| Summary: | Заглавие с экрана Changes in the phase composition of the material achieve regulatory properties in a wide range. The ultradisperse material in this research was obtained by a direct synthesis in the hypersonic high-current electrical discharge plasma arc obtained using a coaxial magneto-plasma accelerator (CMPA). Regulation of the phase composition of the ultradisperse particles in the system Ti-Si-N (was) have been done by measuring the energy released in the CMPA, ceteris paribus. The influence of the CMPA supplied energy on the ultradisperse material phase composition was investigated. X-ray diffraction patterns of the synthesized powders were obtained. The result of research of the phase composition has been identified having three groups of compounds: initial reactants (Si, Ti); transitional phase (TiSi[2], Ti[2]N, etc.) and final product (TiN and Ti[5]Si[3]). Therefore, with increasing supplied energy transitional phase disappears, and the amount of unreacted materials is reduced. Increase in the content titanium nitride caused by increase of titanium surface electrical erosion of the accelerating channel. Availability of the transitional phases is due to lack of supplied energy. |
