The anticorrosion environmentally friendly pigments based on synthetic zeolite for paint coatings were obtained by liquid-phase ion exchange method. Zeolite was modified with zinc, calcium and manganese ions. The corrosion resistance of 09G2C steel in 0.1% NaCl solution and in suspensions of modified zeolite was investigated by potentiodynamic polarization method. It was shown that the use of zeolite modified with cations of divalent metals contributes to the reduction of corrosion currents. It was found that the zeolite modified with zinc cations exhibits the most anticorrosion effect relative to 09G2C steel, as indicated by the values of corrosion currents (which are ~2 times smaller than in the non-inhibited solution) and the results of electrochemical impedance spectroscopy. The surface morphology of 09G2S steel after exposure to the inhibited media was determined by scanning electron microscopy. Protection mechanism of the modified zeolite was suggested.
