Bakır ve Grafit İçeren Demir Esaslı Malzemelerin İndüksiyon ile Sinterlenmesinde Sinterleme Sıcaklığının Malzeme Dayanımına Etkisi

Abstract

Toz Metal parçaların üretiminin en önemli işlem basamaklarından biri sinterlemedir. Sinterleme aynı zamanda önemli derecede enerji ve zaman tüketiminin olduğu bir ısıl işlemdir. Bu çalışmada ana amaç, aynı dayanım değerleri hedeflenerek, indüksiyon ile sinterleme işlemi vasıtası ile sinterleme sıcaklığının düşürülmesidir. Çalışmada, toz metal numunelerin üretiminde, % 3 Cu, % 0,5 Grafit içeren demir tozu kullanılmıştır. İndüksiyon ile sinterlemenin etkilerinin anlaşılması amacı ile numuneler geleneksel olarak sinterlenerek, üretilen numunelerin mekanik özellikleri ve mikro yapıları karşılaştırılmıştır. Yapılan çalışmalar sonucunda, daha az sürede daha düşük sıcaklıklarda geleneksel sinterlemeye göre daha iyi mekanik özellik değerleri elde edilmiştir.
