Features of the wear of tribojoints under three-dimensional loading

The article deals with the regularities of wear and surface destruction of metals during friction under three-dimensional loading conditions (impact and slippage in two mutually perpendicular directions). The possibility of using the proposed technique for accelerated wear-resistance tests under complicated loading is shown. Results are presented of the complex evaluation of sample surface states after friction using continuous indentation and indenter scanning and of analysis of the change in the means of electron liberation from the sample surfaces. The dependence of the surface layer wear resistance and homogeneity and the surface microgeometry and power contour on loading conditions is discussed. The authors suggest the concept of wear resistance of tribosystems on the basis of the principles of structural-energy adaptation of materials in friction under various kinds of loading.
