Q. What is the optimum temperature for drying gold-plated parts? Is there a point where the temperature may become detrimental to the gold-plated surface? S.G.

A. I don’t think I have a good answer for you on this question. There are a number of things that have to be considered when drying gold-plated parts. For one thing, the base material can diffuse into the gold plate, giving you a discolored, unattractive appearance. In some cases, this can happen at only moderately elevated temperatures. This is why in many cases gold is not plated directly on the base material but on a barrier layer (such as nickel) that is plated prior to plating the gold layer. If the temperature used is too high, you may get staining, which is difficult to remove in many cases. If one of our readers has investigated this in more detail, I would appreciate hearing from you.

  • Masking for Surface Finishing

    Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
