Mechanical properties of nanocomposition ceramics with graphene

This paper presents the results of mechanical tests by nanoindentation method of nanocomposite Al2O3 ceramics with 0.5 wt.% graphene obtained by plasma spark sintering. The following mechanical properties were studied depending on indentation depth: micro- and nanohardness, Young's modulus. Special attention was paid to fracture toughness. It is shown that the addition of carbon in the form of graphene can improve some of the properties of nanocomposite ceramics.
