Fabrication and Microstructures of WC-Based Composites by Plasma Jet Metallurgy

Abstract:

The WC-Fe bulk composites were prepared by means of the plasma jet metallurgy using WO₃, C and Fe-based alloy powder as raw materials. Phases of the composites were mainly WC, W₂C, M₆C, M₇C₃ and (Fe, Ni).The WC grains formed in situ had rectangular or triangular shapes with size of 30-70μm. The growth morphology of Fe₃W₃C was faceted polygon and herringbone. The formation of the unique composite microstructure was attributed to the incomplete peritectic reaction between W₂C and Fe₃W₃C.
