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.
