In this paper, the experimental procedures are presented for laser cladding WC-TiN-SiC-Co high hard alloy of the carbon steel surface using a CO2 laser with am output power of 2kW. We also give a comprehensive analysis about the phase structure, the phase morphology, the distribution profile of the hardness and the resistance to abrassion of the sample after treatment. The experimental results indicate-that the mechanical properties and the chemical composition in the surface layer of material will basically changed. Furthermore, a preliminary discussion of the strengthening mechanism of high hard alloy formed by laser cladding is alto given.
