Microstructure and properties of the super-hydrophobic films fabricated on magnesium alloys

► The super-hydrophobic surface of magnesium alloy can be prepared by a simple method. ► The preparation method is simple, feasible and suitable for industrial production. ► The corrosion resistance of the sample surface was obviously improved after super-hydrophobicity treatment ► The super-hydrophobic surface has good time stability in the atmosphere.
