Abstract
The abrasion and impact wear resistance were investigated on the hardfacing weld dispersed with the recycled hard metal(HM). The HM was composed of the tungsten carbide(WC) reinforced metal matrix composite. The cored wire filled with the 35 wt.％ HM and 06 wt.％ of the alloying element, Fe75Mn7C(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 formed was decreased with respect to the FeMnC amount. However, the 6 wt.％ FeMnC addition to the 35 wt.％ HM exhibited the better impact wear resistance than the hardfacing weld by the 40 wt.％ HM.
