对纯铝板和烧结纯铝这两种成分相同但内部结构不同的材料进行阳极氧化处理,探讨了基体对氧化膜的影响。 结果表明:致密的纯铝板经阳极氧化后,氧化膜均匀、连续,较厚且硬度较高;多孔的烧结铝经阳极氧化后,氧化膜的均匀性和连续性较差,薄且硬度低。

The pure aluminum and sintered aluminum which have same composition and different structure was treated by anodic oxidation, the influence of the base body on anodic oxidation film was discussed. The results show that the oxidation film of the pure aluminum is uniform and continuous. The oxidation film of the sintered aluminum is Poor uniformity and continuity. The oxidation film is thin and low hardness.
