| 摘 要： | 发现了(NH_4)_2MoS_4水溶液中可生成铝的壁垒型阳极氧化膜。用超薄切片,透射电镜结合离子注入惰性原子标记层的技术对膜的形貌、成分和生长过程中的离子迁移进行了观察和分析;用EDAX分析方法来探测到膜中含有溶液阴离子的成分,阳极氧化过程中膜在基体/膜界面和膜/溶液界面同时生长。阳极氧化的电流密度为1.0mA/cm~2时,Al~(3+)离子的表观迁移率为0.44。

| Abstract: | It was found that barrier anodic film can be formed on aluminium in (NH4)2MoS4 aqueous solution. Ultramicrotomed sectioning allied with analytical TEM and ion implantation of xenon marker techniques were employed to investigate the morphology, chemical composition of the film and to measure the ion migration during anodizing. Species characterizing the electrolyte (Mo) was not detected in the film section with EDAX analysis. It was found that film growth proceeds at both the alumium/film and the film/electrolyte interfaces. The apparent migration ratio of aluminium ions is 0.44 when the anodizing current density is 1.0mA/cm2 . |
