In order to improve the wear resistance of AF1410 steel,a NiCrBSi coating with 60% WC is prepared on its surface by laser cladding.The microstructure,hardness and wear resistance of the coating are evaluated by scanning electron microscopy,X ray diffraction,friction and wear tests and hardness tests.The results show that the typical phases within the coating are tungsten carbide dendrites such as WC and W2C,as well as particles distributed in the dendrite gap γ (Ni,Fe)solid solution and M23C6,M7C3 and other carbides.The hardness and wear resistance of the coating are effectively improved,and its minimum average wear rate reaches 8.78×10 -8,which is nearly 60 times less than that of the substrate.
