%X A 2 kW CO2 laser has been used to deposit Ni based WC alloy onto steel A3 substrate. The effects of ceramic-metal ingredient and laser processing conditions on the heat damage of coatings are studied. Results show that the heat damage level of WC particles in ceramic-metal composite coatings is mainly determinated by the chemical reaction between WC and binder. Further research shows that the mass fractions of carbon in binder, the kind,size and content of WC particles and the laser processing condition all directly affect the heat damage level of composite coatings.
