Akụkụ seramiiki Zirconia nke Yttria kwadoro – Ike siri ike na nguzogide iyi
St.Cera na-emepụta akụkụ seramiiki zirconia ahaziri ahazi site na iji yttria-stabilized ZrO₂ (Y-TZP). Ihe a na-enye ike flexural pụrụ iche (1000 MPa), ike mgbawa dị elu (5–8 MPa·m¹/²), na ike Vickers nke 13 GPa. Njupụta bụ 6.03 g/cm³, na-enweghị mmiri ọ bụla. Enwere ike inye akụkụ ndị ahụ na agba ọcha ma ọ bụ oji. Usoro ike mgbanwe pụrụ iche nke zirconia na-enye ezigbo iguzogide mgbasa mgbawa, na-eme ka ọ dị mma maka ihe ndị nwere ike imetụta mmetụta, ujo okpomọkụ, ma ọ bụ nrụgide dị elu. Akụkụ ndị a na-ahụkarị gụnyere oche valvụ, plọng mgbapụta, pin nduzi eriri, ngwaọrụ ịkpụ, na bushings na-eguzogide iyi.
Nkọwapụta (dabere na Y-TZP ZrO₂):
| Akụ na ụba | Uru |
| ihe | Zirconia nke Yttria kwụsiri ike |
| Agba | Ọcha na Ojii |
| Njupụta | 6.03 g/cm³ |
| Mmịpụta Mmiri | 0% |
| Nha ọka | 0.4 μm |
| Ike nke Flexural | 1000 MPa |
| Ike Mgbaji | 5–8 MPa·m¹/² |
| Ike Vickers | 13 GPA |
| Modulu nke Young | 200 GPA |
| Ọgbakọ okpomọkụ | 2 W/m·k |

Ngwa:
- · Lelee valvụ na valvụ bọọlụ na mgbapụta kemịkalụ
- · Ntugharị ntuziaka eriri optic ferrule
- · Ntucha na ihe ndị na-eme ka ọ dị mma
- · Ngwa ọgwụ na ngwaọrụ ezé
Mmepụta:
Isostatic pressing → green machining → sintering → CNC grinding → lapping/polishing. Nkwenye ±0.01 mm, elu mmecha Ra ≤0.05 μm.
Uru karịa alumina:
- · Ike mgbanwe dị elu nke 3× (1000 vs 361 MPa)
- · Ike mgbawa dị elu - na-eguzogide mgbawa
- · Nguzogide okpomọkụ ka mma
Nhazi:
Geometrị dị mgbagwoju anya, eriri, na obere oghere (≥0.3 mm).
