| Abstract: | Boron, Silicon and Chromium are adopted to enhance hardness and wear of cladding, rare earths are used to advance whole performance of the cladding. By means of orthogonal experimental design method to design the Fe-alloy (Fe-Cr-Ni-B-Si-RE).It is discussed that there are some imperfections caused by analysis of surface quality, spectrum ingredient, hardness and microstructure. It is found that perfect ingredient about the laser cladding of iron-base serried alloy. |
