      • Abstract
    • The corrosion inhibition effects of EDTA-2Na(C10H14N2O8Na2),diethylamino ethanol((C2H5)2NCH2CH2OH),calcium gluconate((C2H5)2NCH2CH2OH) and disodium hydrogen phosphate(Na2HPO4) on mild steel were investigated in 3.5% NaCl solution at 298K by using potentiodynamic polarization,electrochemical impedance spectroscopy(EIS) and SEM methods.The results showed that all the inhibitors are anodic type inhibitors,the inhibitive efficiency followed the order: Na2HPO4>Ca(C6H11O7)2>C10H14N2O8Na2>(C2H5)2NCH2CH2OH.The inhibitors could be adsorbed on mild steel to inhibit corrosion effectively.
