摘要:

采用电化学方法,系统的研究了动态条件下,3% (质量分数) NaCl腐蚀介质中,十二胺缓蚀剂对Q235碳钢CO₂腐蚀的缓蚀行为。结果表明,静态条件下,十二胺对碳钢CO₂腐蚀具有较好的缓蚀效果,当缓蚀剂浓度为60 mg/L时,缓蚀效率可以达到93.44%。动态条件下,无缓蚀剂的测试介质中,试样的腐蚀速率随着转速的增加而增加。在含有80 mg/L十二胺缓蚀剂测试介质中,试样在转速为500 r/min时的腐蚀速率最大;而在2000 r/min时,试样的腐蚀速率最小,缓蚀剂的加入明显的改变了试样的腐蚀行为。转速为1500 r/min时,试样的腐蚀速率随着缓蚀剂浓度的增加而减少;当缓蚀剂浓度为80 mg/L时,缓蚀效率可以达到87.93%。

Abstract：

The corrosion inhibition of dodecylamine on carbon steel in NaCl solution with continuous aeration of CO₂ was studied by means of a rotating disk with electrochemical methods. Results show that the inhibition efficiency of dodecylamine can reach 93.44% with the inhibitor dose of 60 mg/L in the solution. In the blank NaCl solution without inhibitor, the corrosion rate of the steel increases with the increase of the rotation speed. In the solution with the inhibitor dose of 80 mg/L, the corrosion rate of the steel reaches the highest by rotation speed 500 r/min, and then the lowest by 2000 r/min. The corrosion behavior of carbon steel has changed obviously in the presence of inhibitor. The corrosion rate increases with the increase of inhibitor dose, and the inhibition efficiency can reach 87.93% in the presence of inhibitor dose of 80 mg/L by 1500 r/min.
