Abstract
Methods of preparing 7xxx aluminum alloy products for adhesive bonding are disclosed. Generally, the methods include chemical and/or mechanically preparing a 7xxx aluminum alloy product to reduce the amount of magnesium oxides while maintaining any copper-containing intermetallic particles located proximal the surface of the 7xxx aluminum alloy product. After preparation, a functionalized layer may be produced thereon for adhesive bonding.
