Abstract
An aluminum alloy sheet, plate, casting or extrusion having a surface layer containing magnesium oxide and aluminum oxide is cleaned with an acidic solution. The cleaned component has an aluminum oxide layer that is pretreated with a phosphorus-containing organic acid to form a functionalized layer. A layer of polymeric adhesive is applied to the functionalized layer, and the adhesive layer is joined to a metal support structure to form a vehicle assembly.
