Abstract
Disclosed methods include a preparing step, including induction heating at least a portion of an aluminum alloy (AA) product and optionally quenching the induction heated AA product. After the preparing step, the methods include one of a contacting step and a bonding step. The contacting step includes contacting the at least a portion of the AA product with one of: a deoxidizing agent and a functionalization solution, where between the preparing and contacting steps the method is absent of any surface oxide treating steps of the AA product. The bonding step includes bonding the at least a portion of the AA product with a second material, thereby creating an as-bonded AA product, where between the preparing and bonding steps the method is absent of any surface oxide treating steps of the AA product. The methods may be employed to produce AA products for structural adhesive bonding applications.
