Özet

Gas nitriding is a widely applied thermochemical surface treatment, which is applied to enhance mechanical properties and wear characteristics of iron and steels. The impact of the gas nitriding process on the mechanical and wear resistance characteristic of DIN 1.2344 (X40CrMoV5-1) hot work steel were investigated in this paper. Nitrided and non-nitrided samples were characterized through a different method such as the optical microscope, scanning electron microscopy, energy dispersive spectrometry, X-ray diffraction, atomic force microscope (AFM) and 3D optical profilometer. The results of analyses reveal that increases in wear resistance of the nitrided sample due to the formation of surface layers of nitrides and oxides.
