On the Role of Cr in the Passivity of Stainless Steel
Source abstract
Abstract
The nature of passive films formed on 304 stainless steel at +0.25V ( vs. SCE) in deaerated solutions of and has been determined by RHEED and variable angle XPS. Evidence is given of and Cl − incorporation into the outer Fe‐rich regions of the passive film. In addition to Cr 3+ species which make up the inner layer of the film, and have been observed by XPS. The mechanism of formation of the Cr 6+ species in the solid state and the influence of the incorporated anions on the passivation process are discussed. Evidence of a bipolar mechanism operating in the passive films formed on stainless steel is discussed.
