Abstract

The wear of parts tribounits under conditions of multicomponent dynamic loading is considered. The results of a comprehensive evaluation of the state of the sample surface after friction using continuous indentation and scanning of the indenter are presented. The analysis of changes in the methods of electron escape from the sample surface is presented. The dependence of the surface layer wear resistance and homogeneity, as well as the microgeometry and the energy contour of the surface on loading conditions is discussed. The authors suggest the concept of wear resistance tribosystems on the basis of the principles structural–energy adaptation of materials in friction under various kinds of loading. The possibility of controlling the wear resistance of the contacting parts when changing the contact time, taking into account the peculiarities of the formation of the surface layer upon contact is shown. The algorithm for controlling the wear resistance surface of steel components the tribounits is developed.
