Abstract The wear of aluminum alloy may be decreased by its reinforcement with quasicrystals prepared by melt, which in itself has good wear-resisting properties. This research paper considers the part played by a dense Al-Fe-Cr quasicrystal (QC) reinforced Al matrix composite fabricated by the directed energy deposition (DED) in reducing wear between sliding surfaces and discusses briefly some of the factors which, in practice, explain ceramic-like properties of quasicrystal including low friction and wear resistance. The hardness of reinforcement phases, QC Al91Fe4Cr5 and Al13(Fe, Cr)4, was up to ~ 91 and ~ 112 HV respectively, while the Al matrix was just ~ 70 HV. Furthermore, the reinforcement phases contributed to form the mechanical mixing layer (MML) which significantly decreased the coefficient of friction (COF) and improves the wear resistance. With the increase of load from 1N to 5N, the COF dropped from 0.82 to 0.33 because the higher load was beneficial to the formation of harder and denser MML. Through the comprehensive analysis of the wear test and worn surface, the wear behavior and mechanism of this QC reinforced Al matrix composite has been explained in detail. The results indicate that the quasicrystal reinforced Al matrix composites formed by DED is one of the promising wear-resistance materials.

SiC particulates reinforced metal matrix composites (MMCs) were fabricated by two different processes, pressureless infiltration and thermal spray. 10, 20, 30, 40 and 50 vol% SiC reinforced Al matrix composites (AMCs) were fabricated by these two processes. For these AMCs, dry sliding wear tests were performed under a normal load of 3 N, a constant sliding speed of 0.2 m/s and sliding distance of 1000 m against an AISI 52100 ball. Microstructures and wear behavior were studied by means of scanning electron microscope (SEM) and electron probe micro-analysis (EPMA).

Multilayer reduced graphene oxide (mrGO) was chemically modified by electroless plating of copper on surface to form mrGO-Cu. The scanning electron microscope (SEM) and transmission electron microscope (TEM) analysis revealed that nano-Cu particles were uniformly dispersed on the surface of mrGO. The mrGO-Cu powders were further utilized as reinforcements for aluminum (Al) matrix and the mrGO-Cu/Al composite was successfully fabricated through clad rolling of milled powder. The tribological properties of the mrGO-Cu/Al composites were explored. The tribological results show that the mrGO-Cu could reduce the friction coefficient and wear loss of mrGO-Cu/Al composites, since the mrGO-Cu participated in lubricating processes due to the formation of a transfer layer on the contact surface. Furthermore, it is found that the composition of mrGO-Cu could significantly influence the tribological properties of the mrGO-Cu/Al composites. The composites with 4% of mrGO-Cu for composites exhibited the best tribological behavior, which transformed from adhesive wear to abrasive wear, due to the formation of a graphite lubricating film.

In this paper, the applicability of aluminium matrix composites to high-temperature working conditions (not exceeding the Al melting point) was evaluated. The behaviour of Al-Ti-C composites at elevated temperatures was described based on microstructural and phase composition observations for composites heated at temperatures of 540 and 600 °C over differing time intervals from 2 to 72 h. The materials investigated were aluminium matrix composites (AMC) reinforced with a spatial carbon (C) structure covered by a titanium (Ti) layer. This layer protected the carbon surface against contact with the aluminium during processing, protection which was maintained for the material’s lifetime and ensured the required phase compositions of Al4C3 phase limitation and AlTi3 phase creation. It was also proved that heat treatment influenced not only phase compositions but also the microstructure of the material, and, as a consequence, the properties of the composite.
