前言对于水中Cl~-对碳钢腐蚀的影响和缓蚀剂的研究,已有不少报道,但因在高Cl~-浓度下缓蚀效果较差,或因使用浓度过高和具有毒性及来源等的限制而无实用价值。Cl~-对金属表面形成缓蚀膜层的影响的研究。也有一些报道,但对其作用机理尚不清楚。本文研究了PC-602缓蚀剂在不同Cl~-含量的水溶液中对碳钢的缓蚀作用;用AES分析研究了Cl~-对缓蚀剂成膜的影响;用恒电位极化曲线法测定了Cl~1浓度对电化学过程的影响。
Preface There have been many reports on the effect of Cl ~ - on the corrosion of carbon steel in water and the study of corrosion inhibitors. However, due to the poor corrosion inhibition effect under high Cl ~ - concentration or due to the use of high concentration and toxicity and sources Other restrictions without practical value. Effect of Cl ~ - on Corrosion Inhibition Layer on Metal Surface. There are some reports, but its mechanism of action is not yet clear. In this paper, the corrosion inhibition effect of PC-602 corrosion inhibitor on carbon steel in aqueous solution with different Cl ~ - content was studied. The effect of Cl ~ - on corrosion inhibition was studied by AES analysis. The effect of Cl ~ 1 concentration on the electrochemical process was measured.
