ELECTROCHEMICAL STUDY OF INHIBITIOR ON ALUMINIUM ALLOY IN HIGH CONCENTRATION CHLORIDE SOLUTIONS

Effects of inhibitor concentration and temperature on corrosion of Y112 aluminium alloy in high concentration chloride solutions were studied with electrochemical methods.The inhibition effectivity was changed with the inhibitor concentration.The corrosion potential and rate were related to inhibitor concentration.The corrosion rate increased and inhibition effectivity decreased with temperature rise.
