Abrasion and impact Wear Resistance of the Fe-based Hardfacing Weld by Dispersing the Recycled WC

The abrasion and impact wear resistance were investigated on the hard facing weld dispersed with the recycled hard metal(HM). The I-1M was composed of the tungsten carbide(WC) reinforced metal matrix composite. The cored wire tilled with the 35 wt.% HM and 0-6 wt.% of the alloying element, Fe-75Mn-7C(FeMnC), was used for the gas metal arc(GMA) welding. The FeMnC addition to the 35 wt.% HM did not improve the abrasion wear property since the amount of the tungsten carbide fOn11ed was decreased with respect to the FeMnC amount. However, the 6 wt.% FeMnC addition to the 35 wt.% I-1M exhibited the better impact wear resistance than the hard facing weld by the 40 wt.% 11M.
