| 摘 要： | 对三种高压阳极化成铝箔进行了SEM的形貌和EDS组分分析,用三种铝箔分别制成400 V,6 800 霧电容器并进行了耐久性试验对比,对电容器性能和阳极化成铝箔氧化膜形貌之间的关系进行了探讨。结果表明:隧道腐蚀铝箔的氧化膜残存的杂质离子多,容易击穿;氧化膜表面过多的羟基对电容器的漏电流影响很大。

| Abstract: | Three kinds of formed aluminum foil were analyzed by SEM and EDS.Capacitors of 400V,6800μF were manufactured using these alumium foil and the durability experiments were carried out.The connection of electric properties of the capacitors and the configuration of oxide film of aluminum foil were discussed.The results show that the impurity ions remained in the tunnel of etched aluminum foil lead to the puncture easily. Overabundance hydroxyl group on the surface of oxide film have effect on the leakage current of capacitiors. |
