Abstract
A consumable electroplating anode comprises a compacted mass of metal powder having an additive dispersed throughout the mass, having an electrically conductive path through the mass and the mass having a density in excess of about 70% of theoretical density. The metal can be nickel, cobalt, iron, copper, cadmium or any other metal available in powder form and usable as a consumable anode. The additive can be either a solid or a liquid and can be an anode activator and/or a bath component. A specific structure wherein the additive is held by the metal in a compressed state at abnormally high density is also disclosed.
