Abstract
The present disclosure provides a method for preparing a superhydrophobic surface of an aluminum alloy through laser peening, including the following steps: coating a surface of the aluminum alloy as an absorption layer with an organic component-containing confinement layer to obtain a coated aluminum alloy, where the organic component-containing confinement layer is a mixed organic solution including 5 mL to 10 mL of perfluorooctyltriethoxysilane (FOTS), 100 mL to 200 mL of absolute ethanol, and 30 mL to 50 mL of distilled water; and subjecting a surface of the coated aluminum alloy to the laser peening to form the superhydrophobic surface.
