“…In addition to the above-mentioned methods, matrix composites can also be used to improve the i properties of Si 3 N 4 . Components such as TiN, SiC whiskers, ZrO 2 nanofibers and graphene can be used as reinforcing phases [11][12][13][14][15][16]. Very interesting research results have been obtained in the case of composites reinforced with graphene.…”

This paper discusses the influence of Ti3C2 (MXene) addition on silicon nitride and its impact on the microstructure and mechanical properties of the latter. Composites were prepared through powder processing and sintered using the spark plasma sintering (SPS) technic. Relative density, hardness and fracture toughness, were analyzed. The highest fracture toughness at 5.3 MPa·m1/2 and the highest hardness at HV5 2217 were achieved for 0.7 and 2 wt.% Ti3C2, respectively. Moreover, the formation of the Si2N2O phase was observed as a result of both the MXene addition and the preservation of the α-Si3N4→β-Si3N4 phase transformation during the sintering process.

“…The intrinsic mechanical properties of graphene make it one of the strongest materials available [9][10][11]. Graphene is considered to have excellent electrical properties [12][13][14] and high thermal resistance [15][16][17] as well as a high surface area (highest adsorption and surface reactions), electron mobility, thermal conductivity and mechanical strength [18]. GrO can also be used as nanofiller since it has similar properties to graphene and has become more commonly available recently.…”

The sintering of ceramic matrix composites is usually carried out by raising the sintering temperature below the melting point of components. Spark plasma sintering (SPS) has the capability to densify ceramics at a relatively low temperature in a very short time. Two different additions, multilayered graphene (MLG) and graphene oxide (GrO), were added to Si3N4 ceramic matrix in various amount; 5 wt% and 30 wt%. The influence of reinforcing phase on final properties of spark plasma sintered Si3N4 composite was studied. The uniaxial-pressure-assisted SPS sintering resulted in a preferential alignment of both type of graphene in the Si3N4 ceramic matrix, leading to highly anisotropic properties with lower mechanical behavior but better tribological and electrical properties.

“…Further, different nanoscale carbon forms like carbon nanotubes (CNTs), graphene nanoplatelet (GNPs) addition is also prefered to improve fracture toughness of this material in recent years. Especially, graphene-based materials have more attention for the reinforcement of ceramics, due to their extraordinary thermal, electrical and mechanical properties [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] Graphene is well known two-dimensional (2D) material which is an allotrope of carbon consisting of a single layer of strong in-plane covalent bonds between adjacent carbon atoms. Excellent high fracture strength (125 GPa), high young modulus (1 TPa), superior thermal conductivity (5000 W/mK) properties, it is considered to be a popular candidate material as the second phase of ceramic matrix composites.…”

Graphene nanoplates reinforcement (GNPs) TaB2-SiC composites were fabricated with Spark Plazma sintering (SPS) at 1850°C with a-uniaxial pressure of 50 MPa and 10 min dwell time. Systematic investigation on the effect of GNP amount ofdensification, microstructural and mechanical properties (microhardness and fracture toughness) of the composites were presented. Density and hardness of composites decreased with the addition of GNP, while ~35% increase of fracture toughness value was obtained with GNP addition. The microstructural evaluation indicated that overlapped and agglomerated GNPs increased with an increasing amount of GNP in the composites and caused to decrease of density and hardness. On the other hand, GNP was retained in the composite form even with high process temperature (1850°C) and cause toughening of composites with changing the fracture mode from transgranular to transgranular/intergranular fracture. GNP pull out, crack branching, crack bridging and crack deflection were observed as main toughening mechanisms.
