Abstract
A pulse current-assisted laser peen forming and hydrophobic surface preparing method for an aluminum alloy includes the following steps: placing a pretreated aluminum alloy onto a shock platform, where electrodes are respectively provided at two ends of the aluminum alloy, and flowing silicone oil covers a surface of the aluminum alloy; determining a laser energy; applying a high-frequency pulse current to the surface of the aluminum alloy through the electrodes, where a shot peening laser generates a laser beam according to the laser energy to shock the surface of the aluminum alloy, and under an action of an electrical pulse and laser shock, the aluminum alloy shows a bent arc-shaped surface, with a shock surface forming a porous micro-nano multi-stage surface; and performing chemical modification on the shock surface of the aluminum alloy to reduce a surface energy of the material, thereby obtaining a super-hydrophobic arc-shaped aluminum alloy surface.
