Novel aluminum-graphene and aluminum-graphite metallic composite materials: Synthesis and properties

Raman spectroscopy study of graphene formed by “in situ” chemical interaction of an organic precursor with a molten aluminium matrix

“…The aluminium‐graphene materials were obtained by the interaction of molten aluminium with carbon precursor under a molten mixture of alkali and alkaline earth metal halides in a corundum crucible and a vertical heating furnace …”

“…In addition, a corrosion test was carried out, which was described in detail in . Similarly, to the case of the aluminium‐graphene composite formed from a carbide precursor, the aluminium‐graphene composite obtained from their glucose does not interact with water with the release of methane, which also confirms the absence of aluminium carbide in the composite.…”

“…Together with the co‐authors, L. A Yolshina has developed and patented an innovative method for synthesising metal matrix composite materials containing graphene layers uniformly distributed during the chemical interaction of molten metals with inorganic carbon‐containing precursors—non‐metallic carbides—beneath a layer of molten halides of alkali metals without formation of aluminium carbide in them . A distinctive feature of the method for obtaining the described composite materials is the direct formation of “in situ” graphene nanoparticles from carbon‐containing precursors within a metal matrix in a medium of molten salts.…”

Peculiarities of fullerenes and carbon onions application for reinforcing the aluminum matrix in the metal matrix composites

“…Much attention is devoted to the development of new composites, since they can exhibit the properties unattainable in conventional nonreinforced materials . Many investigators have studied aluminum matrix composites with carbon reinforcements and possible reaction between aluminum and carbon . Nanopowder application in composites enables improvement of a number of key properties; however, the temperature range of such composite application must be studied.…”

Enhancement of the mechanical properties of aluminum-graphene composites

“…Even small aluminum carbide additions damage aluminum-graphene composite materials in aggressive environments, and even in atmospheric conditions. This paper is focused on explaining a new method for aluminum-carbon synthesis with high concentration and uniform distribution of graphene sheets free of aluminum carbide [2]. These metallic composites have a composition of carbon up to 2% in weight and no aluminum carbide formation at 1073 K.…”
