- Abstract
The special wettability of superhydrophobic aluminum alloys has a broad applied foreground in important industrial fields, such as aviation, automobiles, and ships. However, the microstructures of superhydrophobic surfaces are easily destroyed, causing them to lose superhydrophobicity, which seriously restricts the application of superhydrophobic surfaces. To solve this problem, we developed a simple and low-cost fabrication method by the blasting and chemical deposition of Ni and P to process robust micro/nano-composite structures on an aluminum alloy material and then obtained a superhydrophobic nickel–phosphorus–aluminum surface (SHP-NiP-Al) with a water contact angle of 163° and a water rolling angle of 3° through low surface energy modification. The prepared SHP-NiP-Al had an excellent self-cleaning performance and antifouling property. In addition, it showed great mechanical robustness and chemical stability performance in the sand impact, blade scratch, and acid/base solution tests. It also demonstrated good corrosion resistance performance. Electrochemical corrosion tests indicated that the corrosion resistance of SHP-NiP-Al was better than that of the original aluminum. Moreover, SHP-NiP-Al could collect the water from the fog environment. This method is helpful for the practical use of superhydrophobic aluminum alloy surfaces.
