【摘要】 采用电化学方法和原子力显微镜研究了阳离子缓蚀剂(咪唑啉衍生物)对电偶腐蚀的抑制作用,并探讨了其作用机理。结果表明,在耦合前阳离子缓蚀剂吸附仅吸附在碳钢表面,耦合后缓蚀剂分子在偶对的阴极(不锈钢)和阳极(碳钢)表面均有吸附,其在阳极区域的覆盖度较之耦合前减小,缓蚀作用减弱。更多还原

【Abstract】 The inhibition behavior of imidazoline derivative as an anodic ion inhibitorfor galvanic Corrosion was studied by using electrochemical methods and atomic force microscopy (AFM) technology. The results show that anodic ion inhibitor adsorbs to the surface of carbon steel while it does not adsorb to stainless steel when the single metal immersed in the solution containing the inhibitor. When the two metals galvanicly coupled, the molecules of the inhibitor can adsorb to the surface of both carbon steel and stainless steel. However, in this case, the inhibitor coverage on the surface of carbon steel decreased compared with that on single carbon steel, and the adsorbability between inhibitor and surface of carbon steel weakened.更多还原
