Abstract

Bu çalışmada, Al / Y₂O₃ metal matrisli
nanokompozitleri ( %2 ve %4 ağ.) toz metalurjisi ile üretilmiştir. Üretilen
numunelerin mikroyapı ve yoğunlukları incelenmiştir. Mikroyapı karakterizasyonu
partiküllerin homojen dağıldığını göstermiştir. Ayrıca, numunelerin korozyon
davranışları, 20ºC ve 50ºC’de 1 M HCl çözeltisinde potansiyodinamik ve daldırma
testleriyle sistematik olarak incelenmiştir. Korozyon mekanizmalarını anlamak
için, SEM çalışması gerçekleştirilmiştir. Potansiyodinamik korozyon test
sonuçları,  Al / 4Y₂O₃ kompozitinin
oda sıcaklığında en iyi korozyon performansına sahip olduğunu göstermiştir. Daldırma
testi sonunda, yüksek sıcaklıkta (50 ºC), kompozitlerin ağırlık kayıplarının saf Al’a
göre fazla olduğu gözlenmiştir. Oyuklanma ve tane sınırı korozyonu
gözlenmiştir.
