Endowing metallic surfaces with special wettability and unique interfacial contacts broadens their wide application fields. Herein, superhydrophobic and lubricant-infused ultraslippery surfaces were achieved through chemical etching, low surface energy molecule grafting, and lubricant infusion. Systematic comparison studies of the surface wettability, self-cleaning, anti-icing, anticorrosion behaviors, and mechanical durability were carried out to reveal the functional differences and mechanisms. Both superhydrophobic and ultraslippery surfaces exhibit a distinct decrease in ice adhesion strength and a remarkable increase in charge-transfer resistance, demonstrating significantly improved ice overdelay and corrosion-resisting performance. Most notably, given the existence of a stable, defect-free, and inert lubricant-infused layer, the lubricant-infused ultraslippery surfaces possess superior mechanical robustness and long-term corrosion resistance, which provides better application potential under challenging service environments.

超疏水和注入润滑剂的超滑表面的自洁性、抗冰性和耐久耐腐蚀性的比较研究

赋予金属表面特殊的润湿性和独特的界面接触，拓宽了其广泛的应用领域。在此，超疏水和润滑剂注入的超滑表面是通过化学蚀刻、低表面能分子接枝和润滑剂注入实现的。对表面润湿性、自洁性、防冰性、防腐性和机械耐久性进行了系统比较研究，以揭示其功能差异和机制。超疏水和超滑表面均表现出冰粘附强度的明显降低和电荷转移阻力的显着增加，表明冰过延迟和耐腐蚀性能显着提高。最值得注意的是，由于存在稳定、无缺陷且惰性的润滑剂注入层，
