Abstract
NiO-ZrO2 nanoparticles were synthesized by co-precipitation method and characterized by XRD, SEM and EDAX techniques. The XRD and SEM studies were used to analyze the size and morphology of the nanoparticles. The elemental composition of the
prepared particles was detected by EDAX analysis. The particles were used in the generation of Zn/NiO-ZrO2 composite coating on mild steel by electroplating. The surface morphology and elemental composition of the coated samples were examined by scanning electron microscopy (SEM) images and EDAX analysis respectively. The anticorrosion behavior of Zn/NiO-ZrO2 composite coating was electrochemically studied by Tafel polarization and electrochemical impedance spectroscopy in comparison with pure zinc coating
