Microstructure Development of Low Carbon Steel Surface Hard-Faced by Chromium Carbide Alloy

EasyChair Preprint 13642

Abstract

In this investigation, the microstructure changes of low carbon steel hard-faced by chromium carbide containing alloy was studied using XRD and SEM analysis. Three group of samples were used in the study. First group of samples was pure low carbon steel without any surface treatment. Second and third group of samples were weld coated with different concentration of chromium contents with 3.2 and 3.8 %. XRD and SEM analysis results show that the microstructure of the surface treated samples consist of little ferrite and much of pearlite. XRD test shows the chromium contents of both of ferrite and pearlite have increased significantly. Increasing of pearlite amount and increasing the chromium concentration in every phases affect to increase of hardness from 140 to 410 HB. Chromium content was increased in pearlite an ferrite up to 2.8 and 3.25 respectively. This increasing causes the phases hardness to be increased
