Sebakeng sa thepa ea indasteri, carbide e entsoeng ka samente le tšepe ke libapali tse peli tsa bohlokoa. Ha re arole liphapang tsa bona ho latela litekanyo tsa bohlokoa ho u thusa ho utloisisa hore na o sebelisa e 'ngoe le e 'ngoe neng!
I. Tlhahlobo ea Tlhamo
Thepa ea thepa e tsoa ho liqapi tsa tsona - mona ke kamoo tsena tse peli li bokellanang kateng:
(1) Sebopeho sa Cemented Carbide
- Sebopeho sa mantlha: E entsoe kametsoako e thata (mohlala, tungsten carbide, titanium carbide)le atšepe e kopanyang (hangata cobalt).
- Lebaka Leo e Leng Bohlokoa:
- Lik'hemik'hale tse thata li fana ka boima bo feteletseng le ho hanyetsa ho apara.
- Thepa e kopanyang e "khomarela" metsoako ena, e eketsa boima bo lekaneng ho qoba ho brittleness.
(2) Sebopeho sa tšepe
- Sebopeho sa mantlha: Haholo-holo tšepe (Fe) kakhabone (C)le metsoako ea boikhethelo ea motsoako (mohlala, manganese, chromium, nickel).
- Lebaka Leo e Leng Bohlokoa:
- Likahare tsa carbon li khanna ho thatafala / matla (khabone e phahameng = e thata, empa e fokotsehile).
- Lintho tsa alloying li etsa thepa ka mokhoa o ikhethileng: Chromium e matlafatsa khanyetso ea kutu; nickel e eketsa boima ba 'mele.
II. Pontšo ea Ts'ebetso
Ha re bapise litšobotsi tsa bona tsa mantlha tsa mochini le tsa 'mele:
| Thepa | Carbide e entsoeng ka samente | Tšepe |
|---|---|---|
| Ho thatafala | E phahameng haholo (HRA 89–93, ~HRC 74–81) | E itekanetseng (HRC 20–65, ho itšetlehile ka kereiti) |
| Apara Resistance | E ikhethang (e ntša tšepe ka har'a abrasion) | E ntle (empa e hloleha kapele lits'ebetsong tse apereng haholo) |
| Mathata | E tlase (e brittle; e tloaetse ho petsoha tlas'a tšusumetso) | E phahame (ea tenyetseha; e nka lintho tse tšosang) |
| Ho hanyetsa Mocheso | E boloka boima ho fihlela ho 800-1000 ° C | E lahleheloa ke matla ka holimo ho 400 ° C (bakeng sa tšepe e hlakileng) |
| Khanyetso ea Corrosion | E nepahetse libakeng tse ikhethileng (mohlala, mochini o omileng) | E hloka li-alloys (mohlala, tšepe e sa hloekang) bakeng sa khanyetso e ntle |
Tšusumetso ea Sebele ea Lefatše ea Likheo tsa Ts'ebetso
- Carbide ea Cemented e Khanyalithulusing tsa ho seha (mohlala, likotoana tsa ho phunya) le merafong—moo mocheso o feteletseng o renang teng.
- Lisebelisoa tsa tšepeka likarolo tsa sebopeho (mohlala, liforeimi tsa koloi, marokho) - moo ho thatafalang le matla a baballang chelete a bohlokoa.
III. Libaka tsa Kopo
Liphapang tsa bona tsa ts'ebetso li ba kenya likarolo tse ikhethang:
(1) Likopo tsa Carbide tse tiisitsoeng
- Lisebelisoa tsa ho Seha: Li-cutters, li-drill bits (li sebetsana le ho itšeha ka lebelo le phahameng).
- Morafo/Ho cheka: Malebela a ho phunya mafika, lisebelisoa tse phunyang kotopo (e hanela mafika a hlabang).
- Sepakapaka: Likarolo tse nepahetseng (mohlala, likarolo tsa turbine) tse hlokang ho hanyetsa mocheso / ho apara.
(2) Lisebelisoa tsa tšepe
- Kaho: Rebar, maballo (e itšetlehile ka matla + ductility bakeng sa polokeho).
- Tsa makoloi: Chassis, likarolo tsa enjene (ho leka-lekanya matla, ho tiea, le litšenyehelo).
- Mechini e Akaretsang: Li-gears, shafts (tse fapa-fapaneng ho pholletsa le khatello e tlase ho ea holimo).
IV. Litšenyehelo tsa Tlhahiso le Ts'ebetso
(1) Papiso ea Litšenyehelo
- Carbide e entsoeng ka samente: E bitsa chelete e ngata ka lebaka la:
- Lisebelisoa tse sa tloaelehang (tungsten, cobalt).
- Metallurgy e rarahaneng ea phofo (ho hatella + sintering).
- Tšepe: E fumaneha ka lebaka la:
- Tšepe/khabone e ngata.
- Tlhahiso e holileng (ho qhibilihisa, ho thella).
(2) Bothata ba ho sebetsa
- Carbide e entsoeng ka samente: Ho thata ho mochine-ho hloka EDM (machining ea ho ntša motlakase) kapa laser cutting.
- Tšepe: Ho bonolo ho bōptjoa—e fereka, ea phuthoa kapa ea seha ka lithulusi tse tloaelehileng.
V. Joang ho Khetha?
Khetha ho latela:
- Tikoloho:
- Mocheso o phahameng / abrasion? → Carbide e entsoeng ka samente.
- Matšoenyeho/ litlamorao? → Tšepe.
- Litlhoko tsa Ts'ebetso:
- Bothata bo feteletseng? → Carbide e entsoeng ka samente.
- Ductility/mathata? → Tšepe.
- Tekanyetso:
- E na le litšenyehelo? → Tšepe.
- Tshebetso e lokafatsa premium? → Carbide e entsoeng ka samente.
Qetello: Khetha ka Bohlale Bakeng sa Litlhoko tsa Hao
Carbide e entsoeng ka samente le tšepe ha se li qothisanang lehlokoa le tsona - ke lisebelisoa tse khethehileng. Sebelisa carbide bakeng sa maemo a feteletseng; tšetleha ka tšepe bakeng sa matla a mangata, a theko e boima.
Na u nahanne ka morero? Arolelana litlhoko tsa hau ho maikutlo, 'me ha re qoqa ka lisebelisoa tse ntle ka ho fetisisa!
