设计了一种新的单一体心立方相30 Nb 5 Ta 30 Ti 15 V 20 Zr高熵耐火合金（RHEA），该合金具有低密度、高力学性能和上级抗微动磨损性能。在这项研究中，我们专注于研究微动磨损性能与Ti6Al4V合金的比较。30Nb5Ta30Ti15V20Zr合金具有较好的微动磨损性能，摩擦系数和磨损量较低。30Nb5Ta30Ti15V20Zr合金的相组成、晶体结构及复杂成分间的相互作用有助于提高微动磨损性能。上级微动耐磨性增加了30 Nb 5Ta 30 Ti 15 V 20 Zr RHEA用于结构应用的候选潜力，特别是在微动条件下。
A newly developed single BCC phase 30Nb5Ta30Ti15V20Zr refractory high entropy alloy (RHEA) has been designed for low density, high mechanical properties, and superior fretting wear resistance. In this study, we focus on the study of the fretting wear resistance in a comparison with Ti6Al4V alloy. The 30Nb5Ta30Ti15V20Zr demonstrated the better fretting wear resistance with low friction coefficient and wear loss. The phase constituent, crystal structure and mutual interaction of complex composition in 30Nb5Ta30Ti15V20Zr contribute to improving the fretting wear resistance. The superior fretting wear resistance increases candidacy potential of the 30Nb5Ta30Ti15V20Zr RHEA for structural applications, especially under fretting conditions.
