Abstract

In this study, the silicon carbide (SiC) powder has been coated by using of GTA process on the surface of a substrate material from 45Mn5 steel. The abrasive wear behaviours of samples which had different amounts of coating powders were determined by pin-on-disc test apparatus. The effects of the formed microstructures and the production parameters on abrasive wear properties of samples in coated zone were investigated. The highest wear resistance was observed at 41.3 kJ/cm energy input, 0.44 mmsn-1 production speed and 2.5 gr. powder quantity. Additionally, the highest micro hardness rate was measured as 1250 HV0.2. It has been observed that through the forming of hard metallographic phases; such as M7C3, M2C and FeSi2 phases, the hardness and the wear resistance of coated surfaces were increased.

Özet

Bu çalışmada, GTA yöntemi kullanılarak alt tabaka malzemesi olarak seçilen 45Mn5 çeliğinin yüzeyine silisyum karbür (SiC) tozu kaplanmıştır. Farklı kaplama tozu miktarları kullanılarak yapılan kaplama işleminde numunelerin abrasiv aşınma özellikleri pim-disk test yöntemi ile belirlenmiştir. Kaplama bölgesinde oluşan mikroyapıların ve üretim parametrelerinin abrasiv aşınma üzerine etkileri araştırılmıştır. En iyi aşınma direnci 41.3 kJ/cm enerji girdisinde, 0.44 mmsn-1 üretim hızında ve 2.5 gr SiC ilavesinde elde edilmiştir. Ayrıca en yüksek mikro sertlik değeri 1250 HV0.2 olarak ölçülmüştür. Mikroyapıda oluşan M7C3, M2C ve FeSi2 fazlarının varlığında parçaların aşınma direncinde ve sertlik değerlerinde yükselme olduğu tespit edilmiştir.
