摘要：

The effect of complex zeolite-phosphate anti-corrosion pigment obtained by mechanochemical modification of synthetic zeolite with calcium cations followed by liquid-phase deposition of zinc-phosphate phase on the protective properties of epoxy coating on aluminum alloy was investigated. The methods of electrochemical impedance spectroscopy, optical 3D profilometry, and tests in a humidity and heat chamber established that adding such pigment to an epoxy coating significantly increases its anti-corrosion properties. As a result, the metal charge transfer resistance increases, and the amount of corrosion products in the sites of defects in the paint layer decreases.
