The long-term strength and durability of an adhesive bond is dependent on the stability of the oxide-adhesive interface. As such, changes in the chemistry of the oxide and/or the adhesive are expected to modify the interfacial properties and affect the joint performance in practice. The upcoming transition to Cr(VI)-free surface pretreatments makes it crucial to evaluate how the incorporation of electrolyte-derived sulfate and phosphate anions from, respectively, phosphoric acid anodizing and sulfuric acid anodizing affect the interfacial chemical properties. Hence, different types of featureless aluminum oxides with well-defined surface chemistries were prepared in this study. The relative amounts of O2−, OH−, , and surface species were quantified using x-ray photoelectron spectroscopy. Next, bonding with two types of commercial aerospace adhesive films was assessed by peel and bondline corrosion tests. The presented results indicate that the durability of the oxide-adhesive interface depends on the interplay between oxide and adhesive chemistries. Epoxy adhesion is highly affected by changes in the oxide surface chemistry, especially the amount of surface hydroxyls. However, the performance of anodic oxides with a lower hydroxyl fraction can be significantly enhanced by the presence of covalent bonds using a silane coupling agent, γ-amino propyl triethoxy. On the contrary, results with Redux 775 adhesive exhibit very low sensitivity to variations in the surface chemistry. Bondline corrosion resistance of the joints is mainly determined by the nature of the adhesive, independent of the varying oxide chemistries.
