Kev Piav Qhia Luv:

Daim iav tiaj tiaj silicon carbide (SiC) yog ib qho khoom siv kho qhov muag zoo tshaj plaws uas tsim los ntawm cov khoom siv SiC ceramic. Nws muaj qhov sib piv zoo heev ntawm qhov hnyav, kev ua haujlwm infrared zoo dua, thiab kev ruaj khov ib puag ncig zoo heev, nws yog qhov kev xaiv zoo tshaj plaws rau cov tshuab kho qhov muag uas xav tau ntau. Piv nrog cov ntaub ntawv ib txwm muaj xws li fused silica, germanium, thiab zinc selenide, daim iav SiC tsis yog tsuas yog ua tau zoo hauv qhov nruab nrab mus rau qhov deb infrared spectrum tab sis kuj muab qhov sib dua, lub zog kho tshuab siab, thiab kev ruaj khov mus sij hawm ntev hauv qab kev ua haujlwm hnyav.

Daim iav no tau siv dav hauv kev thauj khoom hauv aerospace, laser systems, infrared imaging, thiab high-precision metrology.

Cov Nta Tseem Ceeb

Kev ua kom zoo dua ntawm cov qauv sib dua: Kev tsim qauv siab heev nrog cov qauv honeycomb thiab topology txo qhov hnyav yam tsis muaj kev txi lub zog.
Ultra-lightweight: Sib dua li cov iav substrates ib txwm muaj, tseem ceeb rau aerospace thiab mobile platforms.
Siab tawv: Tswj qhov tseeb ntawm daim duab txawm tias muaj qhov qhib loj thiab daim iav nyias.
Kev nthuav dav thermal qis: Lav tau qhov kev ua tau zoo ntawm qhov muag thoob plaws qhov kub thiab txias hloov pauv sai lossis kub heev.
Kev khawb thiab hnav tsis kam: Hardness ze li pob zeb diamond, resistant rau ib puag ncig abrasion.
Kev ua tiav qhov chaw siab: Qhov tiaj tiaj ≤ 1 μm, qhov zoo ntawm qhov chaw tsim nyog rau kev thaij duab thiab kev siv laser.

Cov Kev Zoo ntawm Kev Ua Tau Zoo

Modulus siab & dimensional stability: Elastic modulus txog li 420–450 GPa, ua kom muaj kev ua haujlwm ruaj khov nyob rau hauv cov khoom hnyav thiab kev co.
Kev cuam tshuam thermal tsawg kawg nkaus: Coefficient ntawm thermal expansion (CTE) qis heev, ua kom muaj kev ruaj khov ntawm qhov muag hauv cov chaw kub sib txawv.
Kev poob siab thermal thiab kev tiv thaiv corrosion: Ruaj khov tiv taus cov kua qaub / alkali thiab tiv taus kev hloov pauv sai ntawm qhov kub thiab txias.
Cov qauv me me uas ntom ntom, tsis muaj qhov hws: Qhov ceev ntawm cov khoom yog txog li 3.14 g/cm³ thiab tsis muaj qhov seem tom qab ua tiav, ua rau muaj kev cuam tshuam zoo heev thiab kev ruaj khov ntawm cov qauv.

Cov Lus Nug Feem Ntau

Q1: Daim iav SiC puas yog qhov cuam tshuam rau hauv cov wavelengths pom?
A1: Lub substrate nws tus kheej yog opaque, tab sis nrog cov txheej txheem reflective tsim nyog (hlau lossis dielectric), SiC daim iav tiaj tus tuaj yeem ua haujlwm tau zoo hauv qhov pom, infrared, thiab txawm tias laser wavelengths.

Q2: SiC muaj cov txiaj ntsig zoo li cas rau iav lossis iav hlau?
A2: SiC sib dua, tawv dua, thiab ruaj khov dua li cov iav lossis cov hlau. Nws kuj ruaj khov dua hauv qhov chaw nyuaj lossis qhov chaw.

Q3: Cov iav SiC tiaj tiaj puas siv tau rau hauv cov ntawv thov laser muaj zog heev?
A3: Yog. Nrog rau kev ua tau zoo heev ntawm thermal conductivity thiab kev ruaj khov ntawm cov khoom siv, SiC substrates yog qhov zoo tagnrho rau cov iav laser muaj zog lossis muaj zog thaum ua ke nrog cov txheej txheej tsim nyog.

Q4: Qib twg ntawm qhov tiaj tiaj tuaj yeem ua tiav?
A4: Tom qab kev ua kom tiav ultra-precision polishing, qhov tiaj tiaj tuaj yeem ncav cuag ≤ 1 μm, nrog rau kev sib luag thiab qhov roughness ntawm qhov chaw tswj kom ua tau raws li cov lus qhia kho qhov muag nruj.
