Effect of surface treatments on the adhesion durability of aluminum alloys in warm water environment

This study investigated the degree to which adhesion durability in warm water environments is impacted by physical factors such as the initial adhesion strength and chemical factors such as high-corrosion-resistant surface treatment. From a comparison of the initial strength and the relative adhesive strength after the immersion test, it was found that the laser-treated samples exhibited the highest strength. The change in the strength of the interface between the adhesive bond and the aluminum surface during the immersion test could significantly affect the water resistance of the adhesion.
