Influence of Three Proton Acid Ionic Liquids on Corrosion Behavior of Q235 Steel
The corrosion behavior of Q235 steel in three proton acid ionic liquids with different cations,i.e.3-methyl-l-(4-sulfonic acid) butyl imidazolium hydrogen sulfate [(CH2)4SO3HMIm][HSO4](IL1),N-(4-sulfonic acid) butylpyridinium hydrogen sulfate [(CH2)4SO3HPy][HSO4](IL2) and N-(4-sulfonic acid) butyl triethylammonium hydrogen sulfate) [(CH2)4SO3HTEA][HSO4](IL3) were studied.The surface morphology and compositions of the corrosion products were examined by scanning electron microscopy(SEM).The results revealed that the Q235 steel exhibited rather good resistance to these liquids and its corrosion rates increased with the increasing temperature.Corrosion resistance of Q235 steel in the three ionic liquids decreases according to an order as follows:IL3IL23IL1,and finally the electrochemical corrosion mechanism is also proposed.
