Abstract
A process of forming porous electrolytic electrode in which alternating layers of a valve metal and a ductile metal are combined to form a billet, and the billet mechanically reduced by exclusion and drawing prior to etching. One or more slots are formed in the billet prior to the mechanical reducing, and filled with the ductile metal.
