铬酸浓度对铝阳极氧化多孔膜阻挡层形成过程的影响

对铝在不同浓度的铬酸中阳极氧化多孔膜阻挡层形成过程进行研究，随着铬酸浓度的增加，阻挡层形成电流密度增加，形成阻挡层所需的时间减少，阻挡层厚度变薄。这些现象可归结为阻挡层形成时应力集中的结果。

磷酸浓度对铝阳极氧化多孔膜阻挡层形成过程的影响

The formation of the barrier layer of anodic porous alumina film has been investigated in phosphoric acid solution. The results show that with the increase of phosphoric acid concentration,the time needed to form barrier layer is shortened,and also the barrier layer becomes thinner. The phenomenon can be interpreted reasonablyby the stress concentration that developed in barrier layer.
