Abstract

Abstract The paper discusses coatings of different composition and structure. The object of the study was the stage of nucleation wear of the coatings. Coatings up to 10–12 μm thick were obtained by ion-plasma deposition in a vacuum. The analytical part of the work is based on the theory of dislocations. This made it possible to create a computational model of the stage of nucleation of wear under conditions of cyclical impacts, which is problematically identified by instrumental methods. The comparison of calculated data with experimental data are given.
