Lighter and more powerful next generation vehicles and other rotary machinery demand bearings to operate in harsher conditions for higher efficiency, and the continuous development of advanced low-wear and friction materials is thus becoming even more important to meet these requirements. New aluminium composites reinforced with high performance lubricate phases such as graphene nanoplatelets (GNPs) are very promising and have been vigorously investigated. By maintaining a low coefficient of friction (COF) and offering great strength against wear due to their self-lubricating capability, the solid lubricant like GNPs protect the bearing surface from wear damage and prevent change in metallurgical properties during temperature fluctuations. This paper first studies the high-temperature tribological performance of aluminium matrix composites reinforced with GNP, consolidated via powder metallurgy, then elucidates their tribological mechanism. We report that the best tribological performance is achieved by the composite containing 2.0 wt% GNP, with an extraordinarily low COF of 0.09 and a specific wear rate of 3.5×10−2 mm3·N−1·m−1, which represent 75% and 40% reduction respectively, against the plain aluminium consolidated under identical conditions. The in-track and out-of-track Raman analysis have confirmed the role of GNPs in creating a tribofilm on the counterpart surface which contributed to the excellent performance.

“…Due to the need for materials with more diverse in application, metal matrix composites have come to light as promising substitutes for standard alloys in high-strength and stiffness application, e.g. the manufacturing of high strength steel [10,11]. Rice husk ash, clay, groundnut husk, palm kernel shell, sugar cane bagasse, fly-ash, fibres, and whiskers are some of the agricultural by-products found as a suitable material for metal matrix composite (MMC) reinforcements.…”

“…They are still popular and widely used. They are most often produced by stir-casting, and their reinforcement is made of, eg, silicon carbide, boron carbide, or fl y ash [3]. Due to the peculiar properties of aircraft composite materials, the latter are classifi ed as poorly machinable.…”
