| 摘 要： | 通过极化曲线探讨苯骈三氮唑对碳钢在溴化锂溶液中的缓蚀作用，用扫描电镜观察形成的表面膜形态，用红外光谱探讨表面膜的组成。实验表明，苯骈三氮唑对碳钢在溴化锂溶液中有一定的缓蚀作用，其中添加0．020mol／L苯骈三氮唑和0．20mol／L氢氧化锂显抑制溴化锂溶液对碳钢的腐蚀，其可能是在碳钢表面形成Fe-BTA吸附膜，阻滞阳极反应从而起到缓蚀作用。

| Abstract: | The inhibition effect of benzotriazole to carbon steel in lithium bromide solution was studied by polarization curve , meanwhile it studied the form of the film on the carbon steel by SEM and the structure of the film by IR. It revealed that benzotriazole exists inhibition to the carbon steel in the lithium bromide , it decreases effectively the corrosion of the lithium bromide to the carbon steel by adding 0.20 mol/L lithium hydroxide and 0.02 mol/L benzotriazole .It assumed that the complex film of Fe-BTA formed on the carbon steel decrease the corrosion through inhibition of anodic reaction. |
