Abstract
In this study, Stellite 6 was coated onto low carbon steel AISI 1015 through Plasma Transfer Arc (PTA) welding method, and SEM, EDS and XRD analyses of the coated surface were investigated along with some mechanical properties. Measurement of hardness and wear tests have been applied to investigate the mechanical properties. Abrasion experiments were conducted by a Pin-on-Disk wear test device with different levels of abrasive wear. As a result, PTA welding method of low carbon steel AISI 1015 on coatings made of Stellite 6, it was found that surface hardness is improved depending on carbide formation and the amount of the carbide formed, also wear resistance is increased with increasing hardness.
Özet
Bu çalışmada düşük karbonlu AISI 1015 çeliği üzerine, Plazma Transfer Ark (PTA) kaynak yöntemiyle, Stellite 6 kaplanarak, kaplanan yüzeyin SEM, EDS, XRD analizleri ve bazı mekanik özellikleri incelenmiştir. Mekanik özellikleri incelemek adına mikrosertlik ölçümü ve aşınma deneyleri uygulanmıştır. Aşınma deneyleri Pin-onDisk deney cihazında, farklı yüklerde abrasiv aşınma olarak yapılmıştır. Sonuç olarak, PTA kaynak yöntemi kullanılarak, düşük karbonlu çelik AISI 1015 üzerine yapılan Stellite 6 kaplamalarda, karbür oluşumuna ve oluşan karbür miktarına bağlı olarak kaplanan yüzey sertliğinin arttığı, aynı zamanda artan sertlik ile birlikte aşınma direncinin de arttığı tespit edilmiştir.
