Nā ʻĀpana Seramika Zirconia Paʻa ʻo Yttria - Paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu
Hana ʻo St.Cera i nā ʻāpana keramika zirconia maʻamau me ka hoʻohana ʻana i ka yttria-stabilized ZrO₂ (Y-TZP). Hāʻawi kēia mea i ka ikaika flexural kūikawā (1000 MPa), ka paʻakikī haki kiʻekiʻe (5–8 MPa·m¹/²), a me ka paʻakikī Vickers o 13 GPa. ʻO ka density he 6.03 g/cm³, me ka ʻole o ka omo wai. Hiki ke hoʻolako ʻia nā ʻāpana i ke kala keʻokeʻo a ʻeleʻele paha. Hāʻawi ka mīkini hoʻoikaika hoʻololi kū hoʻokahi o Zirconia i ke kūpaʻa maikaʻi loa i ka laha ʻana o ka māwae, e kūpono ai no nā ʻāpana i pili i ka hopena, ka haʻalulu wela, a i ʻole ke kaumaha kiʻekiʻe. ʻO nā ʻāpana maʻamau e komo pū me nā noho valve, nā plungers pump, nā pine alakaʻi fiber, nā mea ʻoki, a me nā bushings pale ʻaʻahu.
Nā kikoʻī (ma muli o Y-TZP ZrO₂):

Nā noi:
- · Nā kiwikā nānā a me nā kiwikā poepoe i loko o nā pamu kemika
- · Nā pine alakaʻi ferrule fiber optic
- · Nā kuʻi a me nā make kikoʻī
- · Nā mea hana lapaʻau a me nā mea hana niho
Hana ʻana:
Kaomi ʻana o Isostatic → mīkini ʻōmaʻomaʻo → sintering → wili CNC → lapping/polishing. Nā hoʻomanawanui ±0.01 mm, hoʻopau ʻili Ra ≤0.05 μm.
Nā pono ma mua o ka alumina:
- · 3 × ikaika flexural kiʻekiʻe (1000 vs 361 MPa)
- · ʻOi aku ka paʻakikī o ka haki - kū'ē i ka chipping
- · ʻOi aku ka maikaʻi o ke kūpaʻa ʻana i ka haʻalulu wela
Hoʻopilikino ʻana:
Nā ʻano geometries paʻakikī, nā kaula, a me nā micro-hole (≥0.3 mm).
