Fabrication of Superhydrophobic Ni-SiO₂ Nanocomposite Coating with Excellent Corrosion Resistance on Mild Steel

Abstract:

Superhydrophobic surfaces were fabricated on mild steel substrate by electrochemical deposition technique. The morphology of superhydrophobic coating shows a hierarchical structure, the contact angle of water on which is up to 160.1° and the sliding angle is about 1°. The corrosion resistance of as-prepared samples was measured by potentiodynamic polarization curves. The results show that the sample with superhydrophobicity provided better protection against corrosion. The corrosion potential of the sample was found a remarkable drift positively and the corrosion current density decreased sharply compared with which show high adhesion. This route may offer a potential possibility to fabricate superhydrophobic surfaces in large scale in industry and easy to generalize it to other metal materials.
