IDEA #9P7FU3 New Trends Of Nanostructure Coating Development

SCIENTIFIC INNOVATIVE PROJECTS FROM MINISTRY OF EDUCATION AND SCIENCE AND NATIONAL ACADEMY OF SCIENCES OF UKRAINE NEW TRENDS OF NANOSTRUCTURE COATING DEVELOPMENT Description: Pioneering deposition technology based on the supersonic active material particles – gaseous(cid:28)vapor flow mixed with the aerosol consist of nano scale liquid metal drops getting from substrate.The technology provides outstanding active material adhesion to substrate, super high efficiency (more than 1 mm per sec.). Suitable for fabrication of epi(cid:28) toxy or porous nanostructure films with the thickness 500 nm – 1 mm. Process efficiency of nanofilm's manufacturing using depo(cid:28) sition methods determines by 2 main factors: – Material quantity transfer from evaporator to the sub(cid:28) strate – Material quantity deposited to the substrate The main originality of PVDS and HDS technology is that material deposition takes place simultaneously with mate(cid:28) rial transfer and deposition rate increasing.Increasing of material mass transfer achieves by using of high(cid:28)pressure gas (vapor) flow with particles of initial material in liquid state (PVDS technology) and gas (vapor) flow with parti(cid:28) cles of initial material in solid state (HDS technology). Innovative Aspect and Main Advantages: PVDS and HDS technologies allow obtaining of high(cid:28)den(cid:28) sity or porous ceramic or ceramic(cid:28)metal coatings of deter(cid:28) mined thickness on metal or ceramic substrates. The rate of deposition is more than 100 μm/sec which is in 100–1000 times greater than in existing vacuum PVD, CVD tech(cid:28) nologies and 10 times greater compare with plasma and coating technologies of material deposition. When compared to conventional deposition methods the PVDS and HDS enables: – The effective deposition of a variety of materials on a variety of substrates; – The elimination of the need for binders while maintain(cid:28) ing outstanding adhesion; – The manufacture of a wide range of film thicknesses with fewer variations in thickness; – The creation of nanostructured thin films having a more uniform surface with fewer surface defects; – a lower cost of production.
