Abstract Artificial superhydrophobic surfaces have attracted increasing research interest due to their self-cleaning properties. However, their poor corrosion and temperature resistance restrict their extensive applications. In this study, an electrodeposition method was employed to fabricate a robust superhydrophobic Ni–SiO2 composite coating with temperature resistance, corrosion resistance, adhesion strength, and wear resistance properties on an aluminum (Al) alloy substrate. The Ni–SiO2 composite coating was found to have high hardness by using a hardness indenter with a load of 1,000 g. The temperature resistance was investigated by rapid temperature cycling from 100 °C to −35 °C. Corrosion resistance to acidic and alkaline environments was also presented. Adhesion strength, wear resistance, robustness, and flexibility were tested to show the stability of the coating. The proposed approach for fabricating robust superhydrophobic Ni–SiO2 composite coatings shows great potential for industrial applications.

在铝合金表面制备坚固的超疏水 Ni-SiO2 复合涂层

摘要 人造超疏水表面由于其自清洁特性而引起了越来越多的研究兴趣。然而，它们较差的耐腐蚀性和耐温性限制了它们的广泛应用。在这项研究中，采用电沉积方法在铝 (Al) 合金基材上制备了具有耐高温、耐腐蚀、附着强度和耐磨性能的坚固的超疏水 Ni-SiO2 复合涂层。通过使用载荷为 1,000 g 的硬度压头，发现 Ni-SiO2 复合涂层具有高硬度。通过从 100 °C 到 -35 °C 的快速温度循环来研究耐温性。还展示了对酸性和碱性环境的耐腐蚀性。附着力、耐磨性、坚固性、测试和柔韧性以显示涂层的稳定性。所提出的用于制造坚固的超疏水 Ni-SiO2 复合涂层的方法显示出巨大的工业应用潜力。
