Abstract
A method for anodizing valve metal structures to a target formation voltage is described. The valve metal structures are placed in an anodizing electrolyte and connected to a power supply that generates a source voltage to at least one current limiting device. If at least two current limiting devices are used, they are in series with the valve metal structures with the one current limiting device connected to at least one structure. The valve metal structures are then subjected to a current that decreases over time, a formation voltage that increases over time to a level below the voltage from the power supply and a power level that is self-adjusted to a level that decreases excessive heating in the structure. The invention also includes the components for the method.
