铝阳极氧化膜在去离子水中的自封闭效应
SELF-SEALING PROCESS OF ANODIZED ALUMINUM IN DE-IONIZED WATER
摘 要
采用交流阻抗法研究了工业纯铝L3阳极氧化膜在去离子水中的自封闭效应,并结合等效电路分析了氧化膜多孔层与阻挡层电化学参数的变化.结果表明,未封闭的阳极氧化膜在去离子水中浸泡初期存在一个明显的自封闭过程,导致阳极氧化膜在浸泡初期的耐蚀性提高.

Abstract
The self-sealing process of anodized aluminum in de-ionized water was studied by means of electrochemical impedance spectroscopy (EIS).The electrochemical parameters for the anodic film were analyzed by an equivalent circuit method.There was a self-sealing process in de-ionized water for the unsealed and anodized aluminum,which improved corrosion resistance of the anodized films.
