Abstract

In this study, the effect of Ascorbic acid in the corrosion behaviour of copper has been investigated in 3.5% NaCl solution (pH=9.0) using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Current-potential curve and Nyquist diagrams were obtained in different concentrations of ascorbic acid. The surface morphology of copper after their exposure to 3.5% NaCl solution with and without of ascorbic acid was examined by scanning electron microscopy (SEM). The obtained results show that, ascorbic acid inhibits corrosion of copper in 3.5% NaCl solution. Inhibition activity was determined to increase with decrease in the concentration of ascorbic acid.

Özet

Bu çalışmada, bakırın korozyon davranışlarına askorbik asidin etkisi %3.5 NaCl çözeltisinde (pH=9.0) potansiyodinamik polarizasyon ve elektrokimyasal impedans spektroskopisi kullanılarak araştırılmıştır. Askorbik asidin farklı derişimlerde akım-potansiyel eğrileri ve Nyquist eğrileri elde edilmiştir. Askorbik asit içeren ve içermeyen %3.5 NaCI çözeltilerinde bekletildikten sonra bakır elektrotun taramalı elektron mikroskopu (SEM) ile yüzey görüntüleri kaydedilmiştir. Elde edilen sonuçlardan askorbik asit %3.5 NaCl çözeltisinde bakırın korozyonunu engellemektedir. İnhibisyon etkinliğinin askorbik asit konsantrasyonundaki azalma ile arttığı tespit edilmiştir.
