The film was formed in the transpassive region during the anodic polarization in H_2SO_4 and after a treatment with Na_2MoO_4. It has been found that the ratio of Cr to Fe in the film is about three times higher than that in the bulk. The analysis of the valence states showed that the distribution of each constituent in the film is not uniform. The film has a three-layer structure.The outer layer is rich in OH~- and the middle layer consists mainly of Cr_2O_3 and Fe_2O_3, while the rest of the layer up to the interface contains the Fe~(2+) and Fe~0. The Mo ions have been found throughout the film. The possible mechanism for passivation of the anodic polarization in the transpassive region was discussed and a comparison was made with other oxide films. 收稿日期: 1981-05-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张永福 包伟国 江绍猷 吕国梁 林荣富 戴道宣 董树忠 黄国柱 徐克薰 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I5/529 [1] Sugimoto, K. and Sawada, Y., Corros.
