Ion-Plasma Sprayed Coating as a Protective Decorative Coating for Copper-Nickel Alloy

摘要

This article is devoted to studiing the ion-plasma sprayed coating on the surface of copper-nickel alloy obtained by complex titanium nitride and zirconium nitride treatment. To evaluate the coating microhardness we use the method that provides the obligatory penetration of diamond-pointed pyramid through nitride layer. It is shown that nitride coating microhardness is much higher than the copper-nickel alloy microhardness. Furthermore, surface treatment provides the color of the nitride coating just as gold plated.
