Abstract High voltage anodization of aluminum in mixed elect rolytes of phosphoric acid and sodium tungstate could be divided into four stage s: conventional anodization stage,initial stage of anodic deposition,rapid growt h stage and slow growth stage.The film formed during the first stage was differe nt from that formed either in phosphoric acid or sodium tungstate electrolyte.SE M results showed that it had a woolenlike microstructure and quickly interlace d into a web in the second stage with the increase of the voltage.The electrolytic spe cies such as PO3-4、WO2-4 and et al,aggregated toward the gel fo rmed near the oxide and transformed to the noncrystalline film through concentra tion,coagulation,dehydration and refrigeration under the combined action of elec trochemical and Joule heat effects.

Key words: aluminum high voltage anodization noncrystalline conve rsion film
