Klorürlü Ortamlarda (pH=7,0) Bakırın Korozyon Davranışlarına Askorbik Asidin İnhibisyon Etkisinin Belirlenmesi

Bu çalışmada, bakırın korozyon davranışlarına Askorbik asidin inhibisyon etkisi %3.5 Cl? 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.

Determination Of Inhibition Effects Of Ascorbic Acid On The Corrosion Behavior Of Copper In Chloride Medium (pH=7.0)

In this study, the inhibition effects of Ascorbic acid on copper corrosion behavior in 3.5% Clions solution was investigated using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The current‐potential curves at different concentrations of ascorbic acid and Nyquist curves were obtained. Ascorbic acid with and without scanning of the copper electrode in 3.5% NaCl solution electron microscope (SEM) images of the surface is determined. According to the results of the ascorbic acid prevents the corrosion of copper in 3.5% NaCl solution. The inhibitory efficiency was found to increase with decrease in the ascorbic acid concentration
