Yttria-Stabilized Zirconia Ceramic Parts - Kev Ruaj Ntseg Siab & Kev Tiv Thaiv Kev Hnav
St.Cera tsim cov khoom siv zirconia ceramic tshwj xeeb siv yttria-stabilized ZrO₂ (Y-TZP). Cov khoom siv no muaj lub zog flexural zoo heev (1000 MPa), lub zog tawg siab (5–8 MPa·m¹/²), thiab Vickers hardness ntawm 13 GPa. Qhov ceev yog 6.03 g/cm³, tsis muaj dej nqus. Cov khoom tuaj yeem muab tau hauv xim dawb lossis dub. Zirconia lub tshuab hloov pauv toughening tshwj xeeb muab kev tiv thaiv zoo heev rau kev tawg, ua rau nws zoo tagnrho rau cov khoom uas raug cuam tshuam, thermal shock, lossis kev ntxhov siab siab. Cov khoom ib txwm muaj xws li lub rooj zaum valve, lub twj tso kua mis plungers, fiber guide pins, cov cuab yeej txiav, thiab cov bushings uas tsis yooj yim hnav.

Cov ntawv thov:
- · Tshawb xyuas cov li qub thiab cov pob li qub hauv cov twj tso kua tshuaj
- · Fiber optic ferrule guide pins
- · Precision punches thiab tuag
- · Cov cuab yeej kho mob thiab cov cuab yeej kho hniav
Kev Tsim Khoom:
Isostatic nias → ntsuab machining → sintering → CNC sib tsoo → lapping / polishing. Tolerances ± 0.01 hli, qhov chaw tiav Ra ≤ 0.05 μm.
Qhov zoo dua li Alumina:
- · 3 × lub zog flexural siab dua (1000 vs 361 MPa)
- · Kev tawg siab dua - tiv taus chipping
- · Kev tiv thaiv thermal zoo dua
Kev Kho Kom Haum:
Cov qauv sib xyaw, cov xov, thiab cov qhov me me (≥0.3 hli).
