Abstract: In order to enhance the surface mechanical properties of SUS316, the (FeCoCrNi)₈₅(TiAl)₁₅ high entropy alloy cladding layer was fabricated on the surface of SUS316 by laser cladding technology combined with coaxial powder conveying method. The microstructure, phase composition, surface microhardness, tribological characteristics, and wear mechanism of the high entropy alloy coating were analyzed by X-ray diffraction, scanning electron microscopy, transmission electron microscope, Vickers hardness tester, and reciprocating friction and wear testing machine, respectively. The results show that the microstructure of the (FeCoCrNi)₈₅(TiAl)₁₅ high entropy alloy coating is mainly equiaaxial, with face-centered cubic(FCC)+body-centered cubic (BCC) biphase structure. The Ti-rich micron crystals are dispersed on the surface of the biphase matrix, and a large amount of 01\overline1 BCC// 01\overline1 L21 coherent precipitation exists in the BCC matrix. The Vickers hardness of the coating surface is 514 HV, which is 66.9% higher than that of the substrate. The average friction coefficient and wear rate of dry sliding friction are 0.331 and 1.936×10⁻⁵ mm³/(N·m), respectively, which show significant advantages compared with 0.418 and 2.906 ×10⁻⁵ mm³/(N·m) of SUS316. A large number of furrows and a small number of adhesive marks can be observed, which indicates that the wear mechanism is mainly abrasive wear accompanied by slight adhesive wear. The relevant work can provide guidance for the direct control of composition structure and the improvement of friction and wear properties of FeCoCrNi high entropy alloy coatings by laser cladding.
