摘要
建立了(+)Al/Al2O3/电解液(-)系统耐电压模型。在该模型中,耐电压测试时施加于样品系统上的恒稳测试电流被分离成了介质层充电电流及缺陷漏电流两部分。使用该模型对恒稳电流下铝阳极氧化膜耐电压随时间的变化进行了模拟,模拟结果与实测值几乎完全重合,并准确预测出了铝阳极氧化膜升压时间及180s时的耐压值。另外,对铝阳极氧化膜耐电压曲线进行了初步解释。
A withstanding voltage model was built for the (+)Al/Al2O3/electrolyte(-) system, in which the constant current applied on the sample system in the withstanding voltage test was separated into charge current and leakage current. And, the model was used to simulate the withstanding voltage variation of the aluminum anodic oxidation film versus time. The simulation curve agrees well with the experimentally obtained curve, and the step time and the withstanding voltage (180 s) of the aluminum anodic oxidation ...
