Enhancement Wear Properties of HSS-M2 Tool Steel with WC Deposited by SMAW Process

Abstract

In this study, the effect of cladded tungsten carbide layer upon HSS - M2 tool steel on microstructure, hardness, and wear behavior has been studied in two cases without using the middle layer and using the middle layer of nickel. Tungsten Carbide cladded on <br /> HSS - M2 tool steel by Arc Weld ( SMAW ). The ASTM-G65 wear test was used to determine its application for use in the mineral industry. The results show that the formation of M6C ( tungsten - rich carbide) is deposited layer, as well as tungsten carbide with the formation of a composite layer on the base metal surface, increases the wear resistance up to 60% and the hardness up to 150% compared to the uncoated sample. Comparing the results in terms of the use or non-use of the middle nickel layer indicates the improvement of wear behavior in conditions without using middle nickel layers.
