Corrosion-resistant superhydrophobic surfaces were successfully fabricated on galvanized steel through a wet oxidation treatment and stearic acid modification. In this work, the formation mechanism of superhydrophobic surfaces and structures were characterized with contact angle meter, scanning electron microscope (SEM), X-ray diffractometer (XRD), and Fourier transform infrared spectroscopy (FTIR). The surface properties of superhydrophobic and non-superhydrophobic surfaces were assessed by calculating surface free energy (γ) and work of adhesion (W_st). Moreover, the corrosion behavior and durability of superhydrophobic surfaces were examined in 3.5 wt% NaCl solution for up to 14 days. Superhydrophobic galvanized surfaces with WCAs of 168° (γ = 0.01 mN/m and 1.57 mN/m) and 162° (γ = 0.04 mN/m and W_st = 3.52 mN/m) were successfully obtained by modifying HCl etched surfaces with ethanolic stearic acid, with or without wet oxidation. According to the results, a zinc stearate layer on the surfaces effectively enhanced their corrosion resistance by numerous air pockets on the surfaces with hierarchical micro-/nanostructures that inhibited penetration by the NaCl solution. Moreover, superhydrophobic as-synthesized ZnO surface by wet oxidation had better corrosion durability than a superhydrophobic etched surface because of the strong physical and chemical bonding of stearic acid onto the as-synthesized ZnO nanorods.

通过湿式氧化处理和硬脂酸改性，成功地在镀锌钢上制造了耐腐蚀的超疏水表面。在这项工作中，通过接触角仪，扫描电子显微镜（SEM），X射线衍射仪（XRD）和傅里叶变换红外光谱（FTIR）来表征超疏水表面和结构的形成机理。通过计算表面自由能（γ）和粘附功（W _st）来评估超疏水和非超疏水表面的表面性能。此外，在3.5 wt％的NaCl溶液中检查了长达14天的超疏水表面的腐蚀行为和耐久性。WCA为168°（γ）的超疏水镀锌表面 通过用乙醇硬脂酸在有或没有湿氧化的情况下对HCl蚀刻表面进行改性，可以成功获得 λ= 0.01 mN / m和1.57 mN / m）和162°（γ  = 0.04 mN / m和W _st = 3.52 mN / m）。根据结果​​，表面上的硬脂酸锌层通过具有分层微/纳米结构的表面上的大量气穴有效抑制了NaCl溶液的渗透，从而有效提高了其​​耐腐蚀性。此外，由于硬脂酸在所合成的ZnO纳米棒上的牢固的物理和化学键合，通过湿式氧化法合成的超疏水性ZnO表面比超疏水性的​​蚀刻表面具有更好的耐腐蚀性。
