Abstract

The corrosion inhibition characteristics of 1-butyl-3-methylimidazolium chloride ([BMIM][Cl]) ionic liquid (IL) on
Al-Si-Ti based alloy (AA) immersed in 1 M KOH solution were investigated at different solution temperatures of 303
- 343 K, inhibitor concentrations of 0.2 - 1.0 g/L and maximum immersion time of 3 hrs. using electrochemical (EIS),
potentiodynamic polarization (PDP) and thermometric methods, respectively.
