METHOD OF PRODUCING COMPOSITE MATERIAL Ti/TiB Russian patent published in 2020 - IPC C22C29/14 B22F3/14 B22F3/18 B22F3/87 

FIELD: technological processes.

SUBSTANCE: invention relates to production of Ti/TiB composite material. Method comprises mixing titanium powder with average particle size of 25±10 mcm and titanium diboride powder, average particle size of which is equal to 4±1.5 mcm, in disk vibration mill at rotor rotational speed of 700 rpm for 60 minutes in medium of ethanol with cooling, and subsequent synthesis of composite material by spark plasma sintering at temperature of 1,000 °C, pressure 40 MPa, for 15 minutes. Mixing of titanium and titanium diboride powders is carried out for 30–60 minutes, while stirring during 50–60 minutes, the grinding set is cooled by liquid nitrogen. Received after spark plasma sintering workpiece of synthesized composite material is subject to deformation-thermal treatment by hot sheet rolling at double-rolling mill at accumulated degree of deformation of 50 % with reduction by one pass of 200 mcm at temperature from 900 to 1,000 °C.

EFFECT: obtaining Ti/TiB composite material with high strength and wear resistance along with sufficient ductility at room temperature.
