通过使用扫描电镜，动电位极化曲线法和交流阻抗法，研究了2-巯基苯并咪唑及其分别与十六烷基三甲基溴化铵和硫脲复配对N80钢在0.5mol/LHCl中的缓蚀性能。针对酸性介质，添加缓蚀剂是最佳的方式。实验结果表明，2-巯基苯并咪唑的加入使得腐蚀电位正移，抑制测量电极阳极的腐蚀过程。而其与十六烷基三甲基溴化铵和硫脲复配后的缓蚀效果优于单独使用2-巯基苯并咪唑的性能。实验可知，十六烷基三甲基溴化铵和硫脲都与2-巯基苯并咪唑产生了明显的协同作用。这一相关研究具有极其重要的实际应用作用。

By using SEM,potentiodynamic polarization curve and ac impedance method,studied 2-mercapto benzene and imidazole alone and respectively with cetyl trimethyl ammonium bromide and thiourea complex matching for N80 steel corrosion performance in 0.5mol/L HCl.In view of the acid medium,adding corrosion inhibitor is the best way.As the results show that addition of 2-mercapto benzen makes the corrosion potential move forward to positve direction,so inhibit measuring anode corrosion process.The corrosion effect of compound with cetyl trimethyl ammonium bromide and thiourea is superior to use 2-mercapto benzene alone.Experiment shows that cetyl trimethyl ammonium bromide and thiourea with 2-mercapto benzene both have a obvious synergy.This research has the extremely important role in practical application.
