Abstract

Abstract: Magnetron sputtering technology is widely applied in the decorative plating of high-grode products. The Ti/TiN/TiCN composite films were deposited by magnetron sputtering process on the substrate of aluminium alloy.The TiCN films with different colour were prepared by changing the processing parameters of nitrogen flow rate,acetylene flow rate and deposition time.The ways to improve the microhardness and bonding strength of the composite film and to improve the decorative and protective properties of the aluminum alloy surface are also discussed.The results show that by controlling the process parameters,such as nitrogen flow,acetylene flow,sputtering time,the TiCN film presents certain color,such as “luxury-gold-colored”,when the compositefilms thickness at 1.5 microns,the composite films pencil hardness of 6 H,adhesion reach level 1,meet the test standard of 3C industry.

Key words: magnetron sputtering, aluminum alloy, Ti/TiN/TiCN composite films
