Abstract
Methods of preparing 7xxx aluminum alloy products for adhesive bonding and products made therefrom are disclosed. Generally, the methods include preparing a 7xxx aluminum alloy product for anodizing, then anodizing the 7xxx aluminum alloy product, and then contacting the anodized 7xxx aluminum alloy product with an appropriate chemical to create a functionalized layer. The new 7xxx aluminum alloy products may realize improved shear bonding performance.
