Ibice bya Ceramic bya Zirconia bya Yttria-Stabilized Zirconia – Ikomeye cyane kandi Irwanya Kwangirika
St.Cera ikora ibice bya keramike bya zirconia byihariye ikoresheje ZrO₂ (Y-TZP) ya yttria-stabilized. Iki gikoresho gitanga imbaraga zidasanzwe zo kuzunguruka (1000 MPa), gukomera cyane kw'ivunika (5–8 MPa·m¹/²), n'ubukana bwa Vickers bwa 13 GPa. Ubucucike ni 6.03 g/cm³, nta mazi akuramo. Ibice bishobora gutangwa mu ibara ry'umweru cyangwa umukara. Uburyo bwihariye bwo gukomeretsa bwa Zirconia butanga ubudahangarwa bwiza bwo kwaguka kw'imyanya, bigatuma iba nziza ku bice bishobora gukubitwa n'inkongi, gushyuha cyane, cyangwa guhangayika cyane. Ibice bisanzwe birimo intebe za valve, pompe plunger, fibre guide pin, ibikoresho byo gukata, n'uduti tudashira.
Ibisobanuro (bishingiye kuri Y-TZP ZrO₂):
| Umutungo | Agaciro |
| Ibikoresho | Zirconia ifite ubushobozi bwo guhagarara neza muri Yttria |
| Ibara | Umweru n'Umukara |
| Ubucucike | 6.03 g/cm³ |
| Kunywa Amazi | 0% |
| Ingano y'ibinyampeke | 0.4 μm |
| Imbaraga zo Kongera Uburemere | MPa 1000 |
| Gukomera kw'imvune | 5–8 MPa·m¹/² |
| Ubukomere bwa Vickers | 13 GPa |
| Modulus ya Young | 200 GPa |
| Ubushobozi bwo gutwara ubushyuhe | 2 W/m·k |
| Kwaguka k'ubushyuhe (25-1000°C) | 10.5×10⁻⁶/℃ |
| Inguni yo Gutakaza Dielectric | 0.002 |
Porogaramu:
- · Reba valve na valve z'umupira mu pompe za chemical
- · Udupira tw'inyuma tw'urukiramende rwa Fiber optic
- · Gukubita ibipfunsi bikarangira
- · Ibikoresho by'ubuvuzi n'ibikoresho by'amenyo
Inganda:
Gukanda isostatic → imashini y'icyatsi kibisi → gusya → gusya CNC → gusya/gusukura. Ubushobozi bwo kwihanganira ± 0.01 mm, imiterere y'ubuso bwa Ra ≤0.05 μm.
Ibyiza ugereranije na Alumina:
- · Ingufu zo kwihuta za 3 × (1000 vs 361 MPa)
- · Gukomera cyane mu kuvunika - birwanya gucikagurika
- · Ubudahangarwa bwiza bw'ubushyuhe
Guhindura:
Ibyerekezo by’imiterere, imigozi, n’imyobo mito (≥0.3 mm).
