Bu çalışmada, plazma sprey
yöntemi ile AISI 316L üzerinde üretilmiş ZrO2-%8
Y2O3 kaplamaların mikroyapı ve mekanik özellikleri
üzerine ısıl işlemin etkisi araştırılmıştır. Seramik kaplamalar, 900°C, 1000°C
ve 1100°C sıcaklıklarda ısıl işlem prosesine tabi tutulmuştur. Kaplama
tabakalarının faz bileşimi ve mikroyapısı X-ışını difraktogramı (XRD) ve
taramalı elektron mikroskobu (SEM) ile incelenmiştir. Kaplamaların aşınma
özellikleri ASTM G133 test standartları referans alınarak aşınma test cihazında
ball on disk yöntemi ile test edilmiştir. SEM çalışmalarına göre, en fazla
gözenek oluşumu ısıl işlemsiz numunede görülürken, ısıl işlem sıcaklığı
arttıkça gözenek miktarının azaldığı tespit edilmiştir. Fakat ısıl işlemin
arayüzey bağlanmasına olumsuz etki ettiği de kaçınılmaz bir sonuç olarak elde
edilmiştir. Kaplama mikroyapısında t-ZrO2 ve c-ZrO2
fazlarının oluştuğu XRD analizlerinden belirlenmiştir. Sonuçlar, ısıl işlem
sıcaklığının artmasıyla, kaplamaların sertliklerinde artış olduğunu ve sürtünme
katsayılarında ve aşınma oranlarında ise azalma meydana geldiğini göstermiştir.
