Aluminum alloys (Al alloys) are susceptible to corrosion due to their high chemical activity, particularly in complicated marine surroundings. Liquid-repelling Al alloy surfaces with enhanced corrosion resistance were prepared via a facile one-step chemical etching and modification with 1H,1H,2H,2H-Perfluorodecyltriethoxysilane. Results indicated that the fabricated sample with step-like micro/nanostructures exhibited excellent superamphiphobicity, which the static contact angles achieved 162?degrees, 158?degrees, and 152 for water, ethylene glycol, and hexadecane, respectively. Furthermore, electrochemical tests shed light on that the superamphiphobic surface fabricated greatly improved the anti-corrosion performance and durability of the substrate in 3.5 wt% NaCl aqueous solution. The whole process requires no special equipment, providing a facile and environment friendly method to fabricate superamphiphobic surfaces.
