SUMMARY
Among the known antifriction materials, a separate group consists of materials designed for severe conditions, characterized by high temperatures (700-800 ◦ C) with simultaneous action of high loads (5-8 MPa) in the air. Known cast and powder nickel-based antifriction materials have high mechanical properties, high heat resistance, but they do not satisfy the operational requirements due to the high values of friction coefficient and wear rate at 700-800 ◦ C in air. The known Ni composites have alloying elements, such as Cr and V, which allow the obtainment of materials with high . . .
