WC/Fe composite material and preparation method thereof

The invention discloses a WC/Fe composite material and a preparation method thereof. WC powder, Fe powder, graphite, Cu powder, Mn powder and Ni powder are adopted as raw materials, and the raw materials comprise the following components including, by mass, 20%-50% of the WC powder, 0.1%-1% of graphite powder, 0.5%-1.5% of the Cu powder, 1%-8% of the Mn powder, 5%-10% of the Ni powder and the balance iron powder; and the WC/Fe composite material is prepared through weighing, ball-milling, drying, forming and sintering. According to the WC/Fe composite material, Mn and Ni alloy elements are added into matrix alloy components, and the matrix structure and performance of the composite material are changed by utilizing the solid solution strengthening effect of the alloy elements, so that the overall performance of the composite material is improved. According to the WC/Fe composite material, the Ni element is added to promote formation of tungsten carbide, the form of the composite material is improved, the inte
