1-Benzil-3-Metilimidazolyum Hekzaflorofosfat’ın Asidik Ortamda C1010 Çeliğin Korozyonuna Etkisi

Bu çalışmada, C1010 çeliğin 1 M HCl çözeltisindeki korozyonuna 1-benzil-3-metilimidazolyum hekzaflorofosfat’ın inhibisyon etkinliği çalışılmıştır. Elektrokimyasal impedans spektroskopi (EIS) ve potansiyodinamik polarizasyon teknikleri kullanılmıştır. Potansiyodinamik polarizasyon sonuçları, anodik ve katodik akım yoğunluklarının inhibitör derişiminin artması ile azaldığını göstermiştir. EIS ölçümlerinden ise artan sıcaklıklarda dahi inhibisyon etkinliklerinin halen yüksek olduğu belirlenmiştir. İnhibitörün metal üzerindeki adsorpsiyon davranışı, Langmiur adsorpsiyon izotermine uymaktadır. Elde edilen tüm sonuçlar, kullanılan inhibitörün C1010 çeliğin asidik ortamdaki korozyonu üzerine %83,5 inhibisyon etkinliğine sahip olduğu göstermektedir.

The Influence of 1-Benzyl-3-Methylimidazolium Hexafluorophosphate on Corrosion of C1010 Steel in Acidic Medium

In present study, inhibition efficiency of 1-benzyl-3-methylimidazolium hexafluorophosphate was examined in 1 M HCl solution on corrosion of C1010 steel. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization methods were realized. Potentiodynamic polarization results revealed that anodic and cathodic current densities were reduced with increase of inhibitor concentration. It was also determined from EIS measurements inhibition efficiencies were still high even increased temperatures. Adsorption behavior of inhibitor on steel obeyed Langmuir adsorption isotherm. The obtained all results demonstrated that used inhibitor had 83.5% inhibition efficiency on corrosion of C1010 steel in acidic medium.
