| Abstract: | Laser cladding of Fe-Ni-Cr-B-Si alloy on AZ91D alloy surface was achieved by two-step method,i.e.thermal spraying and laser re-melting.The microstructure and properties of cladding layer were investigated.The resutls show that the surface layer is composed of phases of FeCr,FeNi and AlNi3.The micro-hardness,wear properties and corrosion resistance are considerably improved as compared to the matrix. |

| Keywords: | two-step method laser cladding micro-hardness corrosion resistance wear properties |
