In this study, hardness values of borided low carbon microalloyed steels were measured. The boronizing treatment was performed at 1123 K under various exposure times using Ekabor-II commercial powders. The presence of FeB and Fe2B phases in the boride layer of the boronized low carbon microalloyed steels were observed using an X-ray diffractometer and energy dispersive spectroscopy (EDS) analysis. It was concluded that boride layer thickness and hardness values increase with increasing boriding time due to hard boride phases and diffusion as a result of boronizing process
Özet: Bu çalışmada, borlanan düşük karbonlu çeliklerin sertlik değerleri ölçülmüştür. Borlama işlemi 1123 K sıcaklıkta ve değişik sürelerde ticari ekabor-II tozları kullanılarak gerçekleştirilmiştir. Yapılan X Işınları Kırınımı (XRD) ve Enerji Dağınım Spektroskopisi (EDX) analizleri ile borlanan düşük karbonlu mikroalaşımlı çeliklerin borür tabakasında FeB ve Fe2B fazlarının oluştuğunu gözlenmiştir. Borlama işleminin bir neticesi olarak difüzyon ve oluşan sert bor fazlar yüzünden, borlama süresi ile borür tabakası kalınlığı ve sertlik değerlerinde bir artışın olduğu sonucuna varılmıştır.

The Effect of Boriding Time on Hardness Values of Low Carbon Micro Alloyed Steels
Abstract: In this study, hardness values of borided low carbon microalloyed steels were measured. The boronizing treatment was performed at 1123 K under various exposure times using Ekabor-II commercial powders. The presence of FeB and Fe2B phases in the boride layer of the boronized low carbon microalloyed steels were observed using an X-ray diffractometer and energy dispersive spectroscopy (EDS) analysis. It was concluded that boride layer thickness and hardness values increase with increasing boriding time due to hard boride phases and diffusion as a result of boronizing process.
