Huufarka Caadiga ah ee ku salaysan Alumina - Adkaanta Sare ee Machining Sax ah
Qalabkan faakiyuumka ee ku salaysan alumina waxaa laga sameeyay 99.8% Al₂O₃, kaas oo bixiya dusha siman oo aan dalool lahayn oo leh qaabab jeexdin faakiyuum oo gaar ah. Waxay bixisaa adkeysi gaar ah (modulus Young 380 GPa) iyo fidsanaan (≤3 μm), taasoo ka dhigaysa mid ku habboon shiididda saxda ah, ku dhejinta, iyo jarista waferada semiconductor-ka iyo qaybaha indhaha. Hab-dhaqanka kulaylka sare ee walaxda (32 W/m·k) wuxuu hubiyaa isku mid ahaanshaha heerkulka inta lagu jiro farsamaynta.
Tilmaamaha(oo ku salaysan 99.8% Al₂O₃):
| Hantida | Qiimaha |
| Alaab | 99.8% Alumina (Ceyri) |
| Cufnaanta | 3.93 g/cm³ |
| Xoogga Dabacsanaan | 361 MPa |
| Adkaanshaha Vickers | 16 GPA |
| Modulus-ka Young | 380 GPA |
| Qaboojinta Kulaylka | 32 W/m·k |
| Fidsanaan | ≤3 μm (ka badan 200mm) |
| Dusha sare ee qallafsanaanta (dhinaca jajabka) | Ra ≤0.4 μm |
| Heerkulka ugu Sareeya ee Hawlgalka | 800°C |
Codsiyada:
- · Shiidida dambe ee Wafer (qalafsan oo fiican)
- · Kala-goynta saxda ah ee walxaha jajaban
- · Kala-goynta walxaha dhoobada ah
- · Nadiifinta muraayadaha indhaha
Wax soo saarka:
Kala-goynta saxda ah ee labada dhinac → dheemanka lagu dhejiyo (ikhtiyaar) → wareegsan geesaha → nadiifinta ultrasonic → 100% kormeer fidsan oo leh laysarka interferometer.
Afaa'iidooyinka:
- · Taageerada adag waxay yareysaa leexashada culayska saaran
- · Qaab-dhismeedka daloolada leh ma jiro wax soo saar walxo ah
- · Si fudud loo nadiifin karo (oo la jaan qaadi kara dareeraha iyo masaxidda)
- · Godadka faakuumka oo la habeyn karo (qaab isku xiran, radial ah, qaabab gaar ah)
Cabbirrada la heli karo:
Wareeg: 100mm, 150mm, 200mm, 300mm; laba jibbaaran/laydi marka la codsado.
Waxaan sidoo kale bixinnaa noocyo ku salaysan biraha si loo helo xoog farsamo oo sare.
