The structure and mechanical properties of composites consisting of a metal matrix based on aluminum and its alloys of different compositions (AA-3003 and AA-5154) and graphene synthes sized in situ under a layer of molten salts were investigated depending on the chemical composition and grain size of the matrix. Aluminum matrix composites of three compositions were studied in as-cast coarse-grained, deformed fine-grained (grain size < 1 mm), and deformed sub microcrystalline (grain size < 1 μm) states in order to compare the structural characteristics of composites with different grain sizes. The composites were subjected to deformation with a split Hopkinson (Kolsky) bar and to dynamic-channel angular pressing. The hardness and dynamic mechanical properties of the composites were measured at strain rates ε˙ from 1.8 − 4.7 × 103 to 1.6 − 2.4 × 105 s−1. It was found that grain refinement induced a sharp increase in the hardness of composites with various compositions (by a factor of 1.6–2.6). A correlation of the elastic-plastic properties of the aluminum matrix composites with the grain sizes and chemical compositions of the matrices was established. A transition from coarse-grained to sub microcrystalline structure was shown to improve the elastic-plastic properties on average by a factor of 1.5. It was proved that the reinforcing effect of graphene increased with the decreasing grain size of the matrix. Mechanisms of reinforcement of the aluminum matrix composites using graphene were proposed.

“…1,2 Graphene (Gr), along with Gr derivatives like Gr oxide (GO), reduced GO (rGO), Gr nanosheets (GNSs), and Gr nanoplates (GNPs) are relatively novel solutions for use as reinforcement agents in metal matrix composites (MMCs) like CuMCs and W-Cu MCs to enhance the microstructure homogeneity, together with an increase in mechanical, electrical, thermal, electrochemical, and functional properties. [26][27][28][29][30][31][32][33][34][35][36] Graphene is a carbon allotrope that comprises a monolayer of sp 2 -hybridized C atoms placed in a 2D hexagonal lattice with one atom thickness of around 0.35 nm. 37 Graphene is commonly synthesized by mechanical cleaving (exfoliation), chemical synthesis by reduction of graphite oxide, thermal CVD, and plasma enhanced CVD methods.…”

This review summarizes the advancement on sintered composites based on tungsten–copper (W–Cu) reinforced with graphene (Gr) or its derivative such as reduced Gr oxide (rGO) for use as electrical contacts applied in switching devices. Main synthesis approaches for preparing Gr or rGO reinforced W–Cu composite powders and their consolidations by using various powder metallurgy techniques are presented. The nature of the initial materials, synthesis conditions, processing parameters, and the relevant findings are disclosed and discussed. The improvement in microstructure and technical characteristics like density, electrical conductivity, hardness, coefficient of friction, wear rate, and arc ablation behavior of W–Cu–Gr/rGO composites are highlighted comparatively with that of unreinforced composites. This review reveals an insight into a novel class of composites as candidates for electrical contact applications.

“…The increased understanding of graphene-based nanofiller and its homogenous dispersion in metal matrix coatings using the electrodeposition process opened up a wide variety of possible applications in fields ranging from medicine to energy. The regulated synthesis of these coatings, with well-defined nanomaterial size, shape, and crystallinity, provided ideal templates for the creation of hydrophobic surfaces, resulting in improved anti-corrosion capabilities [35][36][37][38][39][40][41][42][43][44][45].…”

Graphene derivatives reinforced metal matrix nanocomposite coatings: A review

Due to the extraordinary mechanical, thermal, and electrical properties of graphene, graphene oxide (GO), and reduced graphene oxide (rGO), these materials have the potential to become ideal nanofillers in the electrodeposited nanocomposite coatings. This article provides an overview of literature on the improvements of properties associated with graphene, GO, and rGO-reinforced coatings, along with the processing parameters and mechanisms that would lead to these improvements in electrodeposited metal matrix nanocomposite coatings, where those affected the microstructural, mechanical, tribological, and anti-corrosion characteristics of coatings. The challenges associated with the electroplating of nanocomposite coatings are addressed. The results of this survey indicated that adding graphene into the plating bath led to a finer crystalline size in the composite coating due to increasing the potential development of specific crystalline planes and the number of heterogeneous nucleation sites. This consequently caused an improvement in hardness and in tribological properties of the electrodeposited coating. In graphene reinforced metallic composites, the severe adhesive wear mechanism for pure metallic coatings was replaced by abrasive wear and slight adhesive wear, where the formation of a tribolayer at the contact surface increased the wear resistance and decreased friction coefficient. Furthermore, superhydrophobicity and smaller grain size resulted from embedding graphene in the coating. It also provided a smaller cathode/anode surface ratio against localized corrosion, which has been found to be the main anti-corrosion mechanism for graphene/metal coating. Lastly, the study offers a discussion of the areas of research that need further attention to make these high-performance nanocomposite coatings more suitable for industrial applications.
