ABSTRACT:
A method is disclosed for producing an anodized film on titanium, its alloys and other metals such that the film deposited will have a specific leak rate of less than one nanoamp per square centimeter at room temperature with an impressed electric field of at least five volts, where the anodization is performed in a solution consisting of liquid ortho-phosphoric acid of reduced water content in an aprotic solvent, and articles of manufacture therefrom.
