Dynamics of high-temperature oxidation accompanied by scale removal and implications for technological applications

The dynamics of a broad class of high-temperature oxidation accompanied by scale dissociation, volatilization, corrosion and erosion is theoretically analyzed through a dimensionless Tedmon's equation. The dependence of early stage, transition and asymptotic dynamics on oxidation (parabolic) and scale removal (linear) rate constants, and oxide initial conditions, are classified into distinct and universal categories. This analysis provides a simple yet powerful roadmap to study material performance in many technologically important applications, including the use of early stage measurement to predict long-term behaviors and screen materials
