The present work reported a novel way of direct and quick making nanocrystalline Ti-B/Ti-B-N phases out of amorphous boron powder (B) and crystalline titanium (Ti). Nanopowders were obtained by the synthesis in a hypersonic plasma jet. This method is based on the use of a coaxial magnetoplasma accelerator as a plasma generator. The accelerated plasma jet flew to a working chamber filled in argon in...
The dependences of the microstructure and physical and mechanical properties of ceramic mixtures Si3N4/TiN in the full range of mass ratios of the components were studied. The process of sintering and physical and chemical processes were investigated. In particular, the hardness and density of the material were obtained depending on the ratio of conductive titanium nitride and insulating silicon nitride...
The possibility is shown to obtain a nanodispersed powder with the spherical shape particle and with the equal components distribution in a hypervelocity electrical discharge plasma jet generated by a coaxial magnetoplasma accelerator (CMPA). The developed method allows to obtain: nanodispersed (∼ 50 nm), polymorphic crystalline TiO2 phases with the admixture of cubic TiN by the titanium plasma efflux...
The possibility of plasmodynamic synthesis of nanodispersed cubic boron nitride in hyperhigh speed jet of electrodischarged boron-carbon plasma is demonstrated in this work.
