Anticorrosion performance of epoxy coatings on steel surface exposed to deionised water
Abstract
The objective of this work was to examine the anticorrosive behaviour of four different epoxy coatings, which were formulated with zinc pigments and were applied on pretreated steel panels exposed to deionised/deaerated water taken from the installations of the Greek Public Electricity Company, as well as to compare the results of this study with those of a relevant, previous work. The coating's performance was assessed by the measurement of the potentiodynamic polarisation resistance, by electrochemical impedance spectroscopy and the measurement of dielectric permittivity, during the deionised/deaerated water immersion tests. Additionally, accelerated salt spray tests were performed. All types of coatings tested exhibited a high protective performance. It was concluded that the epoxy system containing zinc dust was the most effective anticorrosion coating under the conditions relevant to this study.
