Title: Effect of Ce~(4+) Ions on Formation Process of Alumina Anodized Coating
Abstract: The effect of Ce4+ ions on the formation process of anodized porous alumina film in 0.3 mol/L sulfuric acid electrolyte was investigated.The resulting as-prepared porous alumina film was characterized by means of scanning electron microscopy and X-ray diffraction.Results showed that the addition of Ce4+ led to changes in the current density during the film formation process but had no effect on the film formation process itself.Moreover,Ce4+ ions were not incorporated into the oxide film,though they helped to make the pores in the oxide film more better ordered.
