The laser cladding technology on the surface of 35 steel with Ni-based self-fluxing alloy is studied. On the base of its microstructure and property of wear resistance, the cladding technology is greatly improved than that of the flame. By the studies of microstructure, mechanical property and corrosion resistance, the cladding layer with different amount of WC particle in Ni matrix is obtained.
