Spherical Cast Tungsten Carbide Powder

1. Spherical Cast Tungsten Carbide Powder ke eng?

Spherical cast tungsten carbide powder e na le likaroloana tse bohlooho bo lefifi, tse entsoeng ke ultra high-themperature spheroidization kapa khase ea atomization.

Sebopeho sa kristale sa dendritic se entsoeng ka WC le W2C: sebaka se phahameng sa ho qhibiliha (2525 ℃), boima bo phahameng (HV0.1≥2700), sebopeho sa masiba a phahameng (likahare≥90%), lik'hemik'hale tse tsitsitseng, phallo e ntle haholo, boima bo bongata bo phahameng, le ho hanyetsa ho apara ho phahameng. .

Sehlahisoa sena se sebelisetsoa lisebelisoa tsa matrix tsa oli ea daemane, lisebelisoa tse ka holimo tsa plasma (PTA), lisebelisoa tsa ho tjheseletsa, le li-electrode tse samenteng tsa carbide (terata).

2. Ho e hlahisa joang?

"Spherical tungsten carbide powder" hangata e entsoe ka matla a tloaelehileng a tungsten carbide kapa motsoako oa tungsten (W), tungsten carbide (WC), le carbon (C). Haholo-holo ho na le mekhoa e 'meli ea tlhahiso: (1) motsoako oa phofo ea tungsten e kopantsoeng le tungsten carbide le carbon powder e qhibiliha pele. Motsoako o entsoeng ka ho qhibilihisoa o tla hlahisoa ke ho potoloha ha atomizing kapa ho qhibiliha ha mocheso o phahameng haholo le mokhoa oa atomizing. E fetoha spheroid hore e be likaroloana tse chitja tsa WC nakong ea ts'ebetso e potlakileng ea ho tiisa ka lebaka la tsitsipano ea bokaholimo. (2) Ts'ebetso e 'ngoe e itšetlehile ka phetoho ea phofo e tloaelehileng ea tungsten carbide. Ho fafatsa ka plasma, ho kenya motlakase, kapa ho qhibiliha ha sebōpi sa motlakase ho sebelisoa nakong ea ts'ebetso ea spheroidization ho fumana likaroloana tse ntle tsa WC.

3. Ho thoe'ng ka tšebetso ea eona ea 'mele?

Kakaretso ea khabone e laolehang;

Uniform W2C le WC sebopeho sa mekhahlelo e 'meli;

Matla a manyenyane a phahameng (HV0.1≥2700);

Bohloeki bo phahameng (≥99.9%);

Oksijene e tlase (≤100ppm);

Boima bo phahameng (≥98%);

Sebaka se boreleli;

Ha ho libolo tsa satellite;

Kabo ea boholo ba likaroloana tse tšoanang;

Thepa e ntle haholo ea phallo (≤6.0s/50g);

Boima bo bongata (≥9.5g/cm3);

Boima ba theipi (≥10.5g/cm3).

The cast spherical tungsten carbide powder e na le microstructure ea equiaxed dendrites, joalokaha ho bontšitsoe setšoantšong se ka holimo. Setšoantšo sa SEM se ka tlase se bontša ka ho hlaka sebopeho sa eona sa likaroloana tse teteaneng tse chitja tsa WC. E boloka thepa ea lik'hemik'hale e tsitsitseng, ho feto-fetoha ha maemo le ho thatafala, le ho hanyetsa ho ikhethang ha ho apara / abrasion. Bophahamo ba likaroloana tsa phofshoana e chitja ea WC e tsoa ho 0.025 mm ho isa ho 0.25 mm, e bonts'ang khanya e boputsoa bo lefifi. Boima ba eona bo khethehileng ke 15.8 ~ 16.7 g / cm3 e nang le boima bo fokolang ho tloha 2700 ~ 3300 kg / mm2.

4. Litšebeliso tsa eona ke life?

The cast spherical tungsten carbide powder e sebelisoa haholo bakeng sa lisebelisoa tse thata tsa ho cheka le lisebelisoa tsa ho cheka tsa PDC, HVOF kapa PTA e futhumatsang spray holim'a litulo tsa li-valve kapa liphasejeng tse ka hare, le likoahelo tsa weld holim'a libaka tse shebaneng le flange, joalo-joalo.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
