Abstract
Manufacturing methods are disclosed that can electropolish a metal surface by disposing an electrode over the metal surface, and a permeable dielectric spacer between the metal surface and the electrode. An electrolyte is infiltrated into the permeable dielectric spacer, and an electrical voltage differential is applied to the electrode and the metal surface.
