Undesirable mechanical and chemical stability is one of the most important limiting factors for the widespread industrially usage of superhydrophobic coatings. In this study, the Ni-P@Ni hierarchical nanostructured coating was synthesized using a mixed electrodeposition method as a stable coating. Wettability, corrosion resistance, mechanical and chemical stability of fabricated samples were investigated. The results of this study indicated that applying amorphous Ni-P coating on the surface of Ni nanocones improves the corrosion resistance and also enhances the mechanical and chemical stability. This procedure reduces the corrosion current density from 1.02 to 0.0076 µA.cm-2. The electrochemical impedance spectroscopy (EIS) results also exhibited an increase in Rdl with applying Ni-P coating. Also, by creating Ni-P coating after 200 cm of mechanical stability test and also immersing 8 days in 3.5% NaCl electrolyte, the hydrophobic state is maintained. This study introduces a new approach to creating stable superhydrophobic coatings.
