Activation of aluminum for electrodeposition or electroless deposition

摘要

Method for treating an aluminum alloy surface for electrodeposition or electroless deposition of a metal or alloy on the surface, the surface is oxidized (e.g. anodized) to form aluminum oxide, and then the oxidized surface is chemically etched to render the surface amenable for electrodeposition or electroless deposition of the metal or alloy thereon. A metallic coating can be electrodeposited or electroless deposited on the treated surface.
