Method of Pretreating Aluminum Assemblies for Improved Adhesive Bonding and Corrosion Resistance

摘要

A system and a method for pretreating an aluminum assembly includes selecting a blank having a thin film pretreatment layer and a lubricant coating applied to a surface. The blank is formed to a desired shape and an adhesive is applied to a selected portion of the surface. A cleaner is applied to the assembly to remove the thin film pretreatment layer and the lubricant coating from the surface except at the selected portion and a zirconium oxide conversion coating is applied to the assembly before painting.
