Abstract Two kinds of non-wetting surfaces, super-hydrophobic surface (SHS) and slippery lubricant-infused porous surface (SLIPS), were fabricated on zinc surface with hydrothermal method. Their surface properties were characterized with FE-SEM, XRD, XPS and contact angle meter, and their corrosion protection performances were evaluated with electrochemical measurements. It was demonstrated that both kinds of surfaces present high corrosion resistance to the underlying zinc substrate for the air (or lubricant) layer trapped in film. In comparison with SHS, the SLIPS presents advantage in maintaining stability in corrosive medium. This research provides guidance for the selection of non-wetting surface in practical corrosion protection application.

在锌表面上制造非润湿表面作为腐蚀屏障

摘要 采用水热法在锌表面制备了两种非润湿表面,超疏水表面(SHS)和滑润润滑多孔表面(SLIPS)。用FE-SEM、XRD、XPS和接触角仪表征了它们的表面性质,并通过电化学测量评估了它们的腐蚀防护性能。结果表明,对于困在薄膜中的空气(或润滑剂)层,这两种表面都对下面的锌基材具有高耐腐蚀性。与SHS相比,SLIPS在腐蚀性介质中保持稳定性方面具有优势。该研究为实际腐蚀防护应用中非润湿表面的选择提供了指导。
