To manufacture the better processing property coating by laser cladding self-fused Ni-based ceramic powder of ZrO2 composite on the surface of 304 SUS,cladding experiment with parameter variations was presented.The influence of the laser processing parameters on macroscopic view,microstructure and micro-hardness of the laser cladding layers was investigated.The results show that we can get better coating when laser power is 1.5 kW,and the layers have the trend of refined framework with the growing of scanning speed;micro-hardness will be higher and distribution from subs...
