Interfacial Regulation of Hard-Anodized Aluminum Alloy for Fabrication of a Wear-Resistant Superhydrophobic F-SiO2@PU Composite Coating with Enhanced Long-Term Corrosion Protection
Conventional superhydrophobic coatings on aluminum alloys are frequently limited by inadequate coating–substrate adhesion, poor mechanical robustness, and the vulnerability of their surface micro/nanostructures to mechanical damage. To address these challenges, a hydroxyl-rich anodic oxide interlayer was formed via har...
