CoCrMo alloy has been oxidized for 3 and 5h at the temperature of 850°C with 100% O2 gas by thermal oxidation. The XRD, SEM, microhardness and ball-on-disc wear test devices were used to find out the structure, mechanical and wear properties of untreated and treated specimens. Outcomes showed wear resistance of oxidized specimens were became better than untreated CoCrMo alloy. Also, wear resistance of oxidized specimens improved with increased processing time (from 3h to 5h) increased.

Termal Olarak Oksitlenmiş CoCrMo Alaşımının Aşınma Davranışı Üzerine Oksidasyon Süresinin Etkisi

Öz

CoCrMo alaşımı, %100 O2 gazı ortamında, 850°C'de, 3 ve 5 saat süre ile termal oksitlenmiştir. İşlemsiz ve işlem görmüş numunelerin yapısal, mekanik ve aşınma özelliklerin tespit edilmesi için XRD, SEM, mikro sertlik ve pim-disk aşınma test cihazları kullanılmıştır. Sonuçlar, oksitlenmiş numunelerin aşınma dirençlerinin, işlem görmemiş CoCrMo alaşımından daha iyi olduğunu göstermiştir. Ayrıca, oksitlenmiş numunelerin aşınma dirençleri, işlem süresi arttıkça (3 saatten 5 saate kadar) artmıştır.
