摘要：

The reaction of O2 with a sputter cleaned Fe-25 at% Cr alloy surface has been studied at 300 K at pressures of 10(8)-10(-6) Torr in the presence and absence of water vapor, using XPS, ARXPS and ARAES. Line shape analysis and non-linear least squares fitting routines were employed to model the composition of the oxide films formed. No reaction with water vapor was observed and its presence did not influence the oxidation kinetics and the oxide film composition. The reaction with O2 yields surface oxides with concentration gradients that can be modeled by a multilayer structure. Starting from the outer oxide surface the predominant species are Fe3+, Fe2+, Cr3+, and an iron enriched layer on the alloy substrate.
