Laser cladding is an important new technology of material modification and has a good prospect.With the improvement of mechanical strength,low thickness of the cladding layer can not meet the performance requirements,so laser cladding trends to prepare the high thickness coating.Now,the single and multi-layer laser cladding techniques are the main measures to achieve the high thickness coating,and the multi-layer laser cladding is divided into a constant chemical composition multi-layer cladding (CCCMLC) and functionally gradient material multi-layer cladding (FGMMLC).The research status of high thickness coating by single-layer and multi-layer laser cladding and highlights status of the FGMMLC were summarized.Finally, the development trend of the technology in the future was prospected.

Abstract: Laser cladding is an important new technology of material modification and has a good prospect.With the improvement of mechanical strength,low thickness of the cladding layer can not meet the performance requirements,so laser cladding trends to prepare the high thickness coating.Now,the single and multi-layer laser cladding techniques are the main measures to achieve the high thickness coating,and the multi-layer laser cladding is divided into a constant chemical composition multi-layer cladding (CCCMLC) and functionally gradient material multi-layer cladding (FGMMLC).The research status of high thickness coating by single-layer and multi-layer laser cladding and highlights status of the FGMMLC were summarized.Finally, the development trend of the technology in the future was prospected.
