N2 - Superhydrophobic and anticorrosion coating was manufactured on magnesium alloy substrate by hydrothermal method. The appearances, compositions and hydrophobicity of coated sample were subjected to X-ray photoelectron spectroscopy (XPS), Fourier-transform infrared spectrophotometer (FT-IR), X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Static contact angle instrument. In addition, the corrosion resistance behavior of the coated samples was examined in 3.5 wt% NaCl solution with electrochemical impedance spectroscopy. In comparison with the bare substrate, the corrosion current density of the superhydrophobic surface decreased by one order of magnitude, which were 7.943 × 10− 5 A/cm2 and 7.943 × 10− 6 A/cm2, respectively. The results confirmed the as-prepared coating not only show a high water contact angle of 161.7 ± 0.8° and a low sliding angle of 4.8 ± 0.9°, but also enhance the corrosion resistance of magnesium substrate in NaCl solution.
