Why are the copper bus bars in our plating facility nickel-plated?

Q. Why are the copper bus bars in our plating facility nickel-plated? N. I.

A. If not coated with a protective layer, copper bus bars will oxidize, forming copper salts. The copper oxides tend to flake off and fall into the plating bath. This in turn contaminates the plating bath and in time will give you problems with your plated parts. So to minimize this problem, copper bus bars often are plated with tin or nickel.
