The technology of applying the gold film on the dielectric surface, based on the low-temperature reduction of the superficial sorption layer of gold chloride by phosphine gas, was developed. The sorption layer was obtained by immersing the product in a solution of gold chloride. The thickness of the coating depended on the concentration of the gold chloride solution. Adding copper chloride a film of gold-copper phosphide can be obtained. To give functional properties to the film, non-metallic particles were incorporated in the film. So when diamond particles sprayed on the wetted gold chloride surface, a gold-diamond coating was obtained containing 4.25% of diamond.
