METHOD OF PRODUCING TITANIUM CARBOSILICIDE-BASED COMPOSITE Russian patent published in 2017 - IPC B22F3/14 C22C29/00 B82Y30/00 C04B35/645 

FIELD: technological processes.

SUBSTANCE: invention relates to production of titanium carbosilicide-based composite. Method involves preparation of powder mixture consisting of powders of titanium, silicon carbide and graphite and aluminium oxide nanopowder, mechanical synthesis of powdered mixture and cold pressing of mixture. Titanium powder used has particle size 100–300 mcm, silicon carbide powder has particle size of 10–100 mcm and graphite powder has particle size 1–10 mcm. Cold pressing of mixture is carried out at pressure of 300 MPa, cold pressing is followed by plasma-spark sintering at temperature of 1,300–1,500°C and pressure of 30 MPa.

EFFECT: reduced content of impurities of carbides and titanium silicide, reduced porosity of material.
