Abstract
Superamphiphobic surfaces were prepared on 5052 aluminum alloy substrates by combining iron salt etching and water bath process. After modification, the contact angles of this surface with water and ethylene glycol reached 157.5° and 152.5°, respectively. And the sliding angle was 1°, exhibiting excellent superamphiphobicity. In comparison to the substrate, the corrosion potential of the superamphiphobic sample shifted positively by 745 mV, and the corrosion current density reduced from 3.745 × 10−6 A·cm−2 to 5.395 × 10−9 A·cm−2. Besides, the anti-corrosion performance was still superior to the substrate after a 7-day immersion in 3.5 wt% NaCl solution.
