Electroplate – Idaho National Laboratory
This invention provides a corrosion protection barrier on metallic structural materials, functional metals and alloys, and rare earth based magnets. The coating is formed by the electrodeposition of metallic aluminum on the surface of the metal/alloy from an alkali metal bromide (salt) plating bath. A thick, homogenous, uniform, pore-free, and adherent aluminum layer coating is formed when the substrate is made a cathode. The process enables formation of a multi-layered surface coating.
