| description | To improve the surface properties of 5083 aluminum, Al<sub>0.8</sub>FeCrCoNiCu<sub>0.5</sub>Y<sub>x</sub> (x = 0, 0.05, 0.1, and 0.2) high-entropy alloy coatings were prepared by laser cladding. The phase structure and microstructure of the Al<sub>0.8</sub>FeCrCoNiCu<sub>0.5</sub>Y<sub>x</sub> coatings were characterized by XRD and SEM. The tribological properties of the coating were tested by a friction and wear tester. An electrochemical workstation tested the corrosion resistance of the coating. The results show that when Y content is less than 0.2, the Al<sub>0.8</sub>FeCrCoNiCu<sub>0.5</sub>Y<sub>x</sub> coating is in the FCC1, BCC1, and BCC2 phases. When Y is added to 0.2, the coating appears rich in the Y phase. With the increased Y content, the hardness of the coating can increase. The average hardness of Y<sub>0</sub>, Y<sub>0.05</sub>, Y<sub>0.1</sub>, and Y<sub>0.2</sub> are 479HV<sub>0.2</sub>, 517HV<sub>0.2</sub>, 532HV<sub>0.2</sub>, and 544HV<sub>0.2</sub>, respectively. Microstructure evolution leads to an increase in the hardness of the coating. The effect of Y on the wear resistance of the Al<sub>0.8</sub>FeCrCoNiCu<sub>0.5</sub>Y<sub>x</sub> coatings is consistent with the hardness. Al<sub>0.8</sub>FeCrCoNiCu<sub>0.5</sub>Y<sub>0.2</sub> coating has the lowest wear rate, at is 8.65 × 10<sup>−6</sup> mm<sup>3</sup>/Nm. The corrosion current density of Al<sub>0.8</sub>FeCrCoNiCu<sub>0.5</sub>Y<sub>0.05</sub> and Al<sub>0.8</sub>FeCrCoNiCu<sub>0.5</sub>Y<sub>0.1</sub> coatings is in the order of 10<sup>−8</sup>, which is less than Al<sub>0.8</sub>FeCrCoNiCu<sub>0.5</sub>Y<sub>0.2</sub> and Al<sub>0.8</sub>FeCrCoNiCu<sub>0.5</sub>. The performance of each component coating is superior to that of the substrate. |
