| Abstract: | A 5kW CW CO2 laser has been used for surface cladding on substrate of stainless steel 1Cr18Ni9Ti. Optimal technological parameters are determined by an orthogonal design. The microstructure of the clad layer is investigated by SEM and the diffusion of carbon in the heat-affected area has been carefully studied with wave spectrum analysis. The corrosion and wear resisting behaviors of specimens are examined and compared with those by flame-sprayed and plasma-clad coating. The results are very encouraging. |
