Abstract

Carbidic austempered ductile iron, which attracts considerable attention in wear applications recently, due to its superior abrasive wear resistance and sufficient impact toughness, is the latest member of ductile iron family. A new technology and additional investment are not required for the production of these irons. So, the manufacturing process of these irons is easier and cheaper than that of many wear resistant materials. As a result, it is seen that the wear performance of these irons can be comparable with that of high Cr abrasive wear resistant irons, when considering cost efficiency and impact toughness.

Özet

Karbürlü östemperlenmiş küresel grafitli dökme demirler, üstün abrasif aşınma dirençlerinin yanında yeterli darbe tokluğuna da sahip olmaları nedeniyle son zamanlarda aşınma uygulamalarında dikkat çeken küresel grafitli dökme demir ailesinin en yeni üyelerinden biridir. Bu dökme demirlerin üretimi için yeni bir teknolojiye veya ek yatırıma ihtiyaç duyulmadığından pek çok aşınma dirençli malzemeye nazaran imalat süreçleri daha kolay ve ucuzdur. Bu çalışmada karbürlü küresel grafitli dökme demirlerin bileşimleri, üretimleri, ısıl işlemi, işlem sonucundaki içyapısı ve aşınma dayanımları detaylı olarak incelenmiştir. Çalışmanın sonucunda, maliyet ve darbe tokluğu göz önüne alındığında; bu dökme demirlerin aşınma performansının yüksek kromlu abrasif aşınma dirençli dökme demirlerinki ile mukayese edilebilir ölçüde olduğu görülmüştür.
