摘　　要：用化学着色法从钼酸盐溶液中获得了铁的绿色转化膜,该膜具有良好的耐蚀性。电子能谱分析结果表明,膜厚约为2000A;膜的元素组成为:O58.6％。Mo27.1％,P 10.5％和 Fe 3.8％;膜层表面 Mo以 Mo（Ⅵ）存在,而在膜内则以 MO（Ⅵ）和 MO（Ⅳ）共存。A green chemical conversion film was formed on iron from a molybdate solution. This film displayed good an-ticorrosion effect. The results of electron spectroscopy analysis showed that the thickness of the film is 2000 A-The elemental composition of the film was: O 58. 6%, Mo 27.1%, P 10. 5% and Fe 3. 8% respectively. Mo exists as Mo(Ⅵ ) in the surface of the film, while as Mo(Ⅵ ) and Mo(Ⅵ ) in the internal layer of the film.
