The resistance to surface degradation in metallic alloys plays an important role for the lifetime of the components working in harsh environments. The mechanisms involved in degradation of metallic surface in a high-temperature aggressive gaseous atmosphere include the following: forming adherent to the surface multiphase oxide layer, partial spallation, and possible vaporization of formed compounds. The governing equation, which describes a parabolic growth of adherent layer, time-dependent vaporization, and cross-linked to instantaneous thickness of adherent layer spallation rate, was suggested and analyzed. The several relationships between the kinetic constants were defined from analysis of the governing equation. Design of routes for experimental procedures to determine the independent kinetic constants was discussed and an integrated simulator was used to calculate the kinetic constants based on experimental results. Two examples of high-temperature oxidation of heat-resistant Cr/Ni austenitic steel were used to illustrate the capability of the suggested method to determine the oxidation, spallation, and vaporization kinetic constants from a single experiment. The suggested methodology could be considered in future for the analysis of different types of surface degradation of solid materials in gaseous, liquid, or solid environments.
