摘要：

In this study, we prepared a micro-nano hierarchical structure superhydrophobic 7055 aluminum alloy surface. The preparation mechanism, the surface topographies, the wettability, and the chemical compositions were characterized and discussed in detail. Results show that electrolytic polishing (EP) and etching can effectively inhibit the continuous growth of corrosion products and take grains as a unit, which has micron petal-shaped structures with the grain boundary as the boundary. The surface has a great lasting quality and the corrosive ions and liquids can hardly infiltrate the aluminum substrate and avoid the generation of chloride ion channels.
