Abstract

The effect of the zeolite-phosphate anti-corrosion pigment obtained by the mechanoche­mical method on the protective properties of the epoxy coating on carbon steel was inves­tigated. Using the methods of electrochemical impedance spectroscopy, optical 3D profi­lometry, and tests in a heat and humidity chamber, it was established that the addition of such a pigment to an epoxy primer provides a significant reduction in underfilm corrosion of metal.
