摘要

＜正＞Laser cladding experiments were carried out on Ti-6Al-4V alloy with Ti+33%TiC（volume fraction） powders. Laser processing parameters were studied systematically to investigate the influences on the surface quality. Microstructure, microhardness and wear resistance of the clad layer were evaluated. The results show that the laser parameter has considerable influence on microstructure and wear resistance of laser clad layer. With the optimized technical parameters, a clad layer with good surface quality and uniform microstnicture was obtained. The microhardness of the clad layer HV0.2 is 1 080, and the wear rate is reduced by 57 times.
