COATING GROUP OF MATERIALS SCIENCE AND PRODUCTION ENGINEERING DEPARTMENT
Brief information about the product range:
Development of technology that allows high-quality and efficient repair and restoration of structural elements of aircraft airframe damaged during operationing.
Development of process of manufacture of high-impedance capsule coatings for resistive sensors.
Development of technology for coating the surface of flat plates and/or cylindrical products (rotation bodies) made of special materials and alloys.
Development of the process for applying heat-resistant protective coatings by vacuum ion-plasma magnetron sputtering on zirconium fuel element shells to improve their performance and durability in emergency situations (accident-tolerant fuel).
Technology for producing sheet-type filter elements with a membrane layer used for:
Fine cleaning of heat carriers immediately in the first and second circuits of TR and BN type nuclear reactors during operation at NPP.
Removing radioactive aerosols (isotopes of cobalt, caesium and iodine) from hot process gas and pressurized ventilation air in nuclear reactor cores, in vacuum drying systems and in "hot" remote operation chambers.
Cleaning of liquid radioactive waste (LRW) involving deposition of radioactive particles on the filter for their containerized disposal.
Retention by the filter membrane, and extraction of valuable components when cleaning hot solutions of alkalis, acids, galvanic effluents, etc.
Thin membrane-separation of toxic and harmful nano-and microparticles from liquid industrial waste for their further containerized disposal.
Fine-cleaning of inert and liquefied gas media, including condensates.
Cleaning of molten salts and low-melting metals.
Nano treatment of boro-ammonia-containing water of the spent fuel storage pool and reloading of spent fuel elements and reactor vessel at nuclear power plants without altering the water chemistry by the method of membrane concentration of mechanical impurities by way of cross-flow or frontal filtration.
Fine cleaning of the working medium (combustion products, natural gas, steam-gas mixture, overheated steam, etc.) from abrasive impurities in turbine installations and NPP turbine expansion engines, which reduces their wear by an order of magnitude, increases the replacement life several-fold, and reduces energy loss.
Brief information about the services provided:
Development of technical recommendations for surface modification and functional surface treatment for corrosion protection, increasing heat resistance, reducing the coefficient of friction of parts and products used by the nuclear and machine-building industries, and for other sectors of economy (housing and utilities, electric power and medicine).
