“…The TEM images (figures 6(a) and (b)) clearly showed that the interfacial structure of graphene/rGO with Cu exhibited a seamless interface [74]. More specifically, cubic structured Cu and Cu 2 O were clearly identified from the fast Fourier transformation (FFT) image of the selected area (inset image in figure 6 Nautiyal et al reported the fabrication of Cu/Fe-Al 2 O 3 -MoS 2 nano-hybrid composites using spark plasma sintering [76]. Compared with the traditional hot-press sintering process, the slow heating process could result in contamination of the as-prepared powders as well as poor interfacial bonding between the reinforcement materials and MMCs.…”

“…h-BN, as a new type of 2D material, can be used as a 'green' alternative lubricant and offer similar tribological properties. To date, many studies have been incorporating graphene, MoS 2 , WS 2 and h-BN as a composite solid lubricant to achieve better tribological performance [76,[116][117][118][119][120].…”

2D materials including graphene, transition metal dichalcogenide and hexagonal boron nitride (h-BN) have been widely incorporated with metal matrix to form 2D composites. These composites could be widely applied in the field of automotive, aerospace and marine technologies. Due to the strong covalent bonding and unique laminated structure of 2D materials, they can be used as structural reinforcement in metal matrix for enhanced mechanical and tribological properties. In this review, we first introduced various fabrication techniques for achieving high-reinforcement materials (graphene, MoS 2 , WS 2 and h-BN) loading ratio and uniform distribution in the composites. Despite the availability of some conventional methods, we have also discussed novel approaches such as wet chemistry, hot extrusion and compression shearing for reducing contamination and minimizing energy consumption during the fabrication process. Examples of graphene-reinforced Al and Mg matrix composites are discussed where the graphene could effectively increase the tensile strength, compressive strength and hardness of the composites. We have also discussed the use of MoS 2 , WS 2 and h-BN as self-lubrication additives in Al and Cu matrix to reduce the friction coefficient and wear rate.

Cu-(TiC/Al2O3) nanocomposite was synthesized successfully using the powder metallurgy route. The constituents are first ball-milled and then sintered using the spark plasma sintering technique. The tribological and physical properties are investigated. The homogeneity and of ceramics distribution were also evaluated using SEM and XRD. Results showed that TiC and Al2O3 nanoparticles were homogeneously distributed all over the Cu matrix. Copper reinforced with 3 wt.% Al2O3 and hybrid (3 wt.% TiC and Al2O3) had the lowest relative density (95%). The hybrid (3wt. % TiC and Al2O3) sample had a higher wear rate value (1.7*10 -3 ) at 25 N load, while the sample reinforced with 3 wt.% TiC had the lowest value (0.5*10 -3 ) at 25 N load. Cu-Al2O3 exhibited a higher hardness value (149 HV). The highest electrical and thermal conductivities are recorded for the Cu-TiC that were (20.76 MS/m) and (149.03 W/m. k) respectively

“…Ayman Elsayed et al [11] studied experimental investigations for the synthesis of W-Cu nanocomposite through spark plasma sintering, and they concluded that using the SPS technique led to reaching a maximum of 90% relative density. On the other hand, a relative density of 98.1% was reached for Cu-Fe-Al 2 O 3 -MoS 2 composite sintered using the SPS route [33]. Moreover, Babapoor et al [44] investigated the effects of spark plasma sintering temperature on the densification of TiC.…”

Bi-modal particles are used as reinforcements for Cu-matrix. Nano TiC and/or Al2O3 were mechanically mixed with Cu particles for 24 h. The Cu-TiC/Al2O3 composites were successfully produced using spark plasma sintering (SPS). To investigate the effect of TiC and Al2O3 nanoparticles on the microstructure and mechanical properties of Cu-TiC/Al2O3 nanocomposites, they were added, whether individually or combined, to the copper (Cu) matrix at 3, 6, and 9 wt.%. The results showed that titanium carbide was homogeneously distributed in the copper matrix, whereas alumina nanoparticles showed some agglomeration at Cu grain boundaries. The crystallite size exhibited a clear reduction as a reaction to the increase of the reinforcement ratio. Furthermore, increasing the TiC and Al2O3 nanoparticle content in the Cu-TiC/Al2O3 composites reduced the relative density from 95% for Cu-1.5 wt.% TiC and 1.5 wt.% Al2O3 to 89% for Cu-4.5 wt.% TiC and 4.5 wt.% Al2O3. Cu-9 wt.% TiC achieved a maximum compressive strength of 851.99 N/mm2. Hardness values increased with increasing ceramic content.
