Abstract
Methods are presented that includes replacing oven depolarization of a foil with a sonic vibration process for stressing the oxide. The method includes electrochemically etching the metal foil to form a plurality of tunnels in the metal foil and forming an oxide on a surface of the metal foil. The method further includes applying sonic vibration to the metal foil to induce stress fractures in the oxide, and reforming the oxide to heal at least a portion of the stress fractures.
