摘要

The electrochemical behavior of 430 ferritic stainless steel in alkaline environment was evaluated by potentiodynamic curves, electrochemical impedance spectroscopy (EIS), Mott-Schottky, X-ray photoelectron spectroscopy (XPS) and Auger Electronic Spectrometer (AES). The results confirmed that n-type semiconducting behavior of the passive film is formed on the surface of 430 ferritic stainless steel after immersion in the alkaline solution. Based on the evaluations of the passive film by AES and XPS analysis, it can be concluded that the primary constituents of the passive film is (Cr, Fe)-oxides, like the Cr₂O₃, Cr(OH)₃, FeOOH and Fe₃O₄. In addition, no chloride ions are detected in the passive film.
