In this paper, thermodynamic modeling of a powder self-fluxing material PGSR-2 based on nickel (wt. %): Ni-79.3, C-0.5, Cr-15, Si-3.2, B–2 was carried out. The simulation was performed in the temperature range of 300-6000 K in the atmosphere of “92 vol. % air + 8 vol. % propane” at a total pressure of P = 105 Pa. The temperature dependences of the equilibrium composition of the condensed and gas phases formed during heating are calculated.

The plasma modification unit UPM MAK-10 developed in IMET UrO RAS was used for surface hardening samples of 35KhGSA steel. As a result, it leads to an increase in the tribological characteristics of products (hardness and wear resistance, etc.) and, consequently, increases the service life of various machines and mechanisms.
