Electroplating is a hazardous industrial process which is now the object of Government and business initiatives to reduce environmental pollution. In particular, plating is used to coat thick chromium on electronics and aerospace components. The proposed approach uses a cathodic arc to produce a very high rate deposition of chromium onto a workpiece while avoiding the toxic chrome compounds of plating baths. Novel techniques are described to augment the flux to a rate actually exceeding plating itself, yet producing a low stress, thick coating on complex-shaped parts. The process could also be used for cadmium and zinc plating. As regulations and directives increasingly limit chrome plating in the U.S., an alternative and environmental safe chrome coating technology is essential.
