The present study beneficially explores nano TiO2 incorporated hot-dip zinc coatings for the enhancedcorrosion protection of steel. Various electrochemical analyses such as open circuit potential (OCP),electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization studies were adoptedto evaluate the enhanced galvanic performance and the stability of nano TiO2 composite incorporatedcoatings. The low corrosion current density and high polarization resistance of tuned composition ofTiO2 incorporated hot-dip zinc coatings confirm its enhanced galvanic and corrosion resistant properties.The enhanced performance of TiO2 incorporated zinc coating was attributed to the combined effect ofbarrier and sacrificial behaviours.
