Specifications
with different volume fraction were studied using scanning electron microscopy, X-ray diffraction,
and wear testing. The V8C7 particles were uniformly distributed in the matrix, and the size of the
V8C7 reinforcement was 2-12μm. The relative wear resistance of the composites initially
increases decreases with higher V8C7 volume fractions. The best wear resistance of the
composites was 21.2 times higher than that of gray cast iron under a 20N load. This was achieved
at 24% V8C7 volume fraction. Wear of the composites manifests as grooves, broken carbide
particles, and re-embedment of wear debris. © 2013 Elsevier Ltd.
