主　　题：Cast iron 

摘      要：Using electrode as laser cladding materials, the microstructure and wear resistance of laser clad layer of ductile cast iron was studied. The laser clad layer can be subdivided into the melted zone where existed large amounts of austenite, graphite nodules and some carbides, and the solid state transformation zone which included martensite and austenite below the melted zone. The Ti combined with C to form TiC increasing the wear resistance; The Co significantly increased the wear resistance compared with Ti.
