Copper alloys suitable for laser cladding on cast iron are selected from nine types of conventional powders. There are a POOr spreading ability and porosity of copper alloy over the surface of cast iron. Copper alloy surface is easily oxidized in atmosphere. These shortuges have been overcome by adding deoxidizers of St and H3BO3. Laser parameters, stress and coefficient of friction have been examined and the larger smooth surface of Cu/cast iron for friction by laser cladding has been made for the application of the guide shoes of machine.
