摘　　要：为了研究稀土离子对`多孔氧化铝膜形成过程的影响,在0.3mol/L硫酸电解液中添加不同浓度的Ce^(4+),对铝片进行阳极氧化,并运用SEM、XPD对所得氧化膜进行了表征。通过得到的多孔氧化铝膜发现,Ce^(4+)在电解过程中改变了阳极化过程的电流强度,但没有改变阳极化的基本过程;Ce^(4+)的加入可使多孔排列更加有序,但Ce^(4+)没有参与膜的构成。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.
