The nano-diamond anti-friction layer was prepared by laser cladding method. The microstructure, hardness and friction property of the cladding layer was studied and the anti-friction mechanism of the cladding layer was discussed. The results show that the wear resistance of the cladding layer is improved by 61.4% compared with the matrix. The hardness, self-lubricating of the cladding is enhanced by adding nano-diamond into the Fe based cladding powders and the grain of the cladding layer is refined.
