METHOD FOR PRODUCING TITANIUM MICROSPHERES OF NARROW GRADING CONTAINING TITANIUM CARBIDE Russian patent published in 2019 - IPC B22F9/06 C22C32/00 C22B34/12

Abstract RU 2688001 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to the production of titanium carbide-containing titanium microspheres. Surface of the titanium billet is treated with laser radiation. Titanium plate is used as the titanium billet. Surface treatment is carried out under a layer of liquid hydrocarbon in a volume of femtosecond scanning laser radiation of the near infrared range, isolated from atmospheric air, with a power density of about 10¹⁶–10¹⁷ W/m² with the coagulation of the products of ablation in the microspheres.

EFFECT: resulting microspheres have a spherical shape, a smooth surface and contain nanoscale titanium carbide crystallites.
