The Effects of Ferula (Ferula elaeochytris K.) to Electrochemical Behaviour of Mild Steel in Chloride Medium

Öz

In this study, the effect of Ferula in the electrochemical behaviour of mild steel has been investigated in 3.5% NaCl solution (pH=8.5) using electrochemical impedance spectroscopy (EIS). Nyquist and Bode diagrams were obtained in different concentrations of Ferula. The surface morphology of the mild steel was examined by scanning electron microscopy. The obtained results show that, Ferula inhibits corrosion of mild steel in 3.5% NaCl solution. It has been found that the efficiency of the inhibition is changed by the concentration of the Ferula extract.

Klorürlü Ortamda Yumuşak Çeliğin Elektrokimyasal Davranışlarına Çakşır (Ferula Elaeochytris K.) Özütünün İnhibisyon Etkisinin Belirlenmesi

Öz

Bu çalışmada, yumuşak çeliğin elektrokimyasal davranışlarına çakşır (Ferula elaeochytris K.) ekstraktının inhibisyon etkisi, %3,5 NaCl çözeltisinde (pH=8,5) ve elektrokimyasal impedans spektroskopisi (EIS) kullanılarak araştırılmıştır. Çakşır ekstraktının farklı derişimlerde Nyquist ve Bode diyagramları elde edilmiştir. Yumuşak çeliğin yüzey morfolojileri taramalı elektron mikroskobu ile görüntülenmiştir. Elde edilen sonuçlardan çakşır ekstraktı, %3,5 NaCl çözeltisinde yumuşak çeliğin korozyonunu azaltmaktadır. İnhibisyon etkinliğinin, çakşır ekstraktının derişimi ile değiştiği tespit edilmiştir.
