The research study is devoted to solving the urgent problem of improving the wear resistance of metal friction surfaces of modern machinery and technological equipment. This one presents an alternative method of treatment based on changing the friction surfaces (their geometrical, mechanical and physical-chemical characteristics). The combined effect on the friction surface of a dynamic method of surface plastic deformation based on collision of working substances (fraction) from the surface to be treated under the influence of an ultrasonic field with simultaneous diffusion into the metal surface of the composite coating system based on the Fe-Ni-Cr-B-Si-Mn is investigated. In the research analytical expressions have been shown to determine the optimal chemical composition of the powder (coating system based on the Fe-Ni-Cr-B-Si-Mn), and also the expression to determine processing parameters including penetration depth of pellets on the surface. To confirm the effectiveness of the considered method for processing, laboratory tests were conducted that were aimed at determination of the depth of diffusion of the chemical powder (iron coating systems based on the Fe-Ni-Cr-B-Si-Mn) in the process of the treatment and the test of wear resistance.
