<p>The present invention relates to a method for producing a graphene-alumina-zirconia composite having excellent wear resistance, wherein the method comprises the steps of: (a) producing a graphene dispersed liquid in which graphite is peeled; (b) preparing alumina powder and zirconia powder; (c) producing ceramic slurry by mixing the alumina powder and zirconia powder in a polar solvent; (d) adding and mixing the ceramic slurry in the graphene dispersed liquid; (e) drying and molding a mixed byproduct; and (f) sintering a molded product. By means of the present invention, a graphene-alumina-zirconia composite having high wear resistance, fracture toughness, and bending strength can be easily produced.</p> |
