Titania-containing organic-inorganic hybrid sol-gel film was developed to improve the corrosion resistance property of steel. Titania precursor was prepared from titanium-isopropoxide and methyl hydrogen silicone was used as a coupling agent to enhance the adhesion and hydrophobic nature of coating. The kinetics, thermal resistance and morphology of films were analyzed by, fourier transformed infrared spectroscopy, thermo-gravimetric and differential thermal analysis and scanning electron microscopy. The anticorrosion performance of the sol-gel coated sample was investigated by electrochemical impedance spectroscopy. The results demonstrated that coatings were dense, uniform and provided excellent corrosion resistance properties.
