Different thickness of barrier-type oxide film was intentionally grown on the Al metal surface and the effect of barrier film on the formation of nanoporous aluminum oxide film during anodization was investigated to control the nanopore structure. Analysis of potential transients during anodization indicated that anodic oxide film is initially overlaid on the barrier film but the anodic film is more facile to dissolve than barrier film. As the thickness of barrier film increases, both nanopore diameter and density decrease but the pore length is irrespective of barrier-film thickness.
在铝金属表面有意生长不同厚度的阻挡型氧化膜，并研究了阻挡膜在阳极氧化过程中对纳米多孔氧化铝膜形成的影响，以控制纳米孔结构。阳极氧化过程中电位瞬变分析表明，阳极氧化膜最初覆盖在阻挡膜上，但阳极氧化膜比阻挡膜更容易溶解。随着阻挡膜厚度增加，纳米孔直径和密度均减小，但孔长与阻挡膜厚度无关。
