英文摘要	Mg(OH)₂/graphene oxide (GO) composite film was electrochemical deposited on AZ91D magnesium alloys at constant potential. The characteristics of the Mg(OH)₂/GO composite film were investigated by scanning electron microscope (SEM), energy-dispersive X-ray spectrometry (EDS), X-ray diffractometer (XRD) and Raman spectroscopy. It was shown that the flaky GO randomly distributed in the composite film. Compared with the Mg(OH)₂ film, the Mg(OH)₂/GO composite film exhibited more uniform and compact structure. Potentiodynamic polarization tests revealed that the Mg(OH)₂/GO composite film could significantly improve the corrosion resistance of Mg(OH)₂ film with an obvious positive shift of corrosion potential by 0.19 V and a dramatic reduction of corrosion current density by more than one order of magnitude.
