Nano/microstructures and mechanical properties of Al2O3-WC-TiC ceramic composites incorporating graphene with different sizes

Graphene additives with different sizes were employed to strengthen and toughen Al2O3-WC-TiC ceramic composites. The effect of graphene sizes on interfacial characteristics, microstructures and mechanical properties was investigated. The results indicated that the interfacial chemistry reaction products and sizes of the products were subject to graphene sizes. With the increase of graphene thickness, the interfacial reaction products between...
