Protic ionic liquids (PILs) have shown to be promising substances as corrosion inhibitors (CIs). In line with this, the aim of this study is to study the performance and propose the corrosion inhibition mechanism of N‐methyl‐2‐hydroxyethylamine (M‐2HEAOL) and bis‐2‐hidroxyethylamine (B‐HEAOL) oleate, for mild steel, in a neutral chloride solution. Electrochemical characterization was conducted under static and hydrodynamic conditions, and it was revealed that M‐2HEAOL and B‐HEAOL worked as mixed‐type CIs with more interference on the anodic reaction. Inhibition efficiency depended on the concentration reaching 97% of inhibition efficiency in 5 mmol/L concentration. Scanning electron microscopy, optical interferometry, Raman spectroscopy, and Fourier‐transform infrared spectroscopy are used to elicit the chemical composition of the surface film and corrosion morphology of steel in the presence of CIs, the adsorption processes of which involved physical and chemical adsorption between metal and different parts of ionic liquids. The results allowed the proposition of a corrosion inhibition mechanism.

一种基于氨基的质子离子液体，可作为低碳钢在氯化物水溶液中的腐蚀抑制剂
质子离子液体（PIL）已显示出作为腐蚀抑制剂（CI）的有前途的物质。为此，本研究的目的是研究氮的性能并提出缓蚀机理。甲基-2-羟乙基胺（M-2HEAOL）和双-2-羟羟乙胺（B-HEAOL）油酸酯，用于中性氯化物溶液中的低碳钢。电化学表征是在静态和流体动力学条件下进行的，结果表明M-2HEAOL和B-HEAOL是混合型CI，对阳极反应的干扰更大。抑制效率取决于浓度在5 mmol / L浓度下达到抑制效率的97％。在存在CI的情况下，使用扫描电子显微镜，光学干涉仪，拉曼光谱和傅里叶变换红外光谱来得出钢的表面膜化学成分和腐蚀形态，其吸附过程涉及金属之间的物理和化学吸附以及离子液体的不同部分。
