Superhydrophobic film was prepared on magnesium alloy AZ31B by one-step immersion process for 30 min. The solution for immersion process was composed of an aqueous solution containing Ce(NO3)3 and ethanol containing myristic acid. The water contact angle of the prepared film was more than 150 degree and found to be superhydrophobic. The film was composed mainly of crystalline myristic acid. The corrosion behavior of the superhydrophobic film in 5 mass% NaCl aqueous solution were investigated by polarization curve. The corrosion resistance was considerably improved by preparing the superhydrophobic film. In addition, the corrosion process of the superhydrophobic AZ31B was also investigated using XRD, SEM, and water contact angle measurement.
