This work presents a corrosion study of 2-aminobenzimidazole (ABI) as a corrosion inhibitor for brass in chloride solution. Electrochemical, field emission scanning electron microscopy, atomic force microscopy, and contact angle measurements showed that ABI mitigates brass corrosion after short-, medium-, and long-term immersion periods. Next, a detailed surface analysis of the ABI adsorbed on the brass surface was performed using attenuated total reflectance Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy (XPS), and time-of-flight secondary ion mass spectrometry (ToF-SIMS) techniques. XPS imaging was performed in association with principal component analysis to determine the different phases on the surface. In order to describe the in-depth composition of the ABI surface, an angle-resolved XPS analysis was performed. This analysis was further supported by gas cluster ion beam sputtering to gradually remove the ABI surface layer, and XPS analysis was performed after each sputtering cycle. Finally, TOF-SIMS analyses showed the formation of Cu/Cu₂-ABI and Zn-ABI compounds, the 2D distribution of ABI-related compounds, and their thermal stability on the brass surface.

这项工作提出了2-氨基苯并咪唑（ABI）作为氯化物溶液中黄铜的腐蚀抑制剂的腐蚀研究。电化学，场发射扫描电子显微镜，原子力显微镜和接触角测量结果表明，ABI可以在短期，中期和长期浸泡后减轻黄铜腐蚀。接下来，使用衰减全反射傅里叶变换红外光谱，X射线光电子能谱（XPS）和飞行时间二次离子质谱（ToF-SIMS）技术对吸附在黄铜表面的ABI进行了详细的表面分析。 。XPS成像结合主成分分析来确定表面上的不同相。为了描述ABI表面的深度成分，进行了角度分辨XPS分析。气体团簇离子束溅射进一步支持该分析，以逐渐去除ABI表面层，并在每个溅射周期后进行XPS分析。最后，TOF-SIMS分析表明形成了Cu / Cu₂ -ABI和Zn-ABI化合物，ABI相关化合物的2D分布及其在黄铜表面的热稳定性。
