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.

Ni-Co-Cr铸造熵合金表面强磨损时的接触变形抗力

摘要：研究了Ni-Co-Cr熵合金在干滑动摩擦接触变形下的摩擦学特性。结果表明，等原子合金的硬度比等原子合金高10%，添加额外合金可使等原子合金的硬度提高20 ~ 45%。合金的耐磨性稍微取决于硬度，而在更大程度上取决于由于地下缺陷积累而产生的硬化。

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
