Östemperlenmiş Küresel Grafitli Dökme Demirlerde İndüksiyonla Yüzey Sertleştirmenin Yorulma Sınırı Üzerine Etkisi

Öz

Bu çalışmada, östemperlenmiş küresel grafitli dökme demirlerde indüksiyonla yüzey sertleştirmenin yorulma sınırı üzerine etkisi araştırılmıştır. Bu amaçla, GGG70 sınıfı küresel grafitli dökme demir numuneler; 900°C’de 90 dk östenitlenmiş ve ardından 375°C sıcaklıktaki tuz banyosunda 120 dk östemperlenmiştir. Daha sonra dökülmüş ve östemperlenmiş koşullardaki yorulma numunelerine yüksek frekanslı indüksiyonla yüzey sertleştirme uygulanmıştır. Dökülmüş halde, östemperlenmiş, dökülmüş halde + indüksiyonla sertleştirilmiş ve östemperlenmiş+indüksiyon ile sertleştirilmiş numunelerin yorulma sınırları, dönel eğmeli yorulma testi cihazı belirlenmiştir. Deneysel sonuçlar, test edilen numuneler arasında en iyi yorulma sınırı sonuçlarını östemperlenmiş+yüzeyi indüksiyonla sertleştirilmiş numunelerin sergilediğini göstermiştir.
