To improve the corrosion resistance of magnesium alloys, super-hydrophobic (SH) coating was fabricated on the surface of ZK60 magnesium alloy coated with layered double hydroxides (LDHs) film. The electric field was introduced in the coating preparation process, and the influences of working current density on the characteristics of the coatings were researched. The results indicate that the working current densities significantly affect the microstructure of the LDHs films, which has an important impact on the hydrophobicity of the SH coatings. When the working current density is 25 mA/cm², the SH coating presents a homogenous micro-nano structure and super-hydrophobicity. The corrosion current density of the SH coating (I_corr =9×10^-7 A·cm^-2) is two orders of magnitude lower than that of the ZK60 substrate (I_corr =3×10^-5 A·cm^-2), indicating excellent corrosion resistance.
