    应用电化学方法评价了在饱和CO2模拟盐水中对咪唑啉季铵盐和烷基磷酸酯抑制 A3碳钢腐蚀的效果,并考察了二者复配使用时的协同效应.结果表明,当二者比例为 1∶〖KG-*21,缓蚀率比单独使用时提高了20%以上.咪唑啉季铵盐主要抑制由于阴极反应引起的腐蚀,烷基磷酸酯主要抑制阳极反应引起的腐蚀,复配使用可同时抑制阴、阳极反应引起的腐蚀,缓蚀效果更好.

   The inhibition effect of imidazoline quaternary-ammonium-salt and alkyl-phosphate ester respectively and the synergism of the two chemicals on corrosion of carbon stee1 A3 in a CO2-saturated artificial brine were investigated by electrochemical method.The results indicated that a appreciable positive synergistic effect could be seen when imidazoline quaternary-ammonium-salt and alkyl-phosphate ester were used together with a proportion of 11.In comparison with any individual inhibitor of the two,the corrosion inhibition efficiency for carbon steel A3 could be increased by 20% due to the combination use of them.Imidazoline quaternary-ammonium-salt could mainly inhibit the corrosion caused by cathode reaction,while alkyl-phosphate ester could mainly inhibit the corrosion caused by anode reaction.The two corrosion processes induced by cathode and anode reactions could be effectively inhibited by the combination use of imidazoline quaternary-ammonium-salt and alkyl-phosphate ester.
