Abstract
Surface treated titanium and titanium alloy articles having a thin anodized film substantially of TiO.sub.2 and characterized by a leakage current of less than about 25 microamps per square centimeter and a dielectric strength of at least one million volts per square centimeter, together with a high breakdown potential and high corrosion resistance, is disclosed. The process for forming such titanium and titanium alloy articles is also disclosed and is characterized by anodizing the articles in a substantially non-aqueous solution of a mineral acid and an organic solvent at a formation current above 0.1 microamps per square centimeter.
