Annotation The paper describes the features of creating of reinforced with carbon nanotubes composite coatings and existing approaches to the interphase interaction evaluation in massive composite materials with a fibrous form of the strengthening phase. General aspects of the composite material interphase interaction theory are transferred from massive to nanoscale objects. It is noted that for compositions with nanoscale components is difficult to create a controlled organization of chemical interaction on the interphase surface because of the strengthening phase small dimensions, for example, carbon nanotubes. The thickness of a single-walled carbon nanotube is one atomic layer, which practically excludes the possibility of controlled chemical interface interaction of a carbide-forming metal matrix with carbon nanotubes. The problem solution of interphase interaction in nanocomposite materials theoretically substantiated by creating a non-carbide-forming metal (particularly copper) diffusion barrier on the carbon nanotubes surface. The most effective way for a diffusion barrier creating is the condensation of an electrically neutral metal steam on the carbon nanotubes surface. It has been experimentally proved the possibility of creating a copper diffusion barrier as a coating on the interphase surface, which will allow regulating the interaction of the composition metal components with carbon nanotubes.
