Abstract
A process for preparing porous high surface over metal films for electrolytic capacitor manufacture. An anodizable metal is evaporated in a vacuum chamber to form a metal vapor, the metal vapor being directed towards a foil substrate. The deposition angle is chosen such that the evaporated metal condenses as a porous surface layer. The coated foil may be used in the manufacture of electrolytic capacitors by anodizing the coating, applying contacts, and winding up the foil.
