In this study, CoCrFeNiYx (x = 0, 0.1, 0.2, 0.3) high entropy alloy (HEA) coatings were produced on Ti6Al4V by laser cladding. The influence of Y on the microstructure and mechanical properties of CoCrFeNi HEA coatings was systematically examined. The analysis uncovered that the coatings primarily consist of three principal phases: α(Ti), Ti2Ni, and TiC. The incorporation of Y led to enhanced lattice distortion, which positively influenced solid solution strengthening. Moreover, grain refinement resulted in a denser microstructure, significantly reducing internal defects and thereby enhancing the coating’s performance. The average microhardness of the CoCrFeNiY0.2 coating was 702.46 HV0.2. The wear rates were 1.16 × 10−3 mm3·N−1·m−1 in air and 3.14 × 10−3 mm3·N−1·m−1 in a neutral solution, which were 27.0% and 30.8% lower than those of the CoCrFeNi coatings, respectively, indicating superior wear resistance. The Y content in the CoCrFeNiY0.3 coating was excessively high, resulting in the formation of Y-rich clusters. The accumulation of these impurities at the grain boundaries led to crack and pore formation, thereby reducing the wear resistance of the coating. Our study demonstrated that laser cladding an optimal amount of Y-doped CoCrFeNi HEA coatings on the Ti6Al4V substrate significantly enhanced the microstructure and mechanical properties of the substrate, particularly its wear resistance in both air and neutral environments, thereby improving the durability and reliability of titanium alloys in practical applications.
