Iinxalenye zeCeramic zeZirconia eziZinzisiweyo zeYttria – Ukuqina Okuphezulu kunye nokuxhathisa ukunxitywa
I-St.Cera ivelisa iindawo zeseramikhi ze-zirconia ezenziwe ngokwezifiso isebenzisa i-yttria-stabilized ZrO₂ (Y-TZP). Ezi zinto zinika amandla angaqhelekanga okugoba (1000 MPa), ubunzima bokuqhekeka okuphezulu (5–8 MPa·m¹/²), kunye nobunzima beVickers be-13 GPa. Ubuninzi yi-6.03 g/cm³, kwaye akukho kufuma kwamanzi. Iindawo zinokubonelelwa ngombala omhlophe okanye omnyama. Indlela yokuqinisa utshintsho eyahlukileyo yeZirconia inika ukumelana okuhle kakhulu nokwanda kwee-crack, okwenza ukuba ilungele izinto ezichaphazeleka yimpembelelo, ukutshayiswa kobushushu, okanye uxinzelelo oluphezulu. Iindawo eziqhelekileyo ziquka izihlalo zevalvu, ii-pump plunger, ii-fiber guide pin, izixhobo zokusika, kunye nee-bushings ezingagugiyo.
Iinkcukacha (ezisekelwe kwi-Y-TZP ZrO₂):

Izicelo:
- · Jonga iivalvu kunye neevalvu zebhola kwiimpompo zamakhemikhali
- · Izikhonkwane zesikhokelo se-ferrule ye-fiber optic
- · Ibetha ngobuchule ize itshixe
- · Izixhobo zonyango kunye nezixhobo zamazinyo
Ukuvelisa:
Ukucinezela okungabonakaliyo → ukuchwetheza okuluhlaza → ukucola → ukugawula nge-CNC → ukugoqa/ukupolisha. Ukunyamezelana ±0.01 mm, ukugqitywa komphezulu Ra ≤0.05 μm.
Iingenelo ngaphezu kwe-Alumina:
- · Amandla aphezulu okugoba e-3× (1000 vs 361 MPa)
- · Ukuqina okuphezulu kokuqhekeka - kuyamelana nokuqhekeka
- · Ukumelana ngcono nobushushu
Ukwenziwa ngokwezifiso:
Iijometri ezintsonkothileyo, imisonto, kunye nemingxunya emincinci (≥0.3 mm).
