Popis:	By using the approaches of contact mechanics, we analyze the influence of laser alloying with Nb, B, and Ni on the behavior of the parameters of wear resistance of 12Kh17T steel. It is shown that, in the process of operation of the components in the case where the force load is much lower than the yield strength of steel, it is reasonable to perform laser alloying by using a CO2 -laser with a power of 800 W. At the same time, in the case where the load is equal to the yield strength, it is reasonable to apply a laser with a power of 6.5 kW which increases the contact strength of the subsurface layers.
