Klorürlü Çözeltilerde Sülfatiyazolün Alüminyum Korozyonuna Etkisi

Sibel Zor, Elif Yıldız

Öz


Bu çalışmada sülfatiyazolün 0,1 M NaCl çözeltisindeki alüminyum korozyonuna inhibisyon etkisi, farklı sıcaklıklarda potansiyodinamik  polarizasyon eğrileriyle ve SEM analizleriyle incelenmiştir. Polarizasyon eğrilernden sülfatiyazolün karışık inhibisyon etkisi gösterdiği belirlenmiştir. Langmuir adsorpsiyon izotermi kullanılarak adsorpsiyon serbest enerjisi ve adsorpsiyon denge sabiti hesaplanmıştır. Sıcaklık etkisi Arrhenius eşitliği kullanılarak açıklanmıştır.
