Fracture toughness and toughening mechanisms in graphene platelet reinforced Si3N4 composites
TL;DR: In this paper, the authors used various graphene platelets with the aim of improving the fracture toughness of Si3N4 composites, with the highest value of 9.92 MPa/m 0.5.
Journal ArticleDOI
Tribological properties of Si3N4–graphene nanocomposites
TL;DR: In this paper, the properties of nanocomposites with silicon nitride matrix with addition of 1 and 3 ¼ wt% of various types of graphene platelets were studied.
Journal ArticleDOI
Orientation-dependent hardness and nanoindentation-induced deformation mechanisms of WC crystals
TL;DR: In this article, the orientation dependence of hardness and nanoindentation-induced deformation mechanisms of differently orientated tungsten carbide (WC) grains in WC-Co hardmetal were studied.
Journal ArticleDOI
Wear resistance of Al2O3–CNT ceramic nanocomposites at room and high temperatures
