摘　　要：用化学着色法从铬酸盐溶液中获得了紫红色不锈钢转化膜。ＸＰＳ和ＡＥＳ分析表明，膜层厚度约为１２５ｎｍ，膜层主要是由Ｃｒ、Ｆｅ、Ｎｉ和Ｏ元素组成，这些元素在膜的表面分别以Ｃｒ２Ｏ３、Ｆｅ２Ｏ３和ＮｉＯ状态存在。从ＡＥＳ深度刻蚀曲线的组成恒定区求得膜层的相对原子百分浓度约为：Ｃｒ２８．０，Ｆｅ２．６，Ｎｉ０．５。AbstractThe purple red conversion film on stainless steel was studied by AES and XPS. It was shown that the film mainly consisted of Cr,Fe,Ni and O, which existed in the states as Cr 2O 3,Fe 2O 3 and NiO in the film. The relative atomic percent contents of the film were Cr 28.0%,Fe 2.6% and Ni 0.5%.
