METHOD OF PRODUCING HIGH TEMPERATURE POWDER COMPOSITE MATERIAL BASED ON SILICON CARBIDES AND TITANIUM Russian patent published in 2017 - IPC B22F3/14 B22F3/105 C22C29/02 C22C29/18 

FIELD: chemistry.

SUBSTANCE: invention relates to the production of a composite material based on silicon carbides and titanium, comprising the preparation of a powder mixture consisting of titanium, silicon carbide, and graphite, and mechanically activation of the powder mixture. The powder mixture contains 66 wt % Ti, 17 wt % SiC and 17 wt % C. The mechanical activation of the powder mixture is carried out in a planetary mill at a drum rotation frequency of 240-320 rpm in the irregular mode for 180 min, and then the plasma-spark sintering of the mechanically activated powder mixture is carried out in a vacuum at 1350-1450°C, a pressure of 15-30 MPa, an exposure of 5-8 min, followed by gradual cooling for 1 h.

EFFECT: regulation of the phase content in the composite material is provided.
