The invention provides a super-hydrophobic antifouling coating composition, which can effectively prevent local copper-rich phase by performing secondary solid solution and secondary aging treatment on aluminum alloy, changing the composition of the electrolytic solution, and controlling the power supply to be bipolar pulses. Dissolving, thereby reducing the hard anodizing defects of copper and aluminum alloys, and finally obtaining high hardness, high corrosion resistance, and low roughness, and by spraying superhydrophobic coatings on its surface, the overall physical and chemical properties of aluminum alloys can be effectively improved. |
