摘要: <正> 一、前言研究钝化现象对金属腐蚀与防护具有重要意义。关于钝化本质的成相膜理论和吸附理论对钝化现象的解释,都各有其成功与不足之处。正如文献[1]所指出的:两种理论的差别并不完全是对钝化现象的实质看法不同,还涉及钝化现象的定义及吸附膜、成相膜的定义。因此,研究

Abstract：The effect of molybdate on titanium anodization processes and the essential aspect of passivity of Ti anodized in aulfuric acid is studied with spectro-electrochemical methods. The results indicate that the molybdate could enhance the corrosion resistance of Ti not only by formation of compact surface film of oxides, but also by the adsorption of molybdate inside the pores of oxides to prevent the corrosive anions approaching Ti substrate and the Ti ions of substrate passing out of the films. The ellipsometric spectroscopy is useful for studying the adsorption phenomenon accompanied with the formation of the passive films on surface.
