Abstract:
1. A system for anodizing a valve metal body in a liquid electrolyte, the system comprising: a) a valve metal body as a porous structure capable of having an electrolyte flow therethrough and comprising a lower external surface and an upper external surface, the lower and upper external surfaces being spaced apart from each other by an intermediate perimeter; b) a container having an exterior providing a continuous passageway extending along and through a lower container region having a lower electrode, a central container region including at least one cavity for holding the valve metal body, and an upper container region having an upper electrode, wherein the central container region is dimensioned to contact the perimeter of the valve metal body held in the cavity in a substantially sealed relationship; and c) wherein the liquid electrolyte is flowable past the lower electrode and into the valve metal body by flowing through the lower exterior surface and out the upper exterior surface and then past the upper electrode while the valve metal body is maintained at an opposite polarity with respect to the lower electrode to thereby form a dielectric oxide on the valve metal body.
