摘　　要：The superhydrophobic surface was fabricated on the AZ31 alloy by the combination of the hydrotherreal treatment method and post modification with stearic acid. The superhydrophobic surface showed a static water contact angle of 157.6°. The characteristics of the coatings were characterized by scanning electron microscopy （SEM）, X-ray diffraction （XRD） and Fourier transform infrared spectroscopy （FTIR）. The corrosion resistance of the superhydrophobic coatings was investigated by potentiodynamic polarization test and electrochemical impedance spectroscopy （EIS）. The results revealed that the superhydrophobic coatings, characterized by petal-like structure significantly improved the corrosion resistance of the AZ31 ahoy.The superhydrophobic surface was fabricated on the AZ31 alloy by the combination of the hydrotherreal treatment method and post modification with stearic acid.
