Laser cladding is a new kind of surface-strengthening technology.During cladding high-energy laser melts the cladding materials and make them coagulated into the surface of the base materials.The laser cladding coatings are made mainly in tow main methods:powder feeding and prefabricating.The grain-strengthening composite coatings could be more easily formed by prefabricating method than by powder feeding method.In this paper,Ni/SiC ceramic composite coating on the carbon steel is made by prefabricating method.The microstructure and wear-resist property of Ni/SiC cladding coating on 45 steel are studied with scanning electronic microscope (SEM) and wear-resist test.
