摘要:

基于多弧离子镀技术制备了一种新的高容量电容器用TiCN/Al复合铝箔, 研究了C2H2和N2流量比及沉积后冷却方式对TiCN/Al复合铝箔比电容的影响. 通过极化曲线的测定, 对比研究了TiCN/Al复合铝箔和传统工艺刻蚀铝箔的耐蚀性能. 研究结果表明, 多弧离子镀技术制备的TiCN/Al复合铝箔的比电容高达1600uF/cm2, 比传统工艺刻蚀的铝箔提高约2倍. TiCN/Al复合铝箔在电容器用电解质溶液中存在较宽范围的稳定钝化区, 其耐蚀性能明显高于传统工艺刻蚀铝箔.

Abstract:

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.

Key words: multi-arc ion plating, capacitor, aluminum foil, corrosion resistance
