• The general kinetics of oxidation companied by scale removal such as scale dissociation, volatilization, erosion, or mass transfer corrosion is analyzed by employing a dimensionless Tedmon’s equation. Analytical expressions suitable for analyzing and fitting the oxide thickness/weight changes at early stages and long-term operations are presented. The scale of the time, oxide thickness and mass gain are specified. In addition, a perturbation solution showing the effects of the parabolic oxidation and the linear scale removal, and the combined effects of both terms are obtained. The limitation of the perturbation solution is determined. The proposed model is also applied to interpret the experimental results of steel exposed in the liquid lead-bismuth eutectic. The results show that the present model is valid for analyzing experimental results and for predicting long-term behaviors.
