Abstract Corrosion protection of metals plays an important role in developing economy. Inspired by the lotus leaf in nature, superhydrophobic surfaces with excellent water-repellent properties has great potential to solve corrosion problem. Herein, superhydrophobic surfaces with improved anticorrosion performance were achieved on H62 brass. The hierarchical micro-nano structures required for superhydrophobic surfaces were achieved by integrating chemical etching and electrodeposition. After modification, fabricated structures displayed extraordinary water repellence with a static contact angle of 159.5±1.7° and a sliding angle of 3.3±0.6°. Moreover, the obtained superhydrophobic surface has very weak adhesion to water droplets and exhibits good self-cleaning properties. Finally, the corrosion resistance of the H62 brass substrate and the durability under various extreme conditions were investigated. The results show that the prepared superhydrophobic brass has excellent corrosion resistance with a corrosion inhibition rate of 89.8 % and superior durability, which will further expand its practical applications.

在 H62 黄铜基材上制备具有增强耐腐蚀性的超疏水表面

摘要 金属腐蚀防护在经济发展中具有重要作用。受自然界荷叶的启发，具有优异防水性能的超疏水表面具有解决腐蚀问题的巨大潜力。在此，H62 黄铜实现了具有改进防腐性能的超疏水表面。通过整合化学蚀刻和电沉积，实现了超疏水表面所需的分级微纳米结构。修改后，装配式结构显示出非凡的防水性，静态接触角为 159.5±1.7°，滑动角为 3.3±0.6°。此外，所获得的超疏水表面对水滴的附着力非常弱，并表现出良好的自清洁性能。最后，研究了 H62 黄铜基材的耐腐蚀性和在各种极端条件下的耐久性。结果表明，所制备的超疏水黄铜具有优异的耐腐蚀性能，腐蚀抑制率为89.8%，耐久性优异，将进一步拓展其实际应用领域。 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
