Project summary

Materials play an important role in the scientific and technical progress. Therefore, one of the main tasks of modern materials science is R&D of new materials with high operation and ecological parameters.

Application of refractory compounds gives a great opportunity for solving this problem. These compounds are basic construction materials of structural ceramics. They allow increasing loading and temperature limits of some product operation. The most efficient technological approach for synthesizing refractory compounds is self-propagating high-temperature synthesis (SHS) based on combustion processes of powder exothermic mixtures. The combination of SHS with some technological methods, e.g. compaction of combustion products (SHS compaction technology) has resulted in creation of new technological directions for obtaining composite ceramic materials (CCM) and items from simple and complex refractory compounds. The aim of the Project is development and synthesis of new high-efficient composite materials based on refractory compounds with preset operation characteristics.

For realization of the task we propose new compositions including B4C, TiB2, TiC, SiC, Al2O3, Cr3C2, TiN, NiAl, etc. in various proportions and combinations. It is difficult and expensive to produce such complicated but very promising compounds and items thereof by conventional ceramic technologies. That is why; a two-variation technological chart is presented in the Project as a way of the technological solution of the problem:

  • Combination of SHS with force densification using an original technological scheme of SHS-compaction;
  • Densification at static pressure using new high-efficient phosphate binders specially developed for fine SHS powders.

The basic method of the Project and the main technological approach is realization of the authors’ experience and R&D principals of composition and structure formation of heterophase materials.

High dispersion degree of SHS powders (from nano to microsize) is achieved due to special technological solutions. The scientific and technological innovation potential of the Project is provided by formation of structural materials with the economic and technical characteristics which are 1.5 – 2 times higher than those of the analogs, that means an increase in the operation characteristics and a decrease in the production cost of the items.

The Project consultant is Academician of the Russian Academy of Sciences A.G. Merzhanov, the Head of the Project is Prof. O. Okrostsvaridze (IMM GAS), the assistant to the Head is Dr. T.V. Bavina, (ISMAN RAS). The Project team includes highly skilled scientists, technologists and engineers with remarkable experience in SHS and Materials Science. The team has the required technological equipment.

The result of the Project is development of the technology and obtaining of samples of composite SHS ceramic and cermet materials, as well as preparation for promotion of the Project to the market.
