The inhibition effect
of 5-(4-Dimethylaminobenzyliden)-rhodanin (D-Rh) molecule on mild steel
corrosion has been investigated in 0.5 M H₂SO₄ solution
using help with electrochemical impedance spectroscopy, linear polarization
resistance, chronoamperometry and potentiodynamic polarization techniques. The
experimental result show that the inhibitor efficiency increases with
increasing inhibitor concentration. The adsorption isotherm is suitable with
Langmuir. The Ea are calculated.

YUMUŞAK ÇELİĞİN ASİDİK ORTAMDAKİ KOROZYON DAVRANIŞINA 5-(4-Dimetilaminobenzyliden)-rodanin MOLEKÜLÜNÜN ETKİSİ

Öz

5-(4-Dimetilaminobenzyliden)-rodanin (D-Rh) molekülünün, yumuşak çeliğin
korozyonuna inhibisyon etkisi 0,5 M H₂SO₄ çözeltisinde,
elektrokimyasal impedans spektroskopisi, lineer polarizasyon direnci,
kronoamperimetri ve potansiyodinamik polarizasyon eğrilerinden yararlanılarak
araştırılmıştır. Deneysel sonuçlar inhbisyon etkinliğinin D-Rh’ın derişimi ile
artığını göstermiştir. Adsorpsiyon izotermi Langmuir adsorpsiyon izotermine
uymaktadır.  D-Rh molekülü için
aktivasyon enerjisi hesaplanmıştır.
