【摘要】 用阴极电沉积法在铝上获得了金黄色的钼酸盐转化膜，该膜具有良好的热稳定性。ＸＰＳ和ＡＥＳ分析表明，膜厚约为１６００Ａ，膜表面的钼以Ｍｏ（Ⅳ）存在，而膜内则以Ｍｏ（Ⅳ）与Ｍｏ（Ⅳ）共存。从ＡＥＳ深度剥蚀曲线的组成恒定区求得膜的组成为：Ｏ５５．７％，Ｍｏ２７．６％，Ｐ１１．２％，Ａｌ５．５％。更多还原

【Abstract】 Golden molydate conversion film with high thermostability is obtained on aluminium by cathodic electrodeposition.XPS and AES analyses show that film thickness is about 1600A,and that Mo is existed as Mo(Ⅳ)in the film surface but as Mo(Ⅳ) and Mo(Ⅳ)in the internal layer of the film.The relative atomic percent content(A.C.%) of the film from the elemental composition constant region of the depth profile curves by AES is O 55.7% Mo 27.6%,Ph.2%,Al5.5% respectively.更多还原
