Abstract: (274 Views)
Anti-corrosion coatings based on the epoxy resin belnding with different extenders including talc, silicon dioxide
and barium sulfate were prepared and applied on the carbon steel surface. The corrosion behavior of these coating
systems versus the immersion time in 1M sulfuric acid was investigated by using electrochemical impedance
spectroscopy (EIS) method. The anti-corrosion behavior of the coatings was simulated using EIS data and the
approperiate equivalent circuit models. Variation of the coating and double layer parameters showed that the
protective strenght of the epoxy coating blending with different extenders against corrosion is as the following
sequence: Talc > Silicon dioxide > without extender > Barium sulfate
