MICROSTRUCTURE AND HARDNESS INVESTIGATION OF Fe MATRIX CARBIDE LAYERS ALLOYED BY TIG WELDING METHOD

Abstract

In this study, Cr3C2 powder mixtures added to Fe powder at different rates (5 and 10%) were alloyed to the surface of Ç1020 steel material by TIG (Tungsten Inert Gas) method. Three different current (110, 120 and 130 Ampere) intensities were used in the alloying to be carried out by the TIG method. After surface alloying, sections were taken from the alloy layer, and hardness and microstructure characterization were made. Optical microscopy and SEM+EDS analyzes were used while examining the microstructures. A dendritic microstructure was formed in the alloy layers. In XRD analysis, it was determined that Cr3C2 and Cr7C3 compounds were formed. As a result of the hardness tests taken from the alloyed sample surfaces, it was determined that the hardness value increased throughout the samples with the increase of the current intensity. In addition, the hardness increased with the increase in the addition rate of Cr3C2 powder. In the surface alloyed samples, the highest microhardness value was measured as 485 HV in the sample with 10% Cr3C2 added at 130 A current intensity.

Öz

Bu çalışmada, Fe tozu içerisine farklı oranlarda (% 5 ve 10) ilave edilen Cr3C2 toz karışımları, TIG (Tungsten Inert Gaz) yöntemiyle Ç1020 çelik malzeme yüzeyine alaşımlandırılmıştır. TIG yöntemiyle gerçekleştirilecek olan alaşımlamada üç farklı akım (110, 120 ve 130 Amper) şiddeti kullanılmıştır. Yüzey alaşımlama sonrası alaşım tabakasından kesitler alınarak sertlik ve mikro yapı karakterizasyonu yapılmıştır. Mikro yapılar incelenirken optik mikroskob, SEM+EDS analizleri kullanıldı. Sonuç olarak alaşım tabakalarında dendritik bir mikroyapı oluşmuştur. XRD analizinde Cr3C2 ve Cr7C3 bileşiklerinin oluştuğu tespit edilmiştir. Alaşımlanmış numune yüzeylerinden alınmış mikrosertlik testleri sonucunda akım şiddetinin artmasıyla numunelerin genelinde sertlik değerinde artış olduğu tespit edilmiştir. Ayrıca ilave edilen Cr3C2 tozunun, ilave oranının artmasıyla da sertlik artmıştır. Yüzeyi alaşımlanmış numunelerde en yüksek mikrosertlik değeri 130 A akım şiddetinde %10 Cr3C2 ilave edilen numunede 485 HV olarak ölçülmüştür.
