Abstract

Vanadium carbide (VC) particulate reinforced Fe-based composite was produced using in situ synthesis technique. The effect of sintering temperature on the densification of Fe-VC composite was investigated. The wear resistance of Fe-VC composite was evaluated using pin-on-disk tests. The phases of Fe-VC composite were determined by X-ray diffraction analysis, and the microstructure of Fe-VC composite was characterized by scanning electron microscopy and transmission electron microscopy. The results show that the optimal sintering temperature is 1473 K; Fe-VC composite consists of VC phase and α- Fe phase; fine spherical VC particles distribute uniformly in iron matrix; and the composite possesses great wear-resistance.
