Abstract: Three kinds of NiCr/TiC, NiCr/TiC-Cu and NiCr/TiC-Cu-WS₂ composite coatings were successfully prepared on the surface of 30 CrMnSi manganese steel by laser cladding in order to improve wear resistance of the loader bucket. The microstructure and phase composition of the corresponding cladding layer were analyzed by scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction. The wear resistance and hardness of the coatings were comprehensively evaluated by friction and wear test and microhardness test. The NiCr/TiC coating had a dense structure without any obvious pores and cracks. The major components of this coating were γ-（Ni,Fe） solid solution, hard TiC and elemental Cr, and the hardness of the coating was about 2. 5 times higher than that of the substrate. A large number of furrows were formed on the coating by wearing with the dual part, and the main wear mechanism was abrasive wear and fatigue wear. Due to the addition of soft metal Cu, the microhardness of NiCr/TiC-Cu composite coating decreased, and the friction coefficient and wear volume of the coating also decreased. Only a few furrows existed on the worn surface, and the main wear mechanism was adhesive wear. The NiCr/TiC-Cu-WS₂ coating contained γ-（Ni,Fe） solid solution, hard TiC and Cu, and also contained composite carbide（ TiWC₂） and a little of lubricating phase（CrxSy）. Only a very weak furrows existed on the worn surface of the coating, and wear mechanism was adhesive wear and micro-plough wear.In the nickel-based composite coating prepared by laser cladding, the hardness of the coating was significantly improved due to the existence ofTiC, and the lubrication performance of the coating was improved by the addition of Cu, and the lubrication performance of coatings was further improved by the synergistic effect of Cr_xS_y, Cu and TiWC₂. Among the three composite coatings, the NiCr/TiC-Cu-WS₂ coating obtained optimum anti-friction performance.
