Effect of Zeolite-Phosphate Anti-Corrosion Pigment on Protective Properties of Epoxy Coating on Carbon Steel
摘要
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. Methods of electrochemical impedance spectroscopy, optical 3D profilometry, and tests in a heat and humidity chamber established that adding such a pigment to an epoxy primer significantly reduces the rate of the metal under-film corrosion.
