Abstract

A model for the distribution of individual metallic constituents (Fe, Cr, Ni, Mn) in the corrosion layers on steels in supercritical water is proposed. A detailed description of the model concept and the calculation procedure is given. To verify and validate the model, its predictions are quantitatively compared to depth profiles of the oxides on ferritic–martensitic and austenitic steels as estimated by surface analytical techniques. Estimates of kinetic and transport parameters of the oxidation process for ferritic–martensitic and austenitic stainless steels in supercritical water are obtained. Predictive calculations of the growth kinetics of the respective oxides are presented and discussed.
