FIELD: metallurgy.
SUBSTANCE: working surface of tool or item from hard alloy on the basis of titanium carbide with nickel-chromium binding substance is irradiated with pulse heavy-current electron beam with electron energy of 10-30 keV at duration of radiation pulses of 150-200 mcs and number of pulses of 10-30; at that, electron beam radiation is performed in nitrogen-containing plasma of gas discharge at nitrogen pressure of 0.02-0.03 Pa and energy density in electron beam is 50-70 J/cm2.
EFFECT: improving operating life of tools, parts of machines and mechanisms operating under cutting, friction and abrasive wear conditions.
