Abstract: Ni60A alloy cladding layer containing 20wt% WC was cladded on the surface of 45 steel by high-frequency induction cladding technique assisted by mechanical vibration. The effects of mechanical vibration on microstructure, hardness and friction and wear properties of the cladding layer were studied. The results show that the cladding layer with the mechanical vibration had an excellent cladding quality. The pores in the cladding layer decreased and the structure was more uniform. Compared with the cladding layer without mechanical vibration, the surface hardness of the cladding layer with the mechanical vibration was much higher, and the friction coefficient and wear scar area were lower, indicating that the wear resistance was better.
