Izingxenye Ze-Ceramic Eziqiniswe Yi-Yttria Zirconia – Ukuqina Okuphezulu Nokumelana Nokugqokwa
I-St.Cera ikhiqiza izingxenye ze-ceramic ze-zirconia ezenziwe ngokwezifiso isebenzisa i-yttria-stabilized ZrO₂ (Y-TZP). Lezi zinto zinikeza amandla angavamile okugoba (1000 MPa), ukuqina kokuphuka okuphezulu (5–8 MPa·m¹/²), kanye nobunzima be-Vickers obungu-13 GPa. Ubuningi bungu-6.03 g/cm³, ngaphandle kokumuncwa kwamanzi. Izingxenye zinganikezwa ngombala omhlophe noma omnyama. Indlela yokuqinisa uguquko eyingqayizivele ye-Zirconia inikeza ukumelana okuhle kakhulu nokusabalala kokuqhekeka, okwenza kube kuhle kakhulu ezingxenyeni ezithintekayo, ukushaqeka kokushisa, noma ukucindezeleka okuphezulu. Izingxenye ezijwayelekile zifaka izihlalo zamavalvu, ama-plunger epompo, amaphini okuqondisa i-fiber, amathuluzi okusika, kanye nama-bushings angagugi.
Imininingwane (ngokusekelwe ku-Y-TZP ZrO₂):
| Impahla | Inani |
| Izinto | I-Zirconia eqiniswe yi-Yttria |
| Umbala | Okumhlophe Nomnyama |
| Ubuningi | 6.03 g/cm³ |
| Ukumuncwa Kwamanzi | 0% |
| Usayizi Wezinhlamvu | 0.4 μm |
| Amandla Okugobeka | 1000 MPa |
| Ukuqina Kokuphuka | 5–8 MPa·m¹/² |
| Ukuqina kukaVickers | 13 GPa |
| I-Modulus kaYoung | 200 GPa |
| Ukuqhuba Okushisayo | 2 W/m·k |
| Ukwanda Kokushisa (25-1000°C) | 10.5×10⁻⁶/℃ |
| I-Angle Yokulahlekelwa Kwe-Dielectric | 0.002 |
Izicelo:
- · Hlola ama-valve nama-ball valve kumaphampu amakhemikhali
- · Izikhonkwane zomhlahlandlela we-ferrule ye-fiber optic
- · Ukushaya ngokunemba bese kufa
- · Amathuluzi ezokwelapha namathuluzi amazinyo
Ukukhiqiza:
Ukucindezela kwe-isostatic → umshini oluhlaza okwesibhakabhaka → ukuthungwa → ukugaya nge-CNC → ukugoqa/ukupholisha. Ukubekezelelana ±0.01 mm, ukuqeda kobuso Ra ≤0.05 μm.
Izinzuzo ngaphezu kwe-Alumina:
- · Amandla aphezulu okugobeka angu-3 × (1000 vs 361 MPa)
- · Ukuqina okukhulu kokuphuka - kumelana nokuqhekeka
- · Ukumelana okungcono kokushaqeka kokushisa
Ukwenza ngokwezifiso:
Amajiyometri ayinkimbinkimbi, imicu, kanye nezimbobo ezincane (≥0.3 mm).
