Khoele ea Ceramic ea Zirconia e Matla a Phahameng – bakeng sa Li-Shaft le Li-Punch tse Hlokahalang ka ho Sebetsa
Thupa ea letsopa ea St.Cera ea zirconia e sitsoe ka nepo ho tsoa ho ZrO₂ e tsitsitseng ea yttria. E fana ka matla a ikhethang a ho kobeha (1000 MPa), ho tiea ha ho robeha (5–8 MPa·m¹/²), le ho thatafala ha Vickers (13 GPa). Thupa e na le ponahalo e ntšo kapa e tšoeu, e teteaneng 6.03 g/cm³, 'me ha e na masoba. Bophara ho tloha ho 1 mm ho isa ho 50 mm, bolelele bo fihlang ho 200 mm, ka mamello e tiileng joalo ka ±0.005 mm. Qetello ea bokaholimo e hokahane ho Ra ≤0.2 μm. E loketse lits'ebetso tse nang le ho robeha ho hoholo joalo ka li-plungers, shafts, dowel pins, le li-blanks tsa lisebelisoa tsa ho seha.
Litlhaloso (tse ipapisitseng le Y-TZP ZrO₂):
| Thepa | Boleng |
| Thepa | Zirconia e tsitsitseng ea Yttria |
| Botenya | 6.03 g/cm³ |
| Matla a ho Tenyetseha | 1000 MPa |
| Ho Tiea ha ho Robeha | 5–8 MPa·m¹/² |
| Boima ba Vickers | 13 GPa |
| Modulus ea Young | 200 GPa |
| Bophara ba bophara | 1–50 mm |
| Bolelele ba Nako | 5–200 mm |
| Mamello ea bophara | ± 0.005 mm |
| Qetello ea Bokaholimo (e kopantsoe) | Ra ≤0.2 μm |
Likopo:
- · Li-plunger le li-piston tse nepahetseng
- · Lipini tsa dowel bakeng sa ho lokisa
- · Ho seha dikgeo tsa disebediswa (dithipa, dikgeo)
- · Lirolara tsa ho bea li le libakeng tse senyang
Melemo:
- · E seng makenete, e sireletsang mocheso ka motlakase (>10¹³ Ω·mm²/m)
- · E mamella lik'hemik'hale tse matla (li-acid, li-alkali ntle le HF)
- · Ha ho mafome kapa ho teneha
Tlhahiso:
Likheo tsa thupa e sintered → ho sila ho se nang bohareng ho fihlela bophara bo nepahetseng → ho lahlela/ho bentša → ho hloekisa ka ultrasound. Tlhahlobo ea bophara ba 100% ka micrometer ea laser.
