Hobaneng ha Lihlahisoa tsa Tungsten Carbide li Honyela Ka mor'a ho Sintering?

Tungsten carbide ke e 'ngoe ea lisebelisoa tse tsebahalang haholo indastering ea sejoale-joale. Fekthering, re lula re sebelisa metallurgy ea phofo ho etsa lihlahisoa tsa tungsten carbide. Ho sintering, u ka fumana hore lihlahisoa tsa tungsten carbide li fokotsehile. Joale ho ile ha etsahala'ng ka lihlahisoa tsa tungsten carbide, 'me ke hobane'ng ha lihlahisoa tsa tungsten carbide li ile tsa fokotseha ka mor'a ho sintering? Sehloohong sena, re tlil'o hlahloba lebaka.

Ho hlahisa lihlahisoa tsa tungsten carbide

1. Ho khetha le ho reka thepa e tala ea 100%, tungsten carbide;

2. Ho kopanya tungsten carbide phofo le cobalt phofo;

3. Ho sila phofo e tsoakiloeng mochining o kopanyang bolo ka mokelikeli o mong joalo ka metsi le ethanol;

4. Fafatsa ho omisa phofo e metsi;

5. Ho kopanya phofo ka libopeho le boholo bo fapaneng ho latela litlhoko tsa bareki. Mekhoa e loketseng ea ho hatella e khethoa ke mefuta le boholo ba lihlahisoa tsa tungsten carbide;

6. Ho tsubella seboping sa mollo;

7. Ho hlahloba boleng ba ho qetela.

Mehato ea lihlahisoa tsa sintering tungsten carbide

1. Ho tlosoa ha moemeli oa ho bōpa le sethaleng sa ho chesa pele;

Mothating ona, mosebeletsi o lokela ho laola mocheso hore o eketsehe butle-butle. Ha mocheso o ntse o eketseha butle-butle, mongobo, khase le solvent e setseng ka har'a tungsten carbide e kopantsoeng e tla fetoha mouoane, kahoo mohato ona ke ho tlosa mochine oa ho bōpa le lintho tse ling tse setseng le ho chesa pele. Sekhahla sena se etsahala ka tlase ho 800 ℃

2. Mokhahlelo o tiileng oa sintering;

Ha mocheso o ntse o eketseha mme o feta 800 ℃, o fetohela mothating oa bobeli. Mokhahlelo ona o etsahala pele mokelikeli o ka ba teng tsamaisong ena.Nakong ena, phallo ea polasetiki e eketseha, 'me' mele o sintered o fokotseha haholo.Ho fokotseha ha tungsten carbide ho ka bonoa ka botebo, haholo ka holimo ho 1150 ℃.

3. Mokhahlelo oa sintering oa mokelikeli;

Nakong ea mohato oa boraro, mocheso o tla eketseha ho fihlela mocheso oa sintering, mocheso o phahameng ka ho fetisisa nakong ea sintering. Ho fokotseha ho phethoa ka potlako ha karolo ea mokelikeli e hlaha ho tungsten carbide 'me porosity ea tungsten carbide e fokotseha.

4. Sethala sa ho pholisa.

Carbide e entsoeng ka samente ka mor'a hore e chese e ka tlosoa sebōping sa sintering 'me ea pholile mocheso oa kamore. Lifeme tse ling li tla sebelisa mocheso oa litšila seboping sa sintering bakeng sa tšebeliso e ncha ea mocheso. Nakong ena, ha mocheso o theoha, ho thehoa microstructure ea ho qetela ea alloy.

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.
