Abstract The oxygen gradient beneath the oxide film on zirconium oxidized at 850 deg C for times ranging from 8 to 305 hr was measured. The technique used involves the measurement of the rate of dissolution of interference colored oxide films. Experimentally determined gradients are in good agreement with a theoretical expression involving the diffusivity, time, and oxide film thickness. Metallography and microhardness measurements demonstrated the existence of a number of phases in the oxygen containing metal substrate. These are believed to be associated with orderdisorder reactions. No evidence of zones of constant composition or steady-state gradients was observed.
