Abstract The Ti-C-B-Al composite coatings containing in-situ autogenous TiC, TiB, and TiAl intermetallic compounds reinforced with titanium base were prepared on the surface of Ti6Al4V substrate using titanium powder, aluminum powder, and boron carbide powder as raw materials, and the microstructure, phase composition, microhardness and nanoindentation properties of the composite coatings were investigated using scanning electron microscopy, X-ray diffractometer, microhardness tester, and nanoindentation tester. The results showed that the three powders reacted adequately with the high-energy laser beam to produce TiC, TiB, and TiAl intermetallic compound reinforced phases. The surface of the compo-site coating is smooth, with no pores or cracks inside the coating, forming an excellent metallurgical bond with the substrate, the reinforcement phase is evenly distributed in the coating, and the cladding coating has better mechanical properties than the matrix. The hardness of the coating ranged from 460HV_0.3 to 510HV_0.3. At the same time, there is a good relationship between the nano-mechanical properties and microhardness. When the m(Ti)∶m(Al)∶m(B₄C)=84∶12∶4, the prepared coating has better mechanical properties.

Key words： support membrane in-situ synthesis titanium-based composite coating laser melting mechanical property
