Abstract：To investigate the effect of coating Fe-Co-Ni interlayer method on the interfacial surface cleanliness of stainless steel/low carbon steel composite slabs,the orthogonal test method was used to establish the preferred process parameters for interlayer coating by Procast simulation software. Based on the simulation results,the composite slabs with coating interlayer were prepared and compared with the composite slabs made by solid interlayer embedding method to analyze the effect of different forming methods on the microsructure and mechanical properties after rolling and forming. It appears that the carbon and chromium diffusion preforms of the composite plate interlayers of both types are blocked,and the tensile and shear strength of the samples meets the requirements of the relevant standards. Compared with the embedding method,the ability to block the diffusion of chromium is significantly improved and a flatter bonding interface is obtained through the coating method. The content of inclusions and oxides were also reduced. The mass percent of oxygen of the coating method (4.1%) is significantly lower than that of the embedding method (11.1%),and the tensile strength of the coating method (531 MPa) is higher than that of the embedding method (503 MPa).
