The formation of carbosilicidal nanostructured coatings with enhanced performance properties

Abstract

Describes the results of studies of carbosilicide vacuum ion-plasma coatings of complex composition based on carbides and silicides of metals having a nanostructure. The results of studies of corrosion resistance, heat resistance and heat resistance, as well as the results of tests on the microhardness of the formed coatings. The technology of multilayer nanostructured vacuum ion-plasma coatings based on carbosilicides with improved characteristics has been developed. It includes several stages: preliminary surface preparation, preliminary surface cleaning using non-independent high-current diffusion discharge, preliminary heating and surface cleaning with cathode material ions, formation of nanostructured coatings with alternating thin layers of varying hardness and different composition and subsequent cooling.
