Abstract This work presents the first corrosion analysis of 4-methyl-2-phenylimidazole (MePhI) corrosion inhibitor for brass immersed in 3 wt.% NaCl solution, wherein MePhI was shown to be highly effective. The structure of the surface layer, the formation of an organo-metallic complex, the spatial distribution of MePhI, and the thermal stability of the MePhI surface layer were described in detail using time-of-flight secondary ion mass spectrometry analysis and X-ray photoelectron spectroscopy. A gas cluster ion beam source using different sizes and accelerating energies of the clusters was also employed to slowly sputter the organic surface layer associated with the surface layer analysis.

4-甲基-2-苯基咪唑作为黄铜腐蚀抑制剂的电化学、3D 形貌、XPS 和 ToF-SIMS 分析

摘要 本工作首次对浸在 3 wt.% NaCl 溶液中的黄铜腐蚀抑制剂 4-甲基-2-苯基咪唑 (MePhI) 进行腐蚀分析，结果表明 MePhI 非常有效。使用飞行时间二次离子质谱分析和 X 射线详细描述了表面层的结构、有机金属配合物的形成、MePhI 的空间分布和 MePhI 表面层的热稳定性光电子能谱。还采用使用不同尺寸和团簇加速能量的气体团簇离子束源缓慢溅射与表面层分析相关的有机表面层。
