<p>The corrosion-induced failure of aluminum alloys in harsh environments, such as humid and chloride-containing conditions, severely constrains their service life. In this study, nanosecond laser ablation and laser-induced conversion of myristic acid to aluminum myristate are combined to propose a novel three-step method for fabricating superhydrophobic surfaces on 2024-T351 aluminum alloy. SEM, XPS and Raman spectroscopy are used to characterize the surface morphology, chemical composition, and molecular structure of the samples, respectively, to investigate the formation mechanism of the novel superhydrophobic surface. The results indicate that, under the laser fluence of 6.23 J/cm², the scanning speed of 200 mm/s, and the scanning space of 75 µm, the optimal superhydrophobic surface is achieved, exhibiting a contact angle of 161° and a rolling-off angle of 2.9°. Laser-induced myristic acid reacts with surface alumina to form stable aluminum myristate. Results from physical abrasion tests and electrochemical corrosion experiments demonstrate that the superhydrophobic aluminum alloy surface possesses excellent stability and corrosion resistance. This study provides an efficient, green, and economical method for large-scale fabrication of superhydrophobic surfaces on 2024-T351 aluminum alloy.</p>
