The distribution of antimony within the oxide films on Pb-Sb alloy prepared by potentiostatic oxidation in H2SO4 solutions was examined by SIMS. The study of oxide films prepared by applying different potentials for three hours showed that two types of film were obtained depending on whether the potential was more negative or more positive than 1·5 V. Antimony profiles were obtained for films at several stages in the initial growth. It was found that antimony was retained in the oxide film at 1·5 V during both nucleation and two- or three-dimensional growth of PbO2 and at 1·6 V during the lateral overlaps of three-dimensional centres of PbO2. Relationships between the antimony distribution profiles and the oxide film growth are discussed.
