A new TiCN/Al composite foil for capacitor negative applications was prepared by multi-arc ion plating method. The effects of cooling process and flow ratio of C2H2 to N2 for deposition on specific capacitance were investigated. The polarization curves were measured for TiCN/Al composite foil and traditional etching aluminum foil and their corrosion resistance were compared and discussed. Specific capacitance of TiCN/Al composite foil obtained is as high as 1600μF/cm2 which is over two times higher than that of the aluminum foil prepared using the traditional etching process. The TiCN/Al composite foil shows a wide range of stable passivation zone in the capacitor electrolyte solution and its corrosion resistance is significantly higher than that of the aluminum foil fabricated by the traditional etching process.
