Abstract

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 in the air atmosphere; nanodispersed (10 ÷ 40 nm) TiO2 (rutile) crystalline phases with the TiC admixture by the titanium plasma efflux in the CO2 atmosphere; nanodispersed (30÷70 nm) cubic TiN by the titanium plasma efflux in the nitrogen atmosphere; nanodispersed composite powders by using electrodes of the CMPA made of several different metals, mixture of different gases and additional reagents introduction in the high-current discharge plasma jet. The process, including such stages as the electroerosive obtaining of the initial material, the dynamic synthesis, the nanodispersed particles formation, is fully realized in the short term (10-4 ÷ 10-3 sec.) cycle of the accelerator work. The basic initial material is generated by the electric erosion from the CMPA acceleration channel surface.
