Kev Tswj Xyuas Kev Zoo Rau Aln Tej Hab Tej Huav
Txhawm rau kom muaj kev ntseeg siab ntawm txhuas nitride (aln) cov raj ceramic, nruj siv cov kev tswj hwm zoo tswj tau ua tiav:
Cov Raw Khoom Siv Purity-Tshawb Fawb Ntau dua lossis sib npaug rau 99.5% Aln Hmoov nrog Oxygen (<0.8%) and carbon (<0.05%) content via XRF/XRD analysis to prevent sintering defects.
Density & Porosity–Achieve ≥3.26 g/cm³ (98% TD) using helium pycnometry; reject tubes with >{{0 {0}}. 5% qhib porosity (ib astm c20).
Thermal conductivity-laser flash tsom xam kom ntseeg tau 170-200 w \/ mk ntawm 25 degree, nrog<5% batch variation.
Defishectric lub zog-sim ntawm 15-20 kv \/ hli (iec) roj los xyuas cov microcacks los yog suav nrog.
Qhov ntev ntev-laser micrometers siv ± 5μm precision ntawm sab hauv \/ sab nraud diameters (tseem ceeb rau lub tshuab nqus tsev).
Microstructure-suc \/ Eds tshev rau kev sib cav sib ceg txawv txawv lossis theem theem nrab (piv txwv li, al₂o₃ pawg).
Mechanical Integrity–Weibull modulus >12 Via {{4-}} point khoov kuaj (ISO 14704) qhia meej tias khaus xwm.
Hermeticity - kev ntsuam xyuas Helium los kuaj ntawm <1 × 10 teev rau cov raj nqus tsev.
Lub Teeb Pom Zoo - Dawb Lub Teeb Interferometry Xyuas Txog Ra<0.2μm for high-voltage applications.
Corrosion Ntsuam Xyuas - Autoclave Kuaj (85 Degree \/ 85% Rh, 1000h) siv tau cov dej noo.
Ntawv pov thawj rau Mil-prf -38534}}}}}}} is o1 kom paub kev ntxhov siab rau aerospace \/ Kev Siv Kho Mob. Kev ua phem rau kev sim (1% ntawm cov batches) txuas ntxiv lees paub ntau sib xws.
