The electrochemical behaviour of a carbon steel in deaerated acid media with concentrations of 20 ppm, 50 ppm, 100 ppm and 200 ppm imidazoline at different temperatures and with different stirring rates has been evaluated by using anodic and cathodic polarization curves (Tafel) and electrochemical impedance spectroscopy (EIS) to compare the corrosion inhibition efficiency. The experimental results suggest that imidazoline is a good corrosion inhibitor at 50 ppm concentration.


Das elektrochemische Verhalten von Kohlenstoffstahl in sauerstofffreien Medien in Anwesenheit von jeweils 20 ppm, 50 ppm, 100 ppm und 200 ppm Imidazolin wurde bei verschiedenen Temperaturen und Rührgeschwindigkeiten mittels anodischer und kathodischer Polarisationskurven (Tafel) sowie elektrochemischer Impedanzspektroskopie untersucht, um die Effizienz des Inhibitors zu evaluieren. Die experimentellen Ergebnisse zeigen, dass Imidazolin mit einer Konzentration von 50 ppm ein guter Korrosionsinhibitor ist.
