To improve the mechanical properties and corrosion resistance of zinc coatings, zinc graphene oxide (Zn-GO) composite coatings were prepared by direct current electrodeposition method. The microstructure, mechanical properties, and corrosion resistance of Zn-GO composite coatings were systematically studied using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), uniaxial tensile testing (SSRT), and electrochemical testing, and compared with traditional pure zinc coatings. The results showed that the addition of graphene oxide significantly optimized the crystal structure of the coating, increasing the tensile strength of the coating by about 6.3% and the yield strength by about 3.2%. The corrosion current density of Zn-GO composite coating was reduced by 80% compared to pure zinc coating, demonstrating excellent corrosion resistance. Zn?GO composite coating has a long corrosion resistance life. Zn-GO composite coating has high potential for application in marine anti-corrosion.
