Abstract: The synergistic inhibition effect between cinnamaldehyde and 3methy4amino5mercapto1,2,4triazole(short for MACMT)on Q235 steel in the HCl solution was studied by polarization curves, EIS and immersion. The influence of concentration on the corrosion performance and inhibition mechanism was discussed. The experiments show that when both cinnamaldehyde and 3methy4amino5mercapto1,2,4triazole were 1 mmol/L inhibiting system proposed good synergistic effect, inhibition efficiency could improve to more than 93%, on the Q235 steel in 0.5 mol/L HCl, 1 mol/L HCl, 2 mol/L HCl solution. In addition, increasing temperature exerted small influence on the inhibition efficiency.

摘要: 分别采用极化曲线、交流阻抗和静态失重等方法研究了肉桂醛与3-甲基-4-氨基-5-巯基-1,2,4-均三唑(简称为MACMT)复配对Q235碳钢在不同浓度盐酸介质中的缓蚀效果。并探讨了缓蚀剂浓度对缓蚀性能的影响及其缓蚀机理。结果表明,肉桂醛与3-甲基-4-氨基-5-巯基-1,2,4-均三唑均为1mmol/L时对Q235碳钢在0.5、1、2mol/LHCl介质中均有很好的缓蚀效果,缓蚀率达93%以上,两者复合后有良好的协同效应。盐酸介质温度的升高对缓蚀性能影响较小。
