摘要

室温下将镍铝青铜浸泡在 9 wt% 的 FeCl3-6H2O 溶液中 40 分钟，成功制备出了由微米和亚微米针状结构相互连接的迷宫式微结构。经 1H、1H、2H、2H-全氟癸基三乙氧基硅烷（FAS-17）改性后，微结构表面显示出强大的低粘附性超疏水性，其水接触角大于 160°。此外，该超疏水表面在 3.5wt % 的氯化钠水溶液和不同 pH 值的腐蚀溶液中表现出优异的耐腐蚀性和稳定性。

Fabrication and anti-corrosion performances of robust superhydrophobic surface on NAB via solution-etching

A labyrinth microstructure interconnected by micron and submicron acicular structures was successfully prepared by immersing nickel-aluminum bronze in 9 wt% FeCl3·6H2O solution at room temperature for 40 min. After being modified with 1H, 1H, 2H, 2H-perfluorodecyltriethoxysilane (FAS-17), the microstructure surface displays robustly low-adhesion superhydrophobicity, and the water contact angle is above 160 ° on it. In addition, the superhydrophobic surface exhibits excellent corrosion resistance and stability in 3.5wt % NaCl aqueous solution and corrosion solution with different pH values.
