Statistical description of formation the surface microgeometry of the wear-resistant powder coverings at sliding friction

In work the probability-theoretic description of a friction surface of wear-resistant powder coverings is developed. At the description of microgeometry of a friction surface the macrostructure of powder section which is set by matrix statistical model is considered. The relative probabilities of the linear wear of transversal profiles are calculated, their bivariate distribution is constructed. It is shown that the developed approach qualitatively describes the reference structure of a friction surface of wear-resistant powder coverings.
