| 摘 要： | 应用极化曲线、电化学阻抗谱等测试技术,研究了以谷氨酸作缓蚀剂在10%盐酸介质中对X65钢的缓蚀作用,测试腐蚀参数包括腐蚀电位(Ecorr)、极化电阻(Rp)、缓蚀效率(η)等.研究表明:该缓蚀剂是一种抑制阴极为主的混合型缓蚀剂,在较低的浓度具有良好缓蚀效果;缓蚀效率随着浓度的增加而提高,并在0.3g.L-1时达到最大值(90%以上). |

| Abstract: | The inhibition effect of glutamic acid towards the corrosion of X65 steel in hydrochloric acid solution(10%) was investigated using polarization techniques、electrochemical impedance spectroscopy(EIS) and SEM.The corrosion rate,corrosion potential(Ecoor),polarization resistance(Rp) and inhibition efficiency(η) were determined.The results revealed that the inhibitor is a mixed type inhibitor.It has promising corrosion inhibition efficiency at low concentrations.The inhibition efficiency(η) increased with increasing the concentration.The maximum inhibition efficiency appeared at 0.3 g·L-1. |
| Keywords: | corrosion inhibitor glutamic acid hydrochloric acid EIS |
