The Research Center of Engineering Ceramic Nanomaterials (RC ECN) was created in 2011. Its primary focus is the synthesis of various nanoengineering materials of self-propagating high-temperature synthesis (SHS) and solution combustion.
Activity of the Center:
The key purpose of the center is to study the fundamentals of self-sustaining heterogeneous reactions in nanoengineering environments in order to create effective technologies of obtaining new materials in the combustion mode. Training specialists to obtain and study new nanomaterials is an important stage of the project.
The key areas of research are as follows:
- generating ceramic nanopowders by using the method of combustion of activated nanostructured reaction atmospheres;
- obtaining ceramic materials by combining the process of gasless combustion and spark plasma sintering (SPS);
- obtaining ceramic and metallic nanopowders by solution combustion;
- obtaining multi-layer reactive nanofilms by combining the methods of mechanical activation and rolling;
- developing methods of combining refractory and heterogeneous materials, and
- obtaining nanocomposite materials based on metallic pseudoalloys by combining mechanical activation and spark plasma sintering.
Materials and their application:
Development of nanostructured hard plates (SiC and B4C), ceramic materials for cutting tools (Al2O3-SiC, Al2O3-SiC-Si3N4), prototype detectors SiC-Si3N4 (joint efforts with the Kurchatov Institute and CERN) with the pre-established surface and volume electrical resistance for aerospace uses; a compact ceramic material based on HfCxN1-x hafnium carbonitride with the theoretical melting temperature of over 4400 oS was synthesized and obtained.
Development of intermetallide and low-module alloys for 3S printing (Ni-Al, Nb-Al, Ti-Al, Ti-Si, Ti-Nb, Ti-Al-Ni, etc.)
A spectrum of material for creating new catalyst agents, condensers, sensors, gas sensors, metal-dielectric-metal and metal-dielectric-semi-conductor structures, piezo- and thermoelectrics is being developed.
The superalloys based on high entropy materials (Ti-Cu-Al-Ni-Nb, Fe-Ni-Cr-Co-Mn, Ni-Al-Cr-Fe-W(Mo), Hf-Zr-Ta-Nb-Ti and Hf-Zr-Ta-Mo-Ti) are under way.
SHS approaches for the new class of ceramic and high entropy carbides and borides are being developed: (Hf0.2Zr0.2Ta0.2Nb0.2Ti0.2)B2, (Hf0.2Zr0.2Ta0.2Mo0.2Ti0.2)B2 and (Hf0.2Zr0.2Mo0.2Nb0.2Ti0.2)C, (Mo0.2Zr0.2Ta0.2Nb0.2Ti0.2)С
Compounds of high-proof and heterogeneous materials (С-С/C-C, SiC/Al, TiN/TiN, SiC/SiC, C-C/Ti, Ti/Ti, etc.)
Pseudoalloys for vacuum electrocontacts (Cu-Cr, Cu-Mo, Cu-W, Cu-Cr-Mo, Cu-SiC, Cu-Cr-SiC, etc.)
