Abstract : This investigation was carried out to determine the effect of various chemical treatments on the surface of 2024-T3 and 7075-T6 bare aluminum alloys. After treatment various chemical elements can be found on the surface arising from the alloy constituents, the chemical solution or tap water rinse. The chemical signature of each surface should be known to assess adhesive bond durability.
