In this study, Samples of concussor jaws were welded using different types of hard electrodes. These welded parts were subjected to wear test under different loads, and changes in the hardness and microstructures were examined. A pin-on-disc wear test apparatus was used. It is found that wear resistance decreased as the load and the distance were increased. The wear resistance also varied according to hardness.

FARKLI TİP DOLGU ELEKTROTLARI İLE DOLGULARI YAPILAN BOR KIRICI ÇENELERİN AŞINMA DAVRANIŞLARININ İNCELENMESİ

Öz

Bu çalışmada, bor madeninin işlenmesinde kullanılan kırıcı çenelerden alınan numuneler, farklı sert dolgu elektrotları ile dolguları yapılmıştır. Farklı elektrotlarla yapılan dolgu kaynaklarının değişik yükler altındaki aşınma davranışları, sertlik değişimleri ve mikroyapıları incelenmiştir. Aşınma deneylerinde Pin-on-disk aşınma test cihazı kullanılmıştır. Değerlendirmeler sonucunda artan yük ve mesafeye bağlı olarak aşınma miktarının arttığı, aşınma miktarının sertliğe bağlı olarak değiştiği tespit edilmiştir.
