The anodic dissolution behaviors of aluminum in AlCl₃-[BzMIM]Cl (1-benzyl-3-methylimidazolium chloride) ionic liquid was investigated using coulometric weight loss experiments, linear sweep voltammetry, potentiodynamic polarization and electrochemical impedance spectroscopy. The results showed that passivation occurred during the anodic dissolution of aluminum, and the passivation film was identified as the formation of AlCl₃ precipitates and local solidification of electrolyte on the electrode surface. The potentiodynamic polarization analysis showed that an increase in temperature caused a positive shift in corrosion potential (E_corr), an increase in corrosion current density (i_corr) and a decrease in polarisation resistance (R_P). Impedance measurements indicated that the anodic dissolution process of aluminum in AlCl₃-[BzMIM]Cl ionic liquids consisted of charge transfer, confinement of the passivated film on the electrode surface and diffusion-induced Warburg impedance.

使用库仑失重实验、线性扫描伏安法、动电位极化和电化学阻抗谱研究了铝在 AlCl ₃ -[BzMIM]Cl（1-苄基-3-甲基咪唑氯化物）离子液体中的阳极溶解行为。结果表明，铝在阳极溶解过程中发生钝化，钝化膜被鉴定为在电极表面形成AlCl ₃沉淀物和电解质局部凝固。动电位极化分析表明，温度升高导致腐蚀电位正移（E _corr），腐蚀电流密度增加（i _corr），并在极化电阻（下降- [R _P）。阻抗测量表明铝在 AlCl ₃ -[BzMIM]Cl 离子液体中的阳极溶解过程包括电荷转移、钝化膜在电极表面的限制和扩散引起的 Warburg 阻抗。
