开发了一种新型环境友好型N-烷基-N-脂肪酰基氨基脂肪酸盐（TS-417）无磷缓蚀剂。采用极化曲线和电化学阻抗谱方法研究了TS一417对低碳钢在模拟中碱中硬循环冷却水中的缓蚀作用。结果表明：TS-417缓蚀剂对碳钢具有良好的缓蚀作用，属于阳极抑制型缓蚀剂；其缓蚀效率随着缓蚀剂浓度的增大而增大，当添加浓度为100mg／L时，缓蚀剂效率即可达到90％。

A new "green" corrosion inhibitor named N-alkyl-N-fatty acylamino fatty acid salt (TS-417) was synthesized and characterized. The corrosion inhibition performance of TS-417 on low carbon steel in simulated circulation cooling water conditions was studied by polarization curves, electrochemical impedance spectroscopy (EIS). The results show that the new fatty amide derivative inhibitor TS-417 was a good corrosion inhibitor for low carbon steel, which behaved as a type of anodic inhibitor. The inhibition efficiency increases with the TS-417 concentration increased, which can attain 90 % at 100 mg/L.
