PROCESS FOR DEPOSITING SILVER/GRAPHITE DISPERSION-PROCESS FOR DEPOSITING SILVER/GRAPHITE DISPERSION-HARDENED COATINGS HARDENED COATINGS

摘要

A prior art process for depositing silver/graphite dispersion coatings uses an electrolyte containing potassium silver cyanide, conducting salt, graphite, wetting agents and a brightener. In order to produce silver/graphite dispersion coatings using an electrolyte not containing free cyanide and using relatively high current densities, the deposition of the coating is carried out with an electrolyte containing a conducting salt which contains no free cyanide. The process enables silver/graphite dispersion coatings with graphite contents of 1-2.5% to be produced. DC1-37263
