Minaiev M. Acquisition of composite nanostructured vacuum-arc coatings of Ti-TiN / TiON structure and their properties

Research object – physical and technological processes of receipt of multi-layered nanostructural coverages of the systems of Ti-TiN and Ti-TiN/TiON by a vacuum-arc method; the purpose of the study is to finding out of features of receipt of multi-layered composition nanostructural coverages of the system Ti-TiN/TiON a vacuum-arc method, that are high mechanical and corrosive characteristics, establishments of morphology of their surface, mechanical and corrosive descriptions; research methods – the analytical and experimental methods of physics of plasma, gas digit and physics of solid, analytical methods, are used during the explanation parameters of besieging of multi-layered nanostructural coverages of the systems of Ti-TiN and Ti-TiN/TiON, experimental researches were executed with the use of modern equipment and standard control and measuring apparatus; results – the technological process of receipt of multi-layered nanostructural coverages, reasonable parameters of besieging of layer, is worked out, morphology, structure, phase composition, mechanical descriptions and corrosive firmness, is certain, an equipment is worked out for retrofitting of the vacuum-arc setting of "Bulat-6" and device that improves quality coverages; novelty – multi-layered nanostructural coverages of the system Ti-TiN/TiON are first got a vacuum-arc method, that are high mechanical and slushing characteristics; it is set that an offer structure of multi-layered nanostructural coverages of the system Ti-TiN/TiON substantially influences on wearproofness of their surface (firmness is more firmness of multi-layered coverages of the system Ti-TiN in three times), and also on corrosive firmness (speed of corrosion in solution of NaCl presents 6,883 mcg/year, that on two orders exceeds a value for stainless steel); it is shown that in coverage of Ti-TiN/TiON is present three phases: TiN with cube grates as NaCl, α- Ti and oxide to titan TiO2; degree of implementation – results causing of coverages inculcated in technology on metallic dentures for stomatological policlinics on the scientific inculcating enterprise of "ION-2"; the field of application is the treatment of materials is in a medical equipment, aviation and general engineer.
