摘要
A new method has been studied to obtain TiN-Ti(C,N)composite film by laser-induced re- action in order to modify the surface properties of substrate.An apparatus for this new technology has been developed.The main reaction,the influence of main processing parameters on the formation, composition,microstructure and properties of the film have been researched.The average hardness of the film is up to HK 2700-2800.The wear resist- ance of the film is higher than that of the substrate by a factor of 9-11;and the film has good adhesive strength with the substrate.
