| Abstract: | Superhydrophobic ceria on the aluminum substrate was fabricated, and its corrosion resistance was investigated by different techniques. For example, the so‐obtained superhydrophobic sample was immersed into the NaCl aqueous solution, and the variations in the surface wettability as well as the surface morphology were monitored; potentiodynamic polarization in the NaCl aqueous solution was adopted to evaluate its electrochemical corrosion resistance; a droplet of the aqueous solution HCl was dripped onto the superhydrophobic surface, and the corrosion process as well as the surface morphology after corrosion was monitored. The experimental results showed that the superhydrophobic ceria possessed a good corrosion resistance because of the entrapped air in the solid/liquid interface.
