Corrosion inhibition of aluminium and steel by imidazolium salts
Original language description
The corrosion inhibition of aluminium and steel in the hydrochloric acid solution by 1-octyl-3-methylimidazolium bromide, 1-octyl-3-methylimidazolium hydrogensulphate and 1-dodecyl-3-methylimidazolium bromide was investigated using electrochemical and weight loss methods. The qualitative surface analysis was carried out. All the imidazolium salts under investigation act as mixed type inhibitors with predominantly cathodic action on aluminium and predominantly anodic action on steel. The inhibition efficiency of 1-octyl-3-methylimidazolium hydrogensulphate was higher than 99 % for aluminium but decreased with time rapidly. The surface analysis elucidated the differences between the inhibition action on the mild and stainless steel. The Gibbs energy of adsorption was calculated by means of the Langmuir isotherm.
