Using high frequency calefaction equipment, MoSi2 ceramic powder and Ni-based self-fluxing powder blended in different proportion were cladded on W6Mo5Cr4V2 steel surface. And Ni-based alloy claddings with different MoSi2 content were obtained. The microstructure of cross-section of the claddings were analyzed; the microhardness and multi-physical parameters of the claddings were measured.
