Effect of Heat Treatment and Pulse Plasma Process on Surface Properties of Steels

Abstract

The aim of this study was to examine the effect of heat treatment and pulse plasma treatment on surface properties of AISI 1050 steel used in this work. Firstly, the heat treatment was applied to samples for 2 h at 860 degrees C. The quenching media were selected as water and oil and air cooling was applied. The tempering process was applied at different temperatures like 600 degrees C, 500 degrees C, 400 degrees C and 100 degrees C. Having completed the heat treatment, the pulse plasma process was applied to all samples. The surfaces were investigated with optic microscope, scanning electron microscopy, and X-ray diffraction analyses. The hardness testing was done for all samples from surface to center. The mechanical properties were improved after pulse plasma treatment.
