| 摘 要： | 用超薄切片、透射电镜、扫描电镜、电子能谱和X射线相分析仪分别研究了铝的硫酸阳极着色氧化膜,在冷封闭制度下的微观组成。结果表明,着色阳极氧化膜在冷封闭4min之后,氧化膜的外表面层附近、表面层及深处都存在有封闭材料镍。其相对含量逐步增大至9.244％;着色材料锡在氧化膜深处达到20.420％;氧化时键合的SO_(4)~(2-)在冷封闭时部分被放出,氧化膜深处的S含量从5％降至3％左右。铝的硫酸阳极氧化膜经100min冷封闭,仍为非晶态物质。

| Abstract: | The micro Components formed anodic films on Al were studied by ultrathin section technology, TEM, SEM etc. The results show that after 4 min of cold sealing, Ni(as a sealing agent)can be found near the outer layer, surface layer and the deep place of the anodic films. Its relative content increases to 9.244%. The content of Tin (as a coloring agent)can reach to 20.42% in the deep places of the films, while the content of S in the same place decreases from about 5% to 3%. After 100 min of cold sealing, the films on Al are still amorphous substance. |
