … [Read more...]
What is the Timeline for GHS?
In an effort to promote standard criteria worldwide for classifying chemicals according to their health, physical and environmental hazards the Globally Harmonized System (GHS) of Classification and Labeling of Chemicals initiative was launched. Supporting this initiative, Osha has issued a Hazard Communication Standard Final Rule. This rule outlines changes for both chemical users and chemical producers to become compliant with the new GHS standards. Chemical users: Continue to update safety data sheets when new ones become available, provide training on the new label elements and … [Read more...]
