摘要：

The Zn and Zn-TiO2 composite coatings were fabricated by electrolyzing respective plating solutions of Zn and Zn-TiO2. The rutile TiO2 nanoparticles (size =100nm) were used for the preparation of composite coatings. The corrosion behavior of the deposits was examined by electrochemical methods. The anticorrosive property of coatings was supported by measuring their corrosion potential, polarization resistance, charge transfer characteristic peak and break frequency. The surface morphology of deposits was studied by scanning electron microscopy, energy-dispersive X-ray diffraction spectroscopy, and X-ray diffraction techniques. The change in morphology of Zn-TiO2 composite with respect to Zn is correlated with their corrosion behavior.
