▎ 摘　　要

NOVELTY - Producing alumina-tungsten carbide-graphene nanosheet composite ceramic material, comprises uniformly dispersing alumina, titanium tungsten carbide, magnesium oxide and yttrium oxide in a graphene nanosheet suspension, ball-milling, drying, and sieving to obtain a raw material powder, and sintering the raw material powder at a high temperature and a high pressure, and then cooling. USE - The method is useful for producing alumina- titanium-tungsten carbide-graphene nanosheet multiphase ceramic material (claimed). ADVANTAGE - The method produces ceramic material with improved flexural strength, hardness, fracture toughness and wear resistance, and is simple and convenient.
