The hardness values are plotted against the distance from surface to core is shown in Fig.6. It exhibits that the surface hardness of the sample is increased by the gas carburizing process. The maximum hardness value on the surface is 423Hv0.05 and the hardness values notably decreased from surface to the core. Fig.6 Micro hardness result analysis The XRD pattern of the gas carburized sample is aided to identify the presence of phases on the surface shown in Fig.7. It confirms that the primary carbides of iron carbide and iron manganese compounds are formed on the surface during the gas carburizing at higher temperatures. Iron carbide is one of the hardest substances which increase the wear resistance of the surface. Fig. 7 XRD result analysis between Gas carburized samples and untreated
