High-Entropy ZrTiCrNiCu Coating

Abstract

A high-entropy alloy ZrTiCrNiCu and coating are synthesized by mechanical alloying. The microhardness of the ZrTiCrNiCu coating is not inferior and in most cases exceeds the hardness of highly entropic equiatomic alloys. The wear resistance of the ZrTiCrNiCu coating is 3⋅10 −4 g/min, which also meets the special steels for wear resistance. A high-entropy coating has a low coefficient of friction. They turn out to be anti-friction, which, in all likelihood, leads to energy savings. The surface energy, contact potential difference, and electron work function for high entropy coatings are first determined in the work.
