A perturbation analysis for the metal oxidation of cylindrical geometries
The metal oxidation for two general cylindrical geometries is analyzed using a perturbation method. Unlike previous models, the reaction rate and the oxygen dissolution into metal are taken into account. One-dimensional Landau transformations is applied to transform a moving domain by volumetric expansion or contraction during oxidation into a fixed domain. The oxide film thickness predicted by the perturbation analysis is compared to that by a numerical analysis as well as to that measured experimentally.
