![]() From the comparison of the electrochemical parameters of different immersion times, both water-repellent coatings are effective in protecting the aluminum alloy from corrosion in simulated seawater due to reduced contact area between the metal substrate and corrosive solution. Furthermore, the corrosion resistance properties of SHS and SLIPS in simulated seawater were characterized by electrochemical measurements. The morphology and wettability of the fabricated samples were evaluated by scanning electron microscopy and contact angle measurements. Finally, the SLIPS was fabricated on the SHS by coating lubricant. Then, the SHS was prepared on the above structure by fluorosilane modification. In this work, we first fabricated a micro/nano hierarchical structure on the aluminum surface by femtosecond laser processing. However, how to prepare stable water-repellent coatings that can prevent the intrusion of corrosive ions remains to investigate. ![]() ![]() Inspired by the lotus leaf and nepenthes pitcher, the superhydrophobic surfaces (SHS) and the slippery liquid-infused porous surfaces (SLIPS) were produced as a potential strategy to prevent metal corrosion. Metal corrosion causes huge economic losses and major disasters every year.
