Nanosized TiO2 particles were prepared by sol-gel method. The TiO2 particles were co- deposited with zinc from a sulphate bath at pH 4.5 using electrodeposition technique. The corrosion behavior of the coatings was assessed by electrochemical polarization, impedance, weight-loss and salt spray tests. Wear resistance and microhardness of the composite coating was measured. The smaller grain size of the composite coatings was observed in the presence of TiO2 and it was confirmed by the images of scanning electron microscopy (SEM) and X-ray diffraction ( XRD) techniques.
