Bu çalışmada, fosfat (disodyum fosfat, SP) ve silikat (disodyum silikat, SS) iyonları ile ön işlem yapılmış saf çinkonun klorür
ortamındaki korozyonuna anilin ve Ce³⁺’ün etkisi araştırılmıştır.
Fosfat ve silikat kaplanmış çinko, Ce³⁺ ile etkileştirilip ve
oksalat+anilin çözeltisinde dönüşümlü voltametri alındıktan sonra sodyum klorür
ortamındaki korozyonu potansiyelin zamanla değişimi (OCP), AC-empedans (EIS) ve
akım-potansiyel eğrileri alınarak incelenmiştir. Silikat üzerine yüksek
derişimli seryum kaplama çinkonun korozyon hızının daha düşük
olduğunu ve çinko metalini korozyondan daha fazla koruduğunu (%99) göstermiştir.
