Herein, the protective performance of a new triazole inhibitor for carbon steel was studied by electrochemical methods. Potentiodynamic polarization curves showed that the anti-corrosion efficiency improved with increasing concentrations of the inhibitor and the results show that it is 22 times corrosion resistance efficiency for inhibitor compared to bare aggressive solution. X-ray photoelectron spectroscopy showed that the film adsorbed well on the carbon steel surface. The scanning vibrating electrode technique demonstrated the corrosion process of carbon steel with and without the protection of inhibitor. Thus, a mechanism for the corrosion process was proposed and the behavior of carbon steel under the protection of the inhibitor was discussed.
在此，通过电化学方法研究了一种新型三唑碳钢缓蚀剂的防护性能。动电位极化曲线表明，缓蚀剂浓度增加时，其防腐效率提高，结果显示，与未加缓蚀剂的侵蚀性溶液相比，该缓蚀剂的耐腐蚀效率提高了22倍。X射线光电子能谱表明，该膜在碳钢表面吸附良好。扫描振动电极技术展示了有无缓蚀剂保护时碳钢的腐蚀过程。因此，提出了腐蚀过程的机理，并讨论了碳钢在缓蚀剂保护下的行为。
