英文摘要	TiB2/TiB/TiNx (x=1, 0.3)/Ti composite coating was prepared on pure Ti by laser surface alloying by using powders of boron as starting materials. The composite coating was examined by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and scanning electron microscopy (SEM). The friction and wear properties of the composite coating were examined using a pin-on-disk tester under dry sliding wear condition. The results showed that the top surface of the composite coating was mainly composed of TiB2, TiB, TiN0.3, TIN and Ti phases, while the interface of the composite coating was composed of TiB and Ti phases. The composite coating showed sticklike structure near the top surface, and dendrites structure near the interface. The friction and wear test showed that the composite coating had better wear resistance than pure Ti due to their higher microhardness than that of pure Ti substrate.
