The inhibiting behavior of 1-butyl-3-methylimidazolium bromide [BMIM]Br on mild steel corrosion in 1.0M 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 1.0MHCl 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 1.0MHClwas 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 1.0M 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.
