| Abstract | Steel is widely used in many fields for its outstanding mechanical performance. However, the corrosion of steel has been a severe problem. In this work, we applied a fast and convenient one-step electrodeposition strategy to prepare a superhydrophobic and anti-corrosion coating on steel surface. Field-emission scanning electron microscopy (FE-SEM), water contact angle (WCA), energy dispersive spectroscopy (EDS) and Fourier-transformed infrared spectroscopy (FT-IR) were utilized for characterization. The electrodeposited layer is mainly composed of cerium myristate (Ce(CH3 (CH2)12COO)3). With the optimal parameters, the water contact angle on the coated steel surface reaches 160.1 ± 2.4°, with a sliding angle of 3°, indicating excellent water repellency. The chemical stability, mechanical stability, self-cleaning ability and water adhesion force of the coating was also investigated. The corrosion resistance of steel after electrodeposition was investigated by potentiodynamic polarization technique and electrochemical impedance spectroscopy (EIS). The polarization and EIS results suggest that the superhydrophobic coating greatly enhances the corrosion resistance of the steel substrate with anti-corrosion efficiency more than 98%. Our study shows a simple and convenient one-step electrodeposition method for a superhydrophobic and anti-corrosion coating, which we believe can be applied easily and cost-effectively to any metallic substrates to protect them from corrosion |
