<p>The development of environmentally friendly, high-performance coatings for aluminum alloys has become a focal point in corrosion-resistant coating research. Reducing the intensity of pre-coating surface treatments while maintaining adequate protective properties offers potential environmental benefits. This study investigates the influence of aluminum tripolyphosphate (ATP) on the formation of corrosion products on the surface of 2A12 aluminum alloy and examines its function when incorporated into epoxy and acrylic waterborne resin systems. Laser confocal microscopy and Raman spectroscopy are employed to analyze the compositional and morphological changes of the corroded substrates before and after treatment. Additionally, contact angle measurements of three different coatings containing aluminum tripolyphosphate are conducted, and electrochemical techniques are utilized to evaluate its effects on interfacial adhesion between the waterborne coatings and corroded substrates, as well as the barrier performance of the coatings in NaCl solutions. The results indicate that aluminum tripolyphosphate enhances the interfacial compatibility between the coating and the corroded substrate.</p>
