| Abstract: | Compact and cracks free NiCrBSi coatings were obtained by laser cladding on the surface of 42CrMo steel with a broad beam laser scanner,which changes the original round beam into the rectangle.Influences of microstructure of the coatings on hardness and wear resistance were investigated.Influences of different technologies on hardness,wear resistance and microstructures of the coatings were comprehensively discussed. |

| Keywords: | broad beam laser cladding microstructure wear resistance |
