“…Finally, in [46], it was demonstrated that annealing of AA5049 aluminum alloy-based composites reinforced with non-stoichiometric cubic WC-coated CNTs in the temperature range of 500-600 ºC leads to significant structural changes, which were characterized using HRTEM, XRD, and Raman spectroscopy. At an annealing temperature of 500 ºC, diffraction patterns of the composite revealed the appearance of peaks corresponding to the solid solution of tungsten.…”

This brief overview provides a systematic organization of the known thermodynamic data to justify approaches for inhibiting the in-situ formation of Al4C3 reaction between carbon nanotubes and aluminum matrix in composite materials. Based on the literature data, the Gibbs free energy value at a temperature of 600 ºC is calculated for aluminum and carbon interactions with various substances. Approaches for inhibiting the interfacial reaction and the formation of the Al4C3 phase in aluminum matrix composites are proposed by controlling their composition. These approaches involve alloying the matrix with different elements and ex-situ modification of carbon nanotubes through the creation of coatings with varying compositions on their surface prior to their incorporation into the matrix. Literature data on the effect of the interfacial layer on the properties of Al/CNT composites are presented. The promising outlook of the interface design strategy by controlling the type and thickness of the interphase layer for the engineering of composites with improved properties is shown. This approach can be useful in the development of aluminum matrix composite materials with balanced properties for a wide range of applications.

“…Процесс проводили в условиях форвакуума с использованием в качестве прекурсора гексакарбонила вольфрама W(CO) 6 (ГКВ). Гибридный материал был апробирован в качестве армирующего наполнителя в АКМ [12,13]. Было установлено, что после высокотемпературного отжига при температуре выше 525 • C покрытие WC 1−x на поверхности МУНТ вступает в реакцию с алюминиевой матрицей с образованием интерметаллидной фазы WAl 12 .…”

By the method of chemical vapor deposition of tungsten hexacarbonyl at atmospheric pressure in an argon flow has been used to obtain promising fillers for aluminum matrix composite materials in the form of a mixture of nanoparticles of non-stoichiometric cubic tungsten carbide (WC1-x) and hybrid nanomaterials based on multi-walled carbon nanotubes decorated with nonstoichiometric cubic tungsten carbide. The influence of chemical vapor deposition (CVD) parameters on the morphology of samples was studied and the optimal synthesis conditions were selected. The structure and composition of the synthesized materials were studied by electron microscopy and X-ray phase analysis
