摘要

特殊的润湿表面因其在汽车、工程、环境和生物医学行业的潜在应用而备受关注。具体来说，自然激发的超疏水表面能更有效地阻挡湿气，从而限制腐蚀。因此，表面润湿性分析仍然是证明粗糙工程表面缓蚀特性的主要方法。在本文中，湿润性测量对在 HCl：HNO3 酸中蚀刻的 316L 不锈钢表面的腐蚀抑制性的影响进行了系统研究。有趣的是，接触角≈125°的蚀刻疏水表面可显著提高 50%的耐腐蚀性，从而抑制腐蚀速率。此外，还详细分析和讨论了蚀刻 316L 钢的表面化学状态。

Do Wettability Measurements Define Corrosion Inhibition of Etched Surfaces? A Study on Acid-Etched 316L Stainless Steel

Special wetting surfaces have attracted attention owing to their potential applications in the automotive, engineering, environmental, and biomedical industries. Specifically, nature-inspired superhydrophobic surfaces are more effective in blocking moisture, thus limiting corrosion. Hence, surface wettability analysis remains the primary method for demonstrating the corrosion mitigation characteristics of rough-engineered surfaces. Herein, the influence of wettability measurements on the corrosion inhibition of 316L stainless steel surfaces etched in HCl: HNO₃ acid is systematically investigated. Interestingly, etched hydrophobic surfaces with a contact angle of ≈125° significantly improve the corrosion resistance by 50%, resulting in suppressed corrosion rates. Furthermore, the surface chemical states of the etched 316L steel are analyzed and discussed in detail.
