Abstract

Marine corrosion and biofouling seriously affect the service life of marine structural materials, resulting in performance failure, enormous economic loss, and even catastrophic safety accidents. It is worthwhile and desirable to develop high-efficiency strategy for anti-corrosion and anti-biofouling. In this paper, superhydrophobic 5083 aluminum alloy (AA5083) surface with micro-nano hierarchical morphology was fabricated through anodization followed by 1H,1H,2H,2H-perfluorooctyltriethoxysilane (POTS) modification. The surface morphologies, roughness, and chemical compositions were revealed by scanning electron microscopy, atomic force microscopy, and X-ray diffraction. The self-cleaning ability, corrosion resistance and algae adhesion suppression ability of the fabricated surfaces were investigated, indicating an excellent water-proofing, anti-corrosion and anti-biofouling performance. We believe the superhydrophobic creation of metallic materials is expected to have potential applications in marine corrosion and anti-biofouling fields.
