A hierarchical superhydrophobic film has been fabricated on a magnesium alloy substrate via a facile chemical substitution method following stearic acid modiﬁcation. The characteristics of the films were investigated by scanning electronic microscope (SEM), energy dispersive spectroscopy (EDS), Fourier transformed infrared (FT-IR) spectroscopy and X-ray diffraction (XRD). The results showed that the hierarchical film surfaces with cluster structures composed of micro-sheets and stearic acid has been successfully grafted onto the sample surface. Contact angle measurements were performed to determine the surfaces wettability, and the results showed the as-prepared superhydrophobic surfaces with a contact angle (CA) as high as 167.4°. The corrosion resistance of the superhydrophobic films were estimated by potentiodynamic polarization measurement. Polarizaton measurements revealed that the superhydrophobic film coated magnesium alloy had better corrosion resistance in neutral 3.5 wt. % NaCl solution. Morever, the superhydrophobic film showed good self-cleaning property and chemical stability.
