Litšobotsi tse ka sehloohong tsa Cemented Carbide

undefined


Carbide e entsoeng ka samente ke lisebelisoa tsa alloy tse entsoeng ka motsoako o thata oa tšepe ea refractory le tšepe ea matrix ka mokhoa oa phofo oa metallurgy. Hobane lisebelisoa tse nang le phofo ea metallurgy le mokhoa oa ho lokisetsa li fapane. Litšobotsi tsa carbide e entsoeng ka samente li fapane. A re tšohleng litšobotsi tse ka sehloohong tsa carbide e entsoeng ka samente sehloohong sena.


1. Ha ho na tataiso ho carbide e entsoeng ka samente. Carbide e entsoeng ka samente e entsoe ka phofo ea khatello ea sintering. Hobane ts'ebetso ea ho lahla ha e sebelisoe, ha ho na phapang pakeng tsa sekhahla sa bokaholimo le sebopeho sa ka hare, ka hona ho felisa phapang ea ts'ebetso ea mochine e ka 'nang ea bakoa ke phapang ea bongata.

2. Carbide e entsoeng ka samente ha e na bothata ba phekolo ea mocheso. Mosebetsi oa mochine oa carbide o entsoeng ka samente ha o fetohe ka ho futhumatsa le ho pholile, o susumetsoa feela ke khatello ea mocheso nakong ea ho futhumatsa kapa ho pholile. Ka hona, pele ho ts'ebetso ea carbide e entsoeng ka samente e tlameha ho etsoa pele ho ts'ebetso ea sintering. Ka mor'a ho sintering, e ka sebetsa feela ka lisebelisoa tsa daemane. Ts'ebetso ea mochini oa carbide e entsoeng ka samente e khethoa haholo ke bongata ba cobalt le boholo ba karoloana ea tungsten carbide.

3. Karo-karolelano ea Poisson ea carbide e entsoeng ka samente ke 0.21 ~ 0.24. Ka hona, bophara ba ka hare ba hlobo ea carbide bo na le phetoho e nyenyane haholo ho feta hlobo ea tšepe tlas'a ketso ea ho sebetsana le khatello ea kelello. Kahoo, boholo ba sehlahisoa sa carbide se samente se haufi haholo le boholo ba hlobo.

4. Carbide e na le matla a phahameng a khatello. Likahare tsa cobalt li ka khetholla matla a khatello. Matla a hatellang a lihlahisoa tsa carbide tse entsoeng ka samente tse nang le cobalt e tlase li ka fihla ho feta 6000Mpa, e leng hoo e batlang e le habeli ea tšepe.

5. Carbide e entsoeng ka samente e na le coefficient e tlaase ea ho atolosa mocheso. Batho ba lokela ho nahana ka ntlha ena mabapi le moralo le tlhahiso ea hlobo ea carbide.

6. High mogote conductivity. Thermal conductivity ea cemented carbide e phahame ka makhetlo a mararo ho feta tšepe e sa hloekang.

7. The deformation elastic le deformation ea polasetiki ea carbide e entsoeng ka samente e nyenyane.

8. Tšobotsi e tummeng ka ho fetisisa ea carbide e entsoeng ka samente ke boima ba eona bo phahameng le ho hanyetsa ho apara ho phahameng. Nako ea tšebeliso ea tungsten carbide e telele ho feta tšepe e sa hloekang.


Hajoale, li-carbide tse entsoeng ka samente tse sebelisoang mefuteng ea lapeng li entsoe haholo ka tungsten le cobalt.
