Structure, Deformation, and Fracture of Hard Coatings During Sliding Friction

Аннотация

The paper considers the current state of the problem of choosing methods for surface hardening of metallic materials aimed at ensuring advanced tribological characteristics of friction pairs. Several technological processes of surface engineering are analyzed in the paper. The information on the macro- and microstructure of coatings, obtained by ion beam doping, thermochemical treatment, and vapor and gas deposition of coatings by PVD and CVD technique, is considered. The data on the wear characteristics of modified layers obtained by various techniques under dry and boundary friction conditions are presented.
