General information
Official name:
Federal State Budgetary Institution of Science Institute of Materials Science of the Khabarovsk Scientific Center of the Far Eastern Branch of the Russian Academy of Sciences
The Institute of Materials Science of the KhFRC FEB RAS was founded in Khabarovsk in 1991 with the aim of ensuring the development of fundamental scientific research and solving applied problems of the Far East region in the field of materials science.
The Institute is working on the creation of new materials based on titanium, aluminum, hard alloys with high cutting characteristics, as well as research in the field of mineral raw materials processing.
Institute of Materials Science of the KhFRC FEB RAS
Main scientific areas:
- Physical, technical, and environmental problems of energy, heat, and mass transfer, thermophysical and electrophysical properties of substances, low-temperature plasma and technologies based on it
- scientific foundations for the creation of new materials with desired properties and functions, including high-purity and nanomaterials..
Main research results:
- Nanostructured WC-Co powders were obtained by grinding and electro erosive dispersion, and the properties of hard alloys sintered on their basis were studied.
- Experimental samples of hard alloy products were obtained using 3D printing.
- The influence of the technological conditions of electric discharge deposition of surface layers in the medium of granules on the properties of coatings from metallic glasses has been established.
- The optimal number of doping cations in A1-nXnB1-mYmO3-d perovskites was found to achieve the maximum catalytic activity in the oxidation of black carbon.
- Quantum-mechanical modelling of the properties of tungsten-containing alloys has been carried out.
- Synthesis of photocatalytic compositions based on solid solutions of SrO/Bi2O3 and SiO2 with modifying additives of rare-earth metals has been carried out and their properties have been studied.
- Mineral concentrates were used to obtain W and Zr containing complex alloyed intermetallic Ni-Al alloys.
Key Research Findings
Installation for electroerosive dispersion of IM KhFRC FEB RAS
Installation to produce nanostructured spherical particles by electro erosive dispersion of tungsten-cobalt alloys and other conductive materials in water and oil.
The method is based on the flow of spark discharges between pieces of the source material during the flow of a current pulse, leading to melting, mixing and rapid crystallization of small portions of the material. As a result, nanostructured particles of predominantly spherical shape are formed. The advantage of the method is the possibility of obtaining spherical nanostructured particles directly from pieces of any conductive materials without additional operations. The resulting powders can be used to produce alloys and coatings by powder metallurgy, additive technologies, and spraying.
Electrospark deposition of hardening coatings in granules (EGD)
Coating by electrospark processing in granules is carried out using electrically conductive granules, which act as a source of material for coating the cathode part through the polar transfer of the substance of the granules as a result of the action of electric discharges.
Advantages of EGD:
- EIL automation;
- processing of a curved surface;
- deposition in one stage;
- low cost of consumables.
Cooperation options:
Application of metal, amorphous, cermet and other coatings with high corrosion resistance, high wear resistance and heat resistance on any metal surface. Creation of installations for applying electrospark coatings in metal granules and mixtures of granules with powders on metal parts of any configuration.
