A Comparative Investigation on the Wear Performance of Compacted Graphite Iron (CGI) Treated with Single and Double Tempering

Öz

Compacted graphite iron (CGI) is a critical material in today's automotive and manufacturing industries. Heat treatment processes can improve CGI wear properties, related primarily to microstructural changes. In this study, single and double tempering heat treatments were used to improve the wear properties of CGI. Oil quenching was performed after 90 minutes of austenitization at 900°C, followed by 60 minutes of single and double tempering at three different temperatures (315, 350, and 375°C). The wear performance of the samples was compared using a pin-on disc test and hardness measurements. The volume loss and friction coefficient were evaluated, and wear maps were constructed to determine the samples' wear behavior. SEM and EDS analyses were carried out to worn surfaces to interpret the relationship between wear mechanism and microstructure. According to the study's findings, double tempering heat treatment may optimize wear performance better than traditional single tempering, and structures with high toughness-wear resistance combinations can be obtained.

Tek ve Çift Temperleme İşlemi Yapılmış Vermiküler Dökme Demirin (VDD) Aşınma Performansı Üzerine Karşılaştırmalı Bir Araştırma

Öz

Vermiküler dökme demir (VDD), günümüzün otomotiv ve imalat endüstrilerinde kritik bir malzemedir. Isıl işlem süreçleri, büyük ölçüde mikroyapısal değişikliklerle ilgili olan VDD aşınma özelliklerini iyileştirebilmektedir. Bu çalışmada, VDD'nin aşınma özelliklerini iyileştirmek için tek ve çift temperleme ısıl işlemleri kullanılmıştır. 900°C'de 90 dakikalık östenitleme ve yağda su vermeden sonra üç farklı sıcaklıkta (315, 350 ve 375°C) 60 dakika süreyle tek ve çift temperleme uygulanmıştır. Numunelerin aşınma performansı, pin-on disk testi ve sertlik ölçümleri kullanılarak karşılaştırılmıştır. Numunelerin aşınma davranışını belirlemek için hacim kaybı ve sürtünme katsayısı incelenmiş, ayrıca aşınma haritaları oluşturulmuştur. Aşınma mekanizmaları ile mikro yapı arasındaki ilişkiyi yorumlamak için aşınma yüzeylerine SEM ve EDS analizleri uygulanmıştır. Çalışmanın bulgularına göre, çift temperleme ısıl işlemiyle aşınma performansının geleneksel tek tavlamaya göre daha iyi optimize edilebileceği ve yüksek tokluk-aşınma direnci kombinasyonuna sahip yapılar elde edilebileceği belirlenmiştir.
