Comprehensive study on graphene-based reinforcements in Al2O3–ZrO2 and Al2O3–Ti(C,N) systems and their effect on mechanical and tribological properties

The effect of graphene-based materials: multilayer graphene (MLG), graphene oxide (GO), and nickel-coated graphene (Gn-Ni-P) addition on the mechanical properties of commercial Al2O3–ZrO2 and Al2O3–Ti(C,N) materials is discussed in this paper. The influence of used reinforcements on relative density, microstructure, hardness, and fracture toughness was investigated. Moreover, the combination of strengthening effects deriving from the addition of graphene-based materials and the presence of zirconia or carbon nitride titanium particles was analysed. In order to determine the wear resistance of the obtained composites, tribology test was conducted.
