Abstract

The exploration of non-equimolar high-entropy alloy coating provides a broader space for the development of high-performance coatings. In this work, the microstructure, hardness, wear, corrosion, and tribocorrosion of CoCr₂FeNiMo_x (x = 0, 0.1, 0.2, 0.3, 0.4) coatings fabricated by laser cladding were investigated. The results showed that Mo addition significantly increased the hardness and wear resistance. CoCr₂FeNiMo_0.3 coating exhibited excellent performance during the synergistic effect of corrosion and wear in acidic 3.5 wt.% NaCl solution. The tribocorrosion mechanism of the Mo-containing coating was a combination of abrasion, adhesion wear, and corrosion.
