... be exceptions, the volume ratio, as a rough rule-of-thumb, is usually correct. The Pilling- Bedworth volume ratios for many common oxides are listed in Table 2 of the article “Thermodynamics of Gaseous Corrosion” in this Volume. Defect Structure of Oxides The basic defect structures of solids were...

A pretransition regime, with a parabolic-cubic behavior controlled by the diffusion of oxygen through the entire protective oxide layer, followed by a more linear regime. The later-stage kinetics are controlled by the diffusion of the oxidizing species through...
