Abstract:
In a continuous electrolytic foil forming process employing a source of constant d. c. voltage, the speed with which the foil is drawn through the electrolyte is automatically adjusted by a feedback mechanism to maintain a constant value of forming current, thereby producing an oxide film whose thickness is substantially invariant over the entire length of the foil.
