Experimental investigation of friction behaviors for CrCoNi medium entropy alloy in reciprocating sliding

Medium/high entropy alloys have some excellent properties, such as high strength, high plasticity, high toughness, high wear resistance, etc., which are better than those of traditional metal alloys. The mechanical properties of medium/high entropy alloys have always been the focus of academic research, but research on their interface mechanical behaviors is still missing. In this paper, we have designed a fretting friction and wear testing...
