| 摘 要： | 应用极化曲线法和电化学阻抗技术,考察了十二烷基肌氨酸钠对模拟混凝土孔隙液中钢筋的缓蚀作用.结果表明,十二烷基肌氨酸钠对在含氯离子的模拟混凝土孔隙液中的钢筋有良好的缓蚀效果.极化曲线和电化学阻抗谱的测试结果一致证实十二烷基肌氨酸钠的加入量为100mg/L时,对含0.6mol/L NaCl的模拟混凝土孔隙液中钢筋的缓蚀效果最好.

| Abstract: | The linear polarization and electrochemical impedance spectroscopy were used to study the corrosion inhibition of N-lauroyl sarcosine sodium on reinforcing steel in simulated concrete pore solution with chloride ions.The results showed that N-lauroyl sarcosine sodium had a good effect on the reinforcing steel,and the presence of 100mg/L N-lauroyl sarcosine sodium had a best inhibition effect on reinforcing steel in simulated concrete pore solution with 0.6mol/L NaCl under the experimental conditions in this... |
