The influence of heat impact at 200 - 1050 °C on the structure, phase composition, microhardness and tribological characteristics of a PG-10N-01 coating deposited by a gas-powder laser method due to sliding over a NiCrBSi fixed abrasive (corundum) is studied. A combined laser-and-heat treatment is suggested, which yields a heat-resistant chromium-nickel coating containing a thermally stable high-strength wear-resistant skeleton from coarse carbides and chromium borides.
