ʻO ke koʻokoʻo seramika Zirconia ikaika kiʻekiʻe - no nā ʻauamo a me nā punches kikoʻī
ʻO ke koʻokoʻo keramika zirconia a St.Cera i wili pololei ʻia mai ka yttria-stabilized ZrO₂. Hāʻawi ia i ka ikaika flexural kūikawā (1000 MPa), ka paʻakikī haki (5–8 MPa·m¹/²), a me ka paʻakikī Vickers (13 GPa). He ʻano ʻeleʻele a keʻokeʻo paha ke koʻokoʻo, ʻo ka density he 6.03 g/cm³, a ʻaʻohe porosity. ʻO ke anawaena mai 1 mm a 50 mm, ka lōʻihi a hiki i 200 mm, me ka hoʻomanawanui e like me ka ±0.005 mm. Hoʻopau ʻia ka ʻili i Ra ≤0.2 μm. Kūpono no nā noi kiʻekiʻe e like me nā plunger, nā ʻauamo, nā pine dowel, a me nā blanks mea hana ʻoki.
Nā kikoʻī (ma muli o Y-TZP ZrO₂):
| Waiwai | Waiwai |
| Mea Hana | ʻO Zirconia i hoʻopaʻa ʻia e Yttria |
| Ka nui o ka paʻa | 6.03 g/cm³ |
| Ikaika Flexural | 1000 MPa |
| Paʻakikī o ka haki | 5–8 MPa·m¹/² |
| Paʻakikī Vickers | 13 GPa |
| Modulus o Young | 200 GPa |
| Pae Anawaena | 1–50 mm |
| Ka laulā lōʻihi | 5–200 mm |
| Ke ahonui ʻana o ke anawaena | ±0.005 mm |
| Hoʻopau ʻili (lapped) | Ra ≤0.2 μm |
Nā noi:
- · Nā plungers a me nā pistons kikoʻī
- · Nā pine Dowel no ke kaulike ʻana
- · Nā mea hana ʻokiʻoki hakahaka (pahi, ʻokiʻoki)
- · Nā wili hali i nā wahi ʻino
Nā Pōmaikaʻi:
- · ʻAʻole makeneka, pale uila (>10¹³ Ω·mm²/m)
- · Kū i nā kemika huhū (nā waikawa, nā alkalis koe wale nō ʻo HF)
- · ʻAʻohe ʻōpala a ʻaʻohe ʻūlū paha
Hana ʻana:
Nā hakahaka koʻokoʻo sintered → wili ʻana me ke kikowaena ʻole i ke anawaena pololei → lapping/polishing → hoʻomaʻemaʻe ultrasonic. Nānā 100% anawaena me ka micrometer laser.
