Abstract

Bu çalışma da 1.0411 çeliğine sementasyon ve nitrasyon işlemleri uygulanarak iç yapı, sertlik ve aşınma davranışları incelenmiştir. Sementasyon işlemi propan gazı, nitrasyon işlemi ise saf NH3 gazı kullanılarak 520 °C’ da gerçekleştirilmiştir. Sementasyon sonrasında numunelere 850 °C sıcaklıkta 25 dakika östenitleştirme, akabinde 60 °C sıcaklıkta su verme işlemleri uygulanmıştır. 140 °C sıcaklıkta 25 dakika menevişleme yapılarak işlem basamakları tamamlanmıştır. Yapılan sertlik öçümleri neticesinde yüzey sertliğinin sementasyon işlemi neticesinde 841±15 HV0.3, nitrasyon neticesinde ise 429±28 HV0.3 ulaştığı tespit edilmiştir. Aşınma yüzeylerine ait SEM görüntüleri alınarak aşınma mekanizmaları belirlenmiştir. Sementasyon işleminin aşınma direncini 2 kat, nitrasyon işleminin ise 2.5 kat artırdığı tespit edilmiştir.

Investigation of the Mechanical and Wear Behavior of 1.0411 Steel Subjected to Gas Carburizing and Nitriding Processes

Abstract

In this study, the microstructure, hardness, and wear behavior of 1.0411 steel were investigated after undergoing carburizing and nitriding processes. The carburizing process was performed using propane gas, while the nitriding process was carried out using pure NH3 gas at 520 °C. After carburizing, the samples were subjected to austenitizing at 850 °C for 25 minutes, followed by quenching in water at 60 °C. The process steps were completed by tempering at 140 °C for 25 minutes. Hardness measurements revealed that the surface hardness reached 841±15 HV0.3 after carburizing and 429±28 HV0.3 after nitriding. SEM images of the wear surfaces were taken to determine the wear mechanisms. It was found that the carburizing process increased wear resistance by 2 times, while the nitriding process increased it by 2.5 times.
