Zvikamu zveCeramic zveYttria-Stabilized Zirconia - Kusimba Kwakanyanya & Kuramba Kupfeka
St.Cera inogadzira zvikamu zveceramic zve zirconia zvakagadzirwa ne yttria-stabilized ZrO₂ (Y-TZP). Izvi zvinopa simba guru rekuchinjika (1000 MPa), kusimba kwakanyanya kwekupwanyika (5–8 MPa·m¹/²), uye kuomarara kweVickers kwe13 GPa. Kuwanda kwechinhu ichi i6.03 g/cm³, pasina kunyudzwa kwemvura. Zvikamu zvacho zvinogona kupihwa muruvara ruchena kana rutema. Nzira yeZirconia yekusimbisa shanduko inopa simba rakanaka pakupararira kwematombo, zvichiita kuti ive yakakodzera kune zvikamu zvinogona kukanganiswa, kupiswa nekupisa, kana kumanikidzwa kwakanyanya. Zvikamu zvakajairika zvinosanganisira zvigaro zvevharuvhu, mapombi epombi, mapini ekufambisa fiber, maturusi ekucheka, uye mabushings anodzivirira kupfeka.
Magadzirirwo (akavakirwa paY-TZP ZrO₂):
| Pfuma | Kukosha |
| Zvinhu | Zirconia yakagadzikana neYttria |
| Ruvara | Chena & Dema |
| Kuwanda kwevanhu | 6.03 g/cm³ |
| Kunyudzwa kweMvura | 0% |
| Saizi yeZviyo | 0.4 μm |
| Simba reKuchinjika | 1000 MPa |
| Kusimba Kwekutyoka | 5–8 MPa·m¹/² |
| Kuomarara kwaVickers | 13 GPa |
| Modulus yeYoung | 200 GPa |
| Kufambisa kwekupisa | 2 W/m·k |
| Kuwedzera kwekupisa (25-1000°C) | 10.5×10⁻⁶/℃ |
| Angle yekurasikirwa kweDielectric | 0.002 |
Mashandisirwo:
- · Tarisa mavharuvhu nemavharuvhu ebhora mumapombi emakemikari
- · Fiber optic ferrule guide pini
- · Kunyatsobaya uye kufa
- Zvishandiso zvekurapa nezvishandiso zvemazino
Kugadzira:
Kudzvanya kweIsostatic → green machining → sintering → CNC grinding → lapping/polishing. Kushivirira ±0.01 mm, surface finish Ra ≤0.05 μm.
Mabhenefiti pane Alumina:
- · Simba re flexural rakakwirira ne 3 × (1000 vs 361 MPa)
- · Kusimba kwakanyanya kwekutyoka - kunodzivirira kutsemuka
- · Kudzivirira kupisa kwakanyanya
Kugadzirisa:
Majometri akaomarara, shinda, uye maburi madiki (≥0.3 mm).
