| 摘 要： | 利用动电位扫描极化曲线、交流阻抗、分光光度计等测试手段研究了在1．0mol／LHCI介质中PhABMT和醋酸钠的复配体系对45号铜的缓蚀协同作用；探讨了温度、预膜时间对缓蚀效率的影响。结果显示，PhABMT与醋酸钠之间存在良好的缓蚀协同作用，0．2g／L PhABMT＋1．2g／L醋酸钠复配后缓蚀剂体系的缓蚀效率可以达到96％左右，复配后缓蚀剂体系的缓蚀效率在75℃的高温条件下仍能达到83％左右，体系的缓蚀效率随在乙醇中预膜时间的增加而增大。

| Abstract: | The inhibition efficiency of the PhABMT and sodium acetate for 45 carbon steel in 1.0 mol/L HCI solution was studied by polarization curve measurement and electrochemical impedance spectroscope and spectrophotometer. The influence of temperature and membrane time on the inhibiter efficiency was investigated. The results showed that a good synergistic effect between PhABMT and sodium acetate is existed. 0. 2g/L PhABMT ＋1.2g/L sodium acetate corrosion inhibitor inhibiting efficiency is about 96% The synergistic effect of PhABMT and sodium acetate corrosion inhibitors is can reach 83% in high temperature condition, and increases with membrane time in ethanol. |
