AbstractNew hybrid materials based on multiwalled carbon nanotubes (MWCNTs) with a nonstoichiometric tungsten carbide coating (WC_1 –_ x /MWCNTs) were synthesized by metalorganic chemical vapor deposition with tungsten hexacarbonyl used as a precursor. The mass ratio of precursors was varied to obtain nonstoichiometric tungsten carbide coatings of different morphologies ranging from spatially separated nanoparticles to a uniform ~300-nm-thick coating with a granular structure.

AbstractThe deposition of polyhedral aluminum nanocrystals onto the surface of multiwalled carbon nanotubes (MWCNTs) via metalorganic chemical vapor deposition with the use of triisobutylaluminum as the precursor has been performed for the first time. The new hybrid nanomaterial (Al/MWCNTs) has been characterized by X-ray phase analysis, scanning electron microscopy, and high-resolution transmission electron microscopy. The obtained Al/MWCNTs hybrid materials were tested as the filler for the creation of threedimensional composites on the basis of an AMg2 alloy via powder metallurgy. It has been shown that the use of Al/MWCNTs as the filler increases the hardness of the composites by 18% in comparison with the initial MWCNTs.
