It is shown that a positive impact on the characteristics of the surface hardening provides increased load and increasing the number of passes in obkatyvanii and supply of nitrogen into the chamber in the second stage of heat treatment standard alloy 750 ° C for 3 hours. The parameters of rolling of the following modes and thermal diffusion of nitrogen saturation when combined with heat processing in one technological cycle, in which when combined treatment (rolling + nitriding) surface alloy VT22 formed near surface hardened layers, structure, level of hardening and surface quality which provide high tribological characteristics paired with bronze BrAZhN 04/04/10.
