The aim of the present study was the electrochemical investigation of the inhibition efficiency of aluminum-tripolyphosphate (ATPP) incorporated in silica (SiO2) and chitosan (Chit) coatings prepared on zinc substrates. Coatings were prepared by dip-coating method. Electrochemical characterization of the coatings was performed by using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization curves (PDP). Effect of ATPP on Zn was also determined in 0.2g/L Na2SO4 solution and its adsorption on zinc was studied. Results concluded that the ATPP adsorption on Zn obeys Langmuir isotherm. The best corrosion resistance was reached when Zn was protected by SiO2 coating, obtained from a precursor sol containing 10-3 M ATPP. Keywords: zinc; silicon dioxide; chitosan; Al-tripolyphosphate; anti-corrosion coating; adsorption. |
