A modified composite of titanate and polymer (PVC) on the surface of carbon steel was investigated. The anti - corrosion performance of the modified specimen in various solutions was discussed by using some electrochemical techniques

such as polarization curve

polarization resistance and electrochemical impedance spectroscopy. The surface composition and structure of the modified film were analyzed by surface analysis techniques. The results showed that the modified composite film has good anti - corrosion performance in H2SO4 and NaCl solutions. The formation mechanism and protection mechanism of the modified film were discussed.
