Bu çalışmada, bakırın korozyon davranışlarına Askorbik asidin inhibisyon etkisi %3.5 iyonu içeren

ortamlarda potansiyodinamik polarizasyon ve elektrokimyasal impedans spektroskopisi (EIS)

kullanılarak araştırılmıştır. Askorbik asidin farklı derişimlerde akım-potansiyel ve Nyquist eğrileri elde

edilmiştir. Askorbik asit içeren ve içermeyen %3.5 NaCI çözeltilerinde bakır elektrotun taramalı elektron

mikroskopu (SEM) ile yüzey görüntüleri belirlenmiştir. Elde edilen sonuçlara göre, Askorbik asit %3.5

NaCl çözeltisinde bakırın korozyonunu engellemektedir. İnhibisyon etkinliğinin askorbik asit

konsantrasyonundaki azalma ile arttığı tespit edilmiştir.
