Abstract The growth mechanism of Cr2O3 scale formed when pure chromium was oxidized at 950°C in oxygen at 1 atm pressure has been investigated. Isotope tracer techniques were used to determine the growth sites of the oxide. The scale was buckled extensively, with the convex side always toward the gas, never the reverse. The following growth-mechanism is proposed. Initially growth occurs entirely by cation diffusion, with new oxide being formed at the oxide-gas interface. Then, at a time that is not the same for all parts of the scale, the growth mechanism changes to one in which new oxide is formed within the outer part of the scale.
