Through TEM observation of the film, the results show that the aluminum anodized under appropriate coditions have been evidently divided into three layer in which barrier-layer alumina lies between unanodized aluminum and porous-layer alumina.

• 结果表明，经阳极氧化处理后的铝片明显分成了未反应的铝、阻挡层氧化铝和多孔氧化铝3层结构，且阻挡层位于未反应铝和多孔层之间。
