The inhibiting behavior of 1-butyl-3-methylimidazolium bromide [BMIM]Br on mild steel corrosion in 1.0 M HCl as corroding solution at 25 °C was evaluated by various corrosion monitoring techniques. The obtained results showed that [BMIM]Br is a good inhibitor for mild steel in 1.0 M HCl solution. Potentiodynamic polarization data indicated that the [BMIM]Br acts essentially as a mixed-type inhibitor. The effect of inhibitor concentration on zero charge potential (ZCP) of the mild steel in 1.0 M HCl was studied and its comparison with OCP has been made for evaluation of the mechanism of adsorption of [BMIm]+ cation. The effect of temperature on corrosion behavior of mild steel in 1.0 M HCl with addition of [BMIM]Br was studied in the temperature range of 25–45 °C. The inhibition efficiency decreases with the rise of temperature.
