Ionic liquids (il) corrosion on a285 carbon steel

In this work, corrosion caused by different ionic liquids on Grade A – A285 carbon steel plates at room temperature (25°C) is studied. Ionic liquids were prepared via acid – base neutralization. The ionic liquid hydrophilic or hydrophobic character was determined by the wettability technique. Corros...

Description
Summary:In this work, corrosion caused by different ionic liquids on Grade A – A285 carbon steel plates at room temperature (25°C) is studied. Ionic liquids were prepared via acid – base neutralization. The ionic liquid hydrophilic or hydrophobic character was determined by the wettability technique. Corrosion behavior for each system was analyzed by electrochemical measurements (open circuit potential monitoring and potentiodynamic polarization). Substrate morphology was analyzed by scanning electron microscope and energy dispersive X-ray spectroscopy before and after the electrochemical measurements. The results obtained showed that Grade A – A285 carbon steel in contact with the ionic liquids presented low corrosion rates, being the highest one the corresponding for the 2- hydroxyethylamominum lactate system and the lowest corrosion rate for 2-hydroxyethylammonium acetate system.
