Küresel grafitli dökme demir numuneleri, kutu (katı) borlama yöntemi ile farklı sıcaklık ve sürelerde borlanmış, daha sonra fırında soğutulmuştur. Isıl işlemlerin darbe dayanımına etkisini kıyaslamak için, küresel grafitli dökme demir numunelere fırında soğutma, suda ve yağda su verme ve temperleme işlemleri gibi farklı ısıl işlemler uygulanmıştır. Uygulanan ısıl işlemler ve borlama parametreleri sonucunda malzemenin darbe dayanımının değiştiği belirlenmiştir. Borlama işlemi ile küresel grafitli dökme demir malzemenin yüzey özellikleri geliştirilmesine rağmen, darbe dayanımında meydana gelmesi muhtemel düşme, servis koşullarında kritik öneme sahip bulunmaktadır. Su verme ve temperleme işlemi ile kıyaslandığı zaman, optimum borlama parametreleri kullanılarak, uygun darbe dayanımının elde edilebileceği sonucuna varılmıştır.

The spheroidal graphite cast iron samples were boronized by the box (solid) boronizing process at different temperatures and times, and then materials were cooled in the furnace. Heat treatments such as cooling in furnace, quenching in water or oil, and tempering treatment were applied to ductile iron specimens in order to compare the effects of different processes on the impact resistance. It has been determined that the impact strength of the material changes as a result of the applied heat treatments and boriding parameters. Although the surface properties of spheroidal graphite cast iron material are improved by the boriding process, the possible decrease in impact strength is critical inservice conditions. It has been concluded that, appropriate impact strength can be obtained by using optimum boriding parameters when compared with the quenching and tempering process.
