摘要： A metal article comprises an alloy substrate having a surface and a non-diffused metal monolayer disposed thereon. The surface has a first surface work function value Φs. The non-diffused monolayer deposited on the surface has a second surface work function value Φs that is less negative than the first surface work function value. A method for depositing the monolayer via underpotential deposition (UPD) is also disclosed.

摘要： A method of applying a protective coating with improved adhesion on an aluminum alloy component includes first pretreating the surface of a component by depositing a sacrificial protective immersion layer using a zincating or similar process. Portions of the protective immersion layer as well as portions of the underlying aluminum alloy substrate are then electrolytically etched off in an ionic liquid. A protective aluminum coating is then electrodeposited on the component in an ionic liquid

摘要： An aluminum alloy component is protected by an electrodeposited aluminum coating. An electrodeposited intermediate aluminum-transition metal alloy and/or rare earth metal alloy layer between the aluminum alloy substrate and the protective coating enhances coating adhesion and corrosion resistance. The intermediate layer is formed by room temperature electrodeposition in ionic liquids.
