FERREIRA, M. Júlia J.  and  BELO, M. da Cunha. Influence of the Chemical Composition of Stainless Steels on the Electronic Structure of Passive Films Formed in Artificial Sea Water. Port. Electrochim. Acta [online]. 2004, vol.22, n.3, pp.263-278. ISSN 0872-1904.

The electronic structure of the passive films formed on stainless steels of different chemical composition in artificial sea water is examined by capacitance measurements (Mott-Schottky approach) and photo-electrochemistry. Analytical characterization is carried out by Auger Electron Spectroscopy. The influence of the main alloying elements (Cr, Ni) on the development of space charge regions, which can be described as a depletion or accumulation layers are discussed.

Keywords : stainless steels; passive films; electronic structure.
