Laser cladding is introduced as a process for preparing stainless steel -carbon steel metal laminated plates by cladding stainless steel powder on the carbon steel plate. The material properties, such as microstructure element diffusion, micro hardness and tensile fracture morphology, are analyzed through the metal material performance tests. The results show that laser cladding preparation of laminated plates can obtain dense and uniform layer; elements of Fe, Cr, Ni, et al. have a gradient diffusion around the combined surface and the diffusion region is about 12 μm , which indicates that combination of different materials by laser cladding belongs to metallurgical diffusion; micro hardness decreases from cladding layer to matrix, which makes a smooth stress transition between cladding layer and matrix, then enhance its overall mechanical properties; the yielded strength reaches 405 MPa and exceeds that of rolling laminated plates (326 MPa). Fracture morphology of matrix and diffusion zone belongs to ductile fracture and cladding layer is brittle fracture, further show that the interface of laser cladding laminated plates has a good combination performance.
