Abstract: To meet the requirement of wear-resistant protection for titanium alloy surfaces, SiC/NiCrAl composite protective coatings with different SiC contents were prepared on the Ti6Al4V surface by laser cladding technology. The microstructure, microhardness, tribological properties, and corrosion resistance of the composite coatings were characterized by analyzing phases, surface morphology, element distribution, friction performance curves, and electrochemical performance curves. The results indicate that the coatings have no obvious defects such as pores and cracks. The prepared XSiC/NiCrAl composite coatings are mainly composed of Cr₂Si phase, TiC phase, (Ti, Al)-rich FCC₂ phase, (Ni, Ti, Al)-rich BCC₃ phase, and (Ni, Al, Si)-rich BCC₂ phase. With the increase of SiC content, new phases of TiC and (Ni, Al, Si)-rich HCP₁ are formed in situ in the coatings, and the surface microhardness and wear resistance increase accordingly, while the corrosion resistance gradually decreases. Among them, the NiCrAl-6SiC coating has the highest average microhardness and the smallest wear weight loss (919.4 HV_0.3, 0.6 mg). The average microhardness and wear weight loss of the NiCrAl-4SiC coating (895.6 HV_0.3, 0.8 mg) are close to those of the Ni60-6SiC coating, and its corrosion resistance is more excellent; therefore, the NiCrAl-4SiC coating exhibits a superior comprehensive performance.
