以三种不同质量分数配比为40%Ti-19.5%TiC-40.5%WS_2、40%Ti-25.2%TiC-34.8%WS_2、40%Ti-29.4% TiC-30.6%WS_2的复合粉末为预置原料,采用激光熔覆技术在钛合金TA2表面原位合成自润滑耐磨复合涂层.系统地分析了涂层的物相、组织、显微硬度及其摩擦学性能与机理.结果表明:三种涂层的显微硬度分别为HV_(0.5)927.1、HV_(0.5)1007.5和HV_(0.5)1052.3,相对于基体(HV_(0.5)180)有极大的提高;三种涂层的摩擦系数和磨损率分别为0.41和30.98×10~(-5) mm~3/(N·m); 0.30和18.92×10~(-5) mm~3/(N·m)以及0.34和15.98×10~(-5) mm~3/(N·m). WS2质量分数为34.8%和30.6%的预置粉末制备的涂层表现出较好的耐磨...

Three different self-lubrication anti-wear composite coatings were fabricated on TA2 titanium alloy by laser cladding with different powder mixtures: 40%Ti-19.5%TiC-40.5%WS2, 40%Ti-25.2%TiC-34.8%WS2, 40%Ti-29.4%TiC-30.6%WS2(w). The microstructure, phase compositions, microhardness and tribological properties of coatings were investigated systematically. The results have demonstrate that the microhardness of the three different coatings were HV0.5927.1, HV0.51007.5 and HV0.51052.3, respectively. The microhardness of coatings were improved dramatically compared with the TA2 titanium alloy (HV0.5...
