Abstract
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.

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.
