Abstract

Zinc-iron (ZnFe) alloy was deposited on carbon steel (CS) by chronopotentiometry technique, in acidic medium. Then, poly(pyrrole-co-N-methylaniline) film was synthesized from 0.02 M pyrrole + 0.02 M N-methylaniline containing 0.3 M oxalic acid medium. The synthesis was achieved on ZnFe alloy plated carbon steel (CS/ZnFe) by using cyclic voltammetry technique. Poly (pyrrole-co-N-methylaniline) film was characterized by linear sweep voltammetry, potentiodynamics polarization and electrochemical impedance spectroscopy methods. Nyquist curves have shown that the poly(pyrrole-co-N-methylaniline) film has high polarization resistance by exhibiting electrocatalytic effect at mid-term exposure times in the corrosive medium. It was observed that the polarization resistance of the copolymer film coated electrode decreased in long-term exposure times.

Özet

ZnFe alaşım, kronopotansiyomeri tekniği ile karbon çelik (CS) yüzeyine asidik ortamda kaplandı. Daha sonra poli(pirol-co-N-metilanilin) film 0.02 M pirol + 0.02 M N-metilanilin içeren 0.3 M okzalik asit ortamında sentezlendi. Seztez ZnFe kaplı karbon çelik (CS/ZnFe) yüzeyine dönüşümlü voltametri tekniği kullanılarak gerçekleştirildi. Poli(pirol-co-N-metilanilin) film doğrusal taramalı voltametri, potansiyodinamik polarizasyon ve elektrokimyasal empedans spektroskopisi yöntemleriyle karakterize edildi. Nyquist diyagramları poli(pirol-co-N-metilanilin) filmin korozif çözeltiye orta-zamanlı daldırma sürelerinde elektrokatalitik etkiye sahip olduğunu gösterdi. Uzun zamanlı daldırma sürelerinde ise kopolimer film kaplı elektrodun polarizasyon direncinde azalma meydana geldiği gözlenmiştir.
