During oxidation of a metal sample in air the new oxide could, in principle, form at the oxide/oxide interface, the oxide/oxide grain boundaries, the oxide/metal interface, or the metal/metal grain boundaries. The diffusional properties of the various interfaces and boundaries are discussed and a mechanism is proposed for the inhibition of the oxidation reaction by second phase particles.
