Abstract—The tribological characteristics of Ni–Co–Cr entropy alloys under dry sliding friction contact deformation are studied. The results show that the hardness of the equimass alloy is 10% greater than that of the equiatomic alloy, and the use of additional alloying increases the hardness of the equiatomic alloy by 20–45%. The wear resistance of the alloys depends slightly on the hardness and, to a greater extent, on hardening due to the accumulation of subsurface defects.
