2時(shí)，SH涂層表面呈現(xiàn)均勻的微納米結(jié)構(gòu)，并表現(xiàn)出超疏水性。超疏水涂層的腐蝕電流密度（Icorr=9×10-7 A·cm-2）比ZK60基體的腐蝕電流密度（Icorr=3×10-5 A·cm-2）低了2個(gè)數(shù)量級，表現(xiàn)出優(yōu)異的耐腐蝕性。;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 (Icorr =9×10-7 A·cm-2) is two orders of magnitude lower than that of the ZK60 substrate (Icorr =3×10-5 A·cm-2), indicating excellent corrosion resistance."/>
