Abstract:

Sintering of composites based on nano-dispersed components of the system Fe-C at high pressures is of considerable interest because of the possibility to obtain improved physical and mechanical properties, in particular hardness and wear resistance. As the nanopowder source was used extracted fullerene soot (Cefs) micropowder and carbonyl iron with a particle size of 5-100 microns in a ratio of 90 wt. % Cefs: 10 wt. % Fe. The paper investigates the possibility of preparing a solid -Fe composite with a predominance of superhard carbon phase and a reflux ratio of the components of iron and carbon. A study of the fine structure of the nanocomposite, the refinement of the phase composition and the degree of disorder of the crystal structure was conducted. In order to study the fine structure of the nanocomposite, refinement of the phase composition and the degree of disorder of the crystal structure, methods of transmission electron microscopy (TEM), electron diffraction in the high resolution, raman spectroscopy and combination scattering spectrometer were used.
