Abstract :
the corrosion inhibition efficiency of (3-(4-chlorophenyl isoxazole-5-yl) methanol (cpim) and (3-(2,4 dichlorophenolisoxazole-5-yl) methanol (dcpim) for mild steel in 1 m hcl has been studied using electrochemical methods at 40 and 50 °c. polarization studies showed that the inhibitors are efficient mixed-type corrosion inhibitors, and their inhibition performance increased with the rise of inhibitor concentration and decrease of temperature. the result of eis measurements was analyzed through an appropriate equivalent circuit model to model the corrosion inhibition.
Keywords :
