Summary: The recent advancement in graphene-reinforced aluminium matrix composites has improved wear behaviour and enhanced the performance of lightweight nanocomposites. The use of graphene nanoparticles as self-lubricants has shown promising results in increasing wear resistance, reducing friction coefficients, improving efficiency, and extending the lifespan of sliding components. However, the challenge lies in achieving a homogeneous distribution of graphene in the aluminium matrix due to its tendency to agglomerate and poor wettability. Proper processing methods and the addition of magnesium can enhance the wettability of graphene and improve the wear and friction properties of the composites.

Summary: This study evaluated the mechanism of material removal with the help of mechanically mixed layer, focusing on aluminium matrix alloy and its composite. The investigation found that the composite had better hardness and wear resistance than the alloy, with a mechanically mixed layer forming under low load but not under high load. The maximum wear resistance was observed for fine abrasive and low load conditions, with a transition in material removal for high abrasive sizes.

Summary: Hybrid nanocomposites of aluminium (NHAMMCs) made from AA5052 are fabricated by adding 12 wt% Si3N4 and 0.5 wt% graphene through stir casting for aeronautical and automotive applications. The wear characteristics of NHAMMCs are evaluated using response surface methodology based on Box-Behnken design. The Orowan strengthening mechanism is observed and it improves the strength of the composite. Higher axial load and rotational speed result in significant increase in wear loss, while increased sliding distance and sliding time have no considerable effect due to the lubricating nature of reinforced graphene particles.

Summary: By incorporating carbon spheres and graphene into epoxy composites, the thermal and wear properties of the composites can be improved, even at low graphene content. Through chemical functionalization of graphene by grafting epoxy chains, the total performance of the composites, especially the wear resistance, was significantly enhanced, with a reduction of wear rate by 95% at 20 wt.% E-g-AM compared to pure cured epoxy resin.

Summary: The study revealed that the superlubricity mechanism of glycerol-lubricated Si3N4 is achieved through the formation of graphene nitride layers, which passivate the ceramic surfaces and induce extremely low friction under boundary lubrication. This suggests a high potential for the use of glycerol-lubricated Si3N4 in green superlubricity enabled by in situ synthesis of disordered graphene nitride species.

Summary: Addition of 0.7 wt% rGO as a reinforcement phase in ADC12 alloy can significantly reduce friction and wear volume, while increasing material hardness. High-resolution TEM imaging shows that rGO wraps around microstructural silicon, inhibiting primary silicon growth and enhancing interfacial strengthening.

Summary: Introduction of nano silicon nitride (Si3N4) into polyvinylidene fluoride (PVDF)-based film improves its dielectric thermal stability and energy storage performance. Increase in the amount of Si3N4 doping enhances the discharging energy density and thermal dielectric relaxor temperature of the composite film, making it more suitable for high-temperature energy storage applications.

Summary: This study reports the processing and characterization of graphene-reinforced aluminium alloy 7075 microcomposites and nanocomposites. The nanocomposites have higher density compared to the microcomposites, and their hardness increases proportionally with the addition of graphene. The wear mechanisms of the composites differ, with microcomposites showing abrasive and ploughing wear, while nanocomposites exhibit adhesive wear with delamination and particle pull-out from the material surface.

Summary: This study focused on establishing the tribological characteristics of Al7068/Si3N4/BN hybrid metal matrix composites prepared by the stir casting route. Wear experiments were conducted to analyze the impact of different weight percentages of Si3N4 and BN particles on wear rate and coefficient of friction. Results showed that the composite material reinforced with 10 wt. % of Si3N4 and 5 wt. % of BN exhibited the minimum wear rate.

Summary: In this study, hexagonal boron nitride nanoparticulates and graphene nanoplatelets reinforced aluminum matrix composites were produced via powder metallurgy process. The mechanical properties, including density, hardness, and compressive strength, were significantly improved in composites with 1%BN and 0.15%graphene content. However, exceeding these contents resulted in decreased mechanical strength due to the aggregation of graphene nanoplatelets and nano-BN particles.

Summary: This study investigated the reinforcement of aluminum-based composites with pure alumina, pure graphene, and their hybrid forms through powder metallurgy. It was found that adding an appropriate amount of graphene can improve the Vickers hardness and ultimate compressive strength of aluminum hybrid composites, but excessive graphene content can lead to a decrease in these mechanical properties due to the clumping of graphene nanoparticles.
