Fields or research

  • Nanofragmentation and modification of bulk materials by carbon nanoclusters for improvement of their physical, mechanical and functional properties.
  • Structure study of carbon nanoclusters interactions and phase transitions during consolidation and sintering.
  • Industrial applications of carbon nanoclusters.
  • High pressure - high temperature experimental study of nanosized materials.
  • Bulk ceramic samples sintering, phase transitions and chemical reactions under high pressures.
  • Works on synthesis and application of superhard materials (diamond and cubic boron nitride).
  • Research of transport, calorimetric and mechanical properties of nanostructured compact materials.
  • Development of synthesis procedures for nanostructured, superactive, metastable materials.
  • Development of equipment for the production of metal–carbon clusters at high pressure and temperature, and under intense shear deformation.

We develop and improve the techniques required for cluster production in metal–nanocarbon systems (fullerenes, onions, graphenes, nanotubes, and nanodiamonds). We solve problems related to creating homogeneous mixtures of nanoparticles of various compositions, the production of nanoparticles covered by graphene coatings (onions), the production of clusters from fullerene molecules and metals, and aggregation of the resulting composites.

Double-layer plates of cubic boron nitride - hard alloy.

Cubic boron nitride is the second-hardest natural material.

One of the main methods of cBN application is the use of double-walled plates comprising cBN and a hard alloy. The cBN layer consists of a hard framework of grains, yielding high hardness, wear resistance, and thermal conductivity. The hard alloy substrate has high durability for bending and effectively supports the working layer of the instrument during treatment.

Technological processes developed at FSBI TISNCM for the production of double-walled plates enable the manufacture of products with diameters up to 14 mm and heights up to 16 mm.
