亚油酸缓蚀剂缓蚀机理的研究

Study of Inhibited Mechanism of Linoleic Acid Inhibitor

利用动电位扫描和交流阻抗法等,测定了脂肪酸对45钢的缓蚀能力。实验测得界面电阻(R_p)和亚油酸浓度(C_L)之间存在对数关系:R_p=A+B logC_L。脂肪酸的优良缓蚀能力,在于脂肪酸容易在金属表面上的吸附,有效地阻止了腐蚀介质与金属的作用。

This paper has measured inhibiting capability of fatty acid for 45 stell by impedance method and cyclic votlammetry. Under certain condition, interface resistance R_p has logarithmic R_p = A+B logC_L relation to concentration of linoleic acid C_L. The fine inhibiting capability of linoleic salts, because it is adsorbed on the surface of metal, it inhibites the effect of corrosive metallic on melafllic surface.
