Q. Is it possible to chrome plate over a nitrided part? —M.M.

A. Yes, you can chrome plate over a nitrided part. The most critical part of the process is to etch the surface properly prior to plating. Acids should not be used in this process because of the risk of hydrogen embrittlement. Two possible ways of preparing the surface is using sandblasting or tumbling. After plating, the parts should be heat-treated.
