چکیده انگلیسی
In the case of cemented WC, Ni or Co is added as a binder for the formation of composite structures. However, the high cost of Ni or Co, the low hardness and the low corrosion resistance of the WC-Ni and WC-Co cermets have generated interest in recent years for alternative binder phases. In this study, FeAl3 was used as a novel binder and consolidated by the pulsed current activated sintering (PCAS) method. Highly dense WC-FeAl3 with a relative density of up to 97% was obtained within 2Â min by PCAS under a pressure of 80Â MPa. The average grain sizes of the sintered WC and WC-FeAl3 were lower than 100Â nm. The addition of FeAl3 to WC enhanced the mechanical properties and increase of relative density.
