摘要:
本文采用动电位极化、线性极化、电偶电流和高压釜挂片失重等法,研究了含氮、硫有机缓蚀剂和/或Me2+对X60钢在CO2饱和的盐水溶液中的缓蚀作用。结果表明,含氮、硫的有机缓蚀剂在缓蚀过程中,开始是以抑制阳极过程为主,随后是以抑制阴极过程为主的混合型缓蚀剂。如与Me2+复配使用,能明显地提高缓蚀效能。

THE INHIBITION OF THE X60 STEEL IN CO2 SATURATED SALTY WATER
Abstract:
The influence of the organic compound consisting of nitrogen and sulphur or/and Me2+ ions on the inhibition of the X60 steel in CO2 saturated salty water was studied. The results show that the organic compound consisting of nitrogen and sulphur first inhibits mainly the anodic process, and then the cathodic process. It is an inhibitor of the mixed type. If a combination organic inhibitor and Me2+ was applied to test solution, the ingibiting efficiency could be raised. The inhibition exhibits a synergistic effect. The ingibitive mechanisms are also discussed.
