摘要：
The mass-transfer kinetics, the mechanism of formation, the tribotechnical characteristics, and the resistance to high-temperature oxidation of a coating formed on the hard alloy WC - 6% Co and on the titanium alloy VT6 by electric-spark alloying with electrode material based on TiCN - AIN with an Fe - Cr binder have been investigated The phase distribution of the components in the coating was shown to be the same for both alloys. Electric-spark alloying of WC - Co and VT6 was found to reduce their wear by 33 and 60%, respectively. Moreover, the working temperature of the coated WC - Co alloy increased by 160 deg compared to the original surface.
