Abstract The inhibitive effects provided by benzotriazole (BTA) and cerium chloride (CeCl3) on 2024-T3 aluminium alloy were assessed, individually and combined, in 0.05 M NaCl electrolytes, by means of Electrochemical Impedance Spectroscopy (EIS). From the analysis of impedance fitted parameters, a synergistic effect appears to exist between both inhibitors until 14 days of immersion. The Scanning Vibrating Electrode Technique (SVET) was applied to an Al/Cu galvanic coupling model in order to better comprehend the observed inhibitive actions. Additionally, Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS) was employed to evaluate the in-depth distribution of species related to the inhibitive film/alloy interface.

苯并三唑和氯化铈作为 AA2024-T3 的缓蚀剂：一项由 SVET 和 ToF-SIMS 分析支持的 EIS 研究

摘要 在 0.05 M NaCl 电解质中，通过电化学阻抗谱 (EIS) 评估了苯并三唑 (BTA) 和氯化铈 (CeCl3) 对 2024-T3 铝合金的抑制作用。从阻抗拟合参数的分析来看，两种抑制剂之间似乎存在协同效应，直到浸泡 14 天。为了更好地理解观察到的抑制作用，将扫描振动电极技术 (SVET) 应用于 Al/Cu 电偶耦合模型。此外，飞行时间二次离子质谱 (ToF-SIMS) 用于评估与抑制膜/合金界面相关的物种的深度分布。
