Abstract  

The inhibition effect of Brönsted acid ionic liquids (BAIL) 1-methyl-3-(4-sulfonic acid) butyl imidazolium hydrogen sulfate ([(CH2)4SO3HMIm][HSO4]) on the corrosion of Q235 steel in 0.5 mol/L HCl solution was investigated by electrochemical measurements. The results showed that the BAIL could suppress the corrosion process of Q235 steel in HCl solution at 25 ℃ through adsorption. The inhibition efficiency increased with the increasing concentration of BAIL in the range 0~14 mmol/L, but decreased with the increasing concentration of BAIL in the range 14~16 mmol/L. The best inhibition efficiency was 80.7% for the solution with 14 mmol/L BAIL. The potentiodynamic polarization curves revealed that the BAIL could act as a mixed-type inhibitor. SEM observation of Q235 surface showed that the adsorption of inhibitor molecules on Q235 surface could form a film of BAIL, and which could prevent both the hydrogen evolution and iron dissolution. This inhibition mechanism was proved further by the results of XPS analysis.
