Abstract:In this paper, a simple, flexible method to fabricate the superhydrophobic nickel coatings by scanning electrodeposition was proposed. By changing the parameter of current densities, the morphology, microstructure, chemical composition, wettability, and stability of the samples were studied. The results showed that the clusters with hierarchical structures and the chemical composition were important in the formation of super-hydrophobic surface. The fresh coatings were hydrophilic. After placed in air for a week, the contact angles were varied from super-hydrophobic (contact angle 152.3°) to relatively hydrophobic (contact angle 112.6°) by controlling the parameter of current densities. The mechanisms of hydrophobic and forming were illustrated. Moreover, the super-hydrophobic coating possesses excellent stability and corrosion resistance, and it still maintains the corrosion protection after immersion in NaCl solution for a week. © 2019 Elsevier B.V.
