Effects of Different Inhibitors on Corrosion of Mild Steel in 3.5% NaCl Solution
摘 要
采用动电位极化曲线、交流阻抗和扫描电镜法研究了乙二胺四乙酸二钠、二乙胺基乙醇、葡萄糖酸钙、磷酸氢二钠在3.5% NaCl溶液中对A3碳钢的缓蚀作用.研究结果表明,四种缓蚀剂均为阳极型缓蚀剂,缓蚀效果为:磷酸氢二钠＞乙二胺四乙酸二钠＞葡萄糖酸钙＞二乙胺基乙醇.

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.
