Surface of Alumina Films after Prolonged Breakdowns in Galvanostatic Anodization

Breakdown phenomena are investigated at continuous isothermal (20∘C) and galvanostatic (0.2–5 mA cm−2) anodizing of aluminum in ammonium salicylate in dimethylformamide (1 M AS/DMF) electrolyte. From the kinetic 𝑈𝑡(𝑡)-curves, the breakdown voltage (𝑈𝐵) values are estimated, as well as the frequency...
