Abstract CeO2 doped ZnO nanoparticles were synthesized by co-precipitation method and their size, structure and composition were characterized by XRD, SEM and EDAX analysis. The nanoparticles were used for generation of Zn-CeO2 doped ZnO composite (Zn-composite) coating on mild steel by electroplating. The surface morphology, elemental composition of Zn coated and Zn-composite coated samples were examined by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDAX) respectively. Corrosion experiments were carried out by electrochemical techniques such as OCP, Tafel polarization, Anodic polarization and electrochemical impedance spectroscopy. The electrochemical corrosion behavior of Zn-composite coating was compared with pure zinc coating. The morphology of the deposits after corrosion tests was analyzed by SEM images. Incorporation of CeO2 doped ZnO nanoparticles into Zn-matrix significantly improved the corrosion resistance property of Zn-coating.
