Abstract: To synthesize Ti-S self-lubricating wear-resistant fused cladding on TC4 surface and to investigate the effect of WC addition on the coating organization and tribological properties, a titanium-based material system of TC4+Ni-MoS2+xWC (x=5%, 10%, and 15%) was designed, and the coatings were prepared by the coaxial feeding laser cladding technique. It was shown that increasing the WC content was not conducive to the improvement of the coating forming quality, but the change of WC addition did not affect the type of precipitated phase in the coatings, and the three coatings included TiC, Ti2Ni, Ti2S and β-Ti matrix;with the increase of the WC content, the distribution of TiC increased in number and particle size, and the growth morphology evolved from spherical to petal-like;the lubrication phase MoS2 was not retained in the coatings, and its complete dissolution synthesized under the titanium-based molten pool system with similar morphology to the lubricating phase TiS, etc. The microhardness and wear-resistant properties of the three WC content coatings were higher than those of the TC4 substrate, and the wear mechanism was abrasive wear, but the friction reduction performance was not lower than that of the TC4 substrate, which indicated that the in-situ Ti2S phase did not have self-lubrication;the increase in the content of WC, although conducive to the increase in the microhardness and wear-resistant properties, but caused the coating to become more and more lubricated. Although the increase of WC content is favorable to increase the microhardness and wear resistance of the coating, it caused the decrease of the quality of the wear surface of the coating and the increase of the friction coefficient amplitude.
