Abstract

The effect of a salicylaldimine Schijf base (l,4-Bis[2-(2-hydroxybenzyliden amino) phenoxyjbutane) on the coirosion behaviour of mild steel in 0.1M HCl media were investigated by using potentiodynamic polarisation, linear polai'isation, electi'ochemical impedance spectroscopy, electi'ochemical quartz ciystal microbalance and SEM methods. Potentiodynamic polarisation measurements indicate that studied Schijf base was acting as cathodic type inhibitor. All electi'ochemical measurements show that inhibition efficiencies increase with increase in inhibitor concenlration. This reveals that inhibitive action of inhibitor was mainly due to adsorption on mild steel surfaces. It was found that adsorption of these inhibitors follows Temkin adsorption isotherm. The results of SEM and EQCM measurements indicate that Schiffbase is adsorbed on metal surface and metal is protected against corrosion.

Özet

Potansiyodinamik polarizasyon, lineer polarizasyon, elektroldmyasal empedans speldroskopisi, elektrokimyasal kııartz h'istal mikroterazi ve SEM yöntemleriyle, 0. İM HCl ortamında yumuşak çeliğin korozyomına bir salisilaldimin Schijf bazı olan î,4-Bis[2-(2-hidroltsibenzilidenamino)fenoksi]bUtan 'in inhibitor etkisi araştırılmıştır. Potansiyodinamik polarizasyon ölçümleri Schijf bazının yumuşak çelik için inhibitor özelliğine sahip olduğunu ve bileşiğin katodik inhibitor davranışı sergilediğim göstermiştir. Yapılan tüm ölçümler sonucunda inhibitor etkinliğinin, artan inhibitor derişimi ile arttığı bulunmuştur, inhibitor etkinliğinin derişimle artmasının molelailüıı metal yüzeyine adsorpsiyonıından kaymaklandığı ve molekülün metal yüzeyine adsorpsiyon sürecinin Temkin adsorpsiyon izotermine uyduğu saptanmıştır. Elektroldmyasal kuartz kristal mikroterazi ve SEM sonuçları Schijf bazının metal yüzeyine adsorplandığını ve metali korozyona karşı koruduğunu gösterme foedir.
