1Effect of Laser Power on Microstructure and Wear Resistance of WC_P/Ni Cermet Coating显示文摘Laser cladding nickel-based alloy coating (Ni60) and nickel-based composite coating doped with WC par-ticles by 35 %( WCP/Ni) were produced onthelow-carbon steel substrate by CO2continuous wavelaser with pow-er of 5 kWusing theinjected powder technique . The effect of laser power on microstructure and wear resistance oflaser cladding WCP/Ni cermet coating was investigated . The WC_P/Ni alloy coating with evenly distributed WCce-ramic phases and the better bond with the substrate alloy was obtained at a power of 2·2 kW. Diffusion solutionreaction happened between WC particles and the substrate alloy during laser cladding ,and led to the formation ofblock rich-tungsten carbide on the edges of the WC particles ,especially at higher power . The WC_P/Ni alloy coat-ing consists of the undissolved WC particles ,the block or dendritic rich-tungsten carbide ,the bar-like rich-chromi-umcarbide ,and dendrite solid solution and eutectic structure among the carbides . Microhardness and wear resist-ance of the WC_P/Ni coating at different powers were much higher or better than those of Ni60 alloy coating ,andthe best results were obtained at power of 2·2 kW.SI Song-hua YUAN Xiao-min LIU Yue-long HE Yi-zhu Keesam Shin 2006Journal of Iron and Steel Research(International)2006,13,3:6
