The results showed that the aperture distributed of Ti02 porous films by anodic oxidation reduce in evidence, and the morphology of the film was not very good, while add (NH4)2SO4 or (NH4)H2PO4 in the electrolyte, including HF(0.5wt%) only.

• 实验结果表明: 在单一的HF酸电解液中加入(NH+)2SO4或(NH4)H2PO4 后,阳极氧化生成的膜孔径明显减小,并且膜表面形态较差。
