samples exhibited enhanced hydrophobicity, which increased with fluence. This improvement was attributed to the combined effects of surface roughness and adsorbed carbonaceous layers. The findings highlight the potential of ultrafast laser ablation to tailor alloy surfaces for industrial applications, though further research is recommended to assess the durability of these surfaces in real-world conditions.
