Abstract
In this study, NiCrMoWTi HEA layer was prepared on the surface of the TC4 titanium alloy under vacuum conditions by using the double-flare surface plasma carburizing technique, which has the gradient structure of deposited layer + diffusion layer and metallurgical bonding with the substrate. The effects of different voltage differences on the micromorphology, structure, and properties of the HEA layer were also investigated. The results show that the physical phases of the HEA layer are basically the same and are composed of fcc and bcc phases. The high entropy alloy layer has a high bonding strength to the substrate, with a bonding force of 55.2 N. The high entropy alloy layer has a high bonding strength to the substrate. The surface hardness of the HEA layer is high, reaching 715 HV, nearly twice that of the substrate. The high entropy alloy layer has good wear resistance.
