Abstract
In this study, a low-cost Nano-SiO2 super-hydrophobic hybrid coating was fabricated on the surface of 2024 aluminum alloy plate by dip coating method. The composition and structure of the coating were analysed by X-ray photoelectron spectroscopy (XPS). The morphology of the coating was characterized by scanning electron microscope (SEM) and atomic force microscope (AFM). The abrasion resistance of the coating was tested by the combination of water contact angle (WCAs) and cyclic abrasion experiments. The results identified that the maximum WCA of the coating was up to 161.6°, and the coating surface maintained the super-hydrophobic after 100 times of abrasion. This strategy shade light on the potential application in the field of solid super-hydrophobic surface industrialization.
