Abstract: The vacuum cladding technology was used to prepare WC/Ni composite cladding coating modified with different CeO2 content. The microstructure, composition and microhardness of the WC/Ni composite coating were systematically analyzed by SEM, XRD, EDS and microhardness tester. The results showed that the microstructure of composite cladding coating was dense and the interface between composite coa-ting and 45# steel substrate was metallurgical bonding. The composite cladding coating included the composite layer with network structure cha-racteristics of 2—3 mm and the transition layer of about 300 μm thickness. With the increasing of CeO2 content, the grain size of the composite cladding coating was gradually refined and its fusion quality improved, especially the fishbone precipitated phase appeared in the metallurgical fusion zone of transition layer. The main phases of the mesh hole region in the composite layer were γ-(Ni, Fe) solid solution, FeNi3, Cr7C3, Cr23C6, Ni3Si and NiB, while the main phases of the mesh line region were WC, WC2, solid solution and eutectic. The microhardness of composite cladding coating gradually decreased from the composite coating surface to 45# steel substrate, and its average microhardness gradually increased with the increasing of CeO2 content. The maximum value was reached when the CeO2 content was 1.5%, and the average microhardness was 5—6 times higher than that of the substrate.
