Abstract

In this study, boronizing processes with different parameters were applied to the cementation steels with a diameter of 11 mm. Microstructures were examined using optical and scanning electron microscopes (SEM). Wear and hardness tests were applied both to the untreated sample and to all boronized samples. As a result of boriding processes, a four-fold increase in hardness was observed in the sample boronized at 1000 °C and 16 hours compared to the sample without heat treatment. Although improvements were achieved in hardness and wear performance in the sample boronized at 900 °C and 8 hours, it was observed that the coating thickness was lower than the other samples.

Borlama prosesinin 16MnCr5 çeliklerinin aşınma performansına etkisi

Abstract

Bu çalışmada, 11 mm çapa sahip sementasyon çeliklerine farklı parametrelerde borlama işlemleri yapılmıştır. Optik mikroskop ve taramalı elektron mikroskopu (SEM) kullanılarak mikroyapılar incelenmiştir. Aşınma ve sertlik testleri hem ısıl işlemsiz numuneye hem de borlanmış numunelerin hepsine uygulanmıştır. Borlama işlemleri neticesinde 1000 °C ve 16 saat borlanmış numunede ısıl işlemsiz numuneye göre dört kat sertlik artışı gözlemlenmiştir. 900 °C ve 8 saat süreyle borlanmış numunede sertlik ve aşınma performansında gelişmeler sağlansa da kaplama kalınlığının diğer numunelere göre daha düşük olduğu gözlemlenmiştir.
