Abstract
A slippery surface has the capability to protect the substrate surface, which can prevent substrate corrosion in a harsh environment. However, existing slippery surfaces have the limitation of insufficient oil-locking capability for rough structures, which limits their practical application. To solve the aforementioned limitation, the authors developed a slippery surface with a good oil-locking capability. First, a wire-cutting machine tool was used to fabricate ternary coupled grooved structures on an aluminum (Al) substrate, which could increase the lubricant-storage capacity of the microstructures, and the substrate was named slippery porous surface with groove-textured aluminum (Slips-G-Al). Then, a surface durability test was performed involving lubricant shear, sandpaper wear and water impact. The chemical stability test involved acid, alkali, salt corrosion and weather resistance tests, which showed that Slips-G-Al had a good lubricant-storage capacity compared with the traditional Slips surface. In addition, the self-cleaning performance and the fog collection capability of Slips-G-Al were also studied. Finally, an electrochemical corrosion test of Slips-G-Al was carried out. The findings showed remarkable application prospects in the aerospace and shipbuilding fields.
光滑的表面具有保护基材表面的能力,可以防止基材在恶劣环境中被腐蚀。然而,现有光滑表面对粗糙结构的锁油能力不足,限制了其实际应用。为了解决上述限制,作者开发了一种具有良好锁油能力的光滑表面。首先,利用线切割机床在铝(Al)基板上制备三元耦合沟槽结构,增加了微观结构的润滑油储存能力,并将基片命名为带有沟槽织构铝的光滑多孔表面(slip - g -Al)。然后,进行了包括润滑油剪切、砂纸磨损和水冲击在内的表面耐久性测试。化学稳定性测试包括酸、碱、盐腐蚀和耐候性测试,表明与传统的slip表面相比,slip - g - al具有良好的润滑油储存能力。此外,还研究了slip - g - al的自清洁性能和集雾能力。最后,对滑模- g - al进行了电化学腐蚀试验。研究结果在航空航天、造船等领域具有良好的应用前景。
