Direct dynamic synthesis of nanodispersed titanium nitride in a high-speed pulse electroerosion plasma jet

A possibility has been shown to produce nanodispersed TiN in a high-speed sputter-ion plasma jet generated by a coaxial magnetoplasma accelerator. The process is implemented in a short-time (∼10−3 s) operating cycle of the accelerator with titanium electrodes. The basic consumable is prepared by electroerosion from the surface of accelerating channel. Depending on the specific supplied energy dissipated in the channel powder particles can have both a spherical and an irregular form and sizes from 10 to 300 nm.
