Abstract
A titanium diboride wettable cathode includes a cold-pressed sintered block of titanium diboride, including a titanium diboride and an additive, the additive including a graphite, a carbon fiber and a titanium nitride; and a coating of titanium diboride, coated on a surface of the cold-pressed sintered block of titanium diboride.
Claims14
A titanium diboride wettable cathode, comprising:
- a cold-pressed sintered block of titanium diboride, comprising a titanium diboride and an additive, the additive comprising a graphite, a carbon fiber and a titanium nitride;
- and
- a coating of titanium diboride, coated on a surface of the cold-pressed sintered block of titanium diboride.
A method for preparing a titanium diboride wettable cathode, comprising:
- mixing a titanium diboride powder, an additive, a water, a dispersant, and a binder to form a slurry, wherein the additive comprises a graphite, a carbon fiber, and a titanium nitride;
- granulating the slurry by spray-drying to obtain a powder;
- performing an isostatic pressing treatment on the powder to obtain a briquette;
- processing and adjusting a shape and size of the briquette, followed by performing a high-temperature degreasing treatment on the briquette at a first temperature and under an inert atmosphere to obtain a degreased briquette;
- sintering the degreased briquette for densification at a second temperature and under the inert atmosphere to obtain a cold-pressed sintered block of titanium diboride;
- and
- plasma-spraying a titanium diboride micropowder, as raw material, onto a surface of the cold-pressed sintered block of titanium diboride to form a coating of titanium diboride, thereby obtaining the titanium diboride wettable cathode.
