Corrosion behaviour of super-hydrophobic electrodeposited nickel-cobalt alloy film

- Superhydrophobic Ni-Co film was fabricated with electrodeposition method followed by exposure the surface in air.
- The better corrosion performance were ascribed to the superior water-repellent property of Ni-Co film.
- The stability of the air trapped in the grooves were responsible for the chemical durability of the superhydrophobic film.
