Q. I am new to plating and want to learn more about the various processes used in our plating department. Please suggest some techniques for copper and tin plating and good plating techniques in general.
Our decorative chromium plating tank is giving me fits! We have heavy chrome burning on the high-current-density areas and frequent staining. The chromium burning does not occur all the time. Can you suggest some things for me to investigate to solve this problem?
What are the requirements for college students to start a pilot study to conduct experiments on a laboratory scale? We also need process flowcharts for various plating baths on different base materials and information on how to use a Hull cell.
We are having trouble plating electroless nickel/boron nitride. The base material is carbon steel. Seventy-five to 80 percent of the parts plate satisfactorily, but the rest of the parts do not plate at all. Can you offer any suggestions on how to solve this problem?
I have a business making belt buckles and currently have an oversupply of silver-colored buckles. Is it possible to refinish them in a gold or brass color? If so, what type of company should I contact to do the job for me?
Our company plates hard chrome on hydraulic rods as well as other parts. For many of these parts we apply a flash chrome plate prior to plating with hard chrome. Is there any rule of thumb as to whether we should be using a current density of 2-4 ASI?
We are using ion exchange treatment for wastewater from nickel-chrome and zinc plating. The metal rinses are passed through the ion exchange process to remove the presence of nickel, hex chrome and zinc metal ions. The “clean water” is re-used to rinse our plated parts, but we find that it attacks the bright zinc finish. What kind of characterization do we need to do to identify the pollutants that cause this?
