| Abstract: | In this paper, the research and development of laser cladding on different aspects, such as laser cladding's mechanism, parameters, microstructure, properties and application etc., are indriuced. The problems needing furtherstudy are pointed out, including the metallung quality of cladding lay, cracks, micro-eliquation, micro-stress. The developing trends of stress/strain dyndric relation, layer/matrix interface stress educing, gradient materials study, high powerlaser equipment accssories, cladding methods and stability of adding elements are also presented. |
