Characterization of oxide films on stainless steel exposed to hydrogen peroxide and oxygen in high temperature water

Description

The difference in electrochemical corrosion potential (ECP) of stainless steel exposed to high temperature pure water containing H2O2 and O2 is caused by differences in chemical form of oxide films. As a result of characterization of oxide films by multilateral surface analyses, e.g., X-ray diffraction (XRD), Rutherford back scattering spectroscopy (RBS), secondary ion mass spectroscopy (SIMS), X-ray photoelectron spectroscopy (XPS) and electric resistance measurement, it was confirmed that the oxide film formed under the H2O2 environment consists mainly of hematite, while that under the O2 environment consists mainly of magnetite. Higher resistance of oxide film was observed for the specimen exposed to H2O2 as a result of analyzing Cole-Cole plots measured in the elevated temperature water. (author)
