Thepa ea Mechini le 'Mele ea Tungsten Carbide

Tungsten carbide ke motsoako o nang le karolo ea mantlha ea phofo e kenyelletsang tungsten carbide, titanium carbide, le phofo ea tšepe joalo ka cobalt, nickel, joalo-joalo, joalo ka sekhomaretsi, se fumanoang ka mokhoa oa metallurgical. Haholo-holo e sebelisetsoa ho etsa lisebelisoa tsa ho itšeha ka lebelo le phahameng le lisebelisoa tse thata, tse thata, le likarolo tse apereng haholo bakeng sa ho etsoa ha serame, le lisebelisoa tsa ho lekanya.

Mechini le thepa ea 'mele ea tungsten carbide

1. Boima bo phahameng le ho apara ho hanyetsa

Ka kakaretso, pakeng tsa HRA86 ~ 93, e fokotseha ka keketseho ea cobalt. Ho hanyetsa ho roala ha tungsten carbide ke tšobotsi ea eona ea bohlokoa ka ho fetisisa. Lits'ebetsong tse sebetsang, li-carbides li bolelele ba makhetlo a 20-100 ho feta li-alloys tse ling tsa tšepe tse manganga.

2. Matla a phahameng a khahlanong le ho kobeha.

Sintered carbide e na le modulus e phahameng ea elastic, 'me sekontiri se senyenyane ka ho fetisisa se fumanoa ha se le tlas'a matla a ho kobeha. Matla a ho kobeha mochesong o tloaelehileng a pakeng tsa 90 le 150 MPa 'me ha cobalt e phahame, e phahamisa matla a ho thibela ho kobeha.

3. Ho hanyetsa kutu

Hangata e sebelisoa libakeng tse ngata tsa lik'hemik'hale le tse senyang hobane hangata li-carbides ha li na lik'hemik'hale. Lintho tse tsitsitseng tsa lik'hemik'hale. Lintho tse entsoeng ka carbide li na le khanyetso ea asiti, e hanana le alkali, ebile e na le oxidation ea bohlokoa leha e le mocheso o phahameng.

4. Matla a torsional

Palo ea torsion ke makhetlo a mabeli a tšepe ea lebelo le phahameng le carbide ke thepa e ratoang bakeng sa likopo tse sebetsang ka lebelo le phahameng.

5. Matla a hatellang

Limaraka tse ling tsa cobalt carbide le cobalt li na le ts'ebetso e phethahetseng tlasa khatello e phahameng haholo 'me li atlehile haholo lits'ebetsong tsa khatello ea ho fihla ho limilione tse 7 kPa.

6. Ho thatafala

Limaraka tsa carbide tse kentsoeng tse nang le li-binder tse ngata li na le tšusumetso e ntle haholo.

7. Mocheso o tlaase oa ho apara ho hanyetsa

Leha e le mocheso o tlase haholo, carbide e lula e le ntle ho sebetsa 'me e fana ka li-coefficients tse tlase tsa khohlano ntle le ho sebelisa setlolo.

8. Thermoharding

Thempereichara ea 500 ° C ha e ea fetoha 'me ho ntse ho e-na le boima bo phahameng ho 1000°C.

9. High mogote conductivity.

Carbide e entsoeng ka samente e na le conductivity e phahameng ea mocheso ho feta tšepe ea lebelo le phahameng, e ntseng e eketseha ka ho eketseha ha cobalt.

10. Coefficient ea katoloso ea mocheso e batla e le nyenyane.

E tlase ho feta tšepe e phahameng ka potlako, tšepe ea carbon, le koporo, 'me e eketseha ka ho eketseha ha cobalt.
