Khoom Description
Hlau thiab ceramic brazing yog ib qho txheej txheem sib koom ua ke uas cuam tshuam nrog cov khoom siv hlau (feem ntau yog cov hlau) nrog qhov qis qis dua li cov ntaub ntawv hauv paus. Thaum qhov kub thiab txias, cov hlau muab tub lim no ntub rau qhov chaw ntawm ob qho tib si ceramic thiab hlau, ua rau qhov sib koom ua ke ntawm kev ua haujlwm capillary, thiab thaum txias cov ntaub ntawv muaj zog metallurgical daim ntawv cog lus. Lub hauv paus ntawm cov thev naus laus zis no yog nyob rau hauv kev kov yeej cov kev sib tw sib tw uas tshwm sim los ntawm qhov sib txawv ntawm lub cev thiab tshuaj lom neeg (xws li thermal expansion coefficient thiab siv lead ua qauv) ntawm ceramics thiab hlau. Qhov no feem ntau yuav tsum tau kho metallization ntawm ceramic nto (xws li, txheej, sintering ib txheej hlau) los yog siv cov active muab tub lim hlau (muaj cov ntsiab lus zoo li Ti, Zr) los txhim kho cov weldability ntawm cov ceramic. Txoj kev no ua tiav siab - kev ua tau zoo ntawm kev sib koom ua ke ntawm cov khoom sib txawv thiab ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv kev tsim khoom siab - kawg.

Cov yam ntxwv ua haujlwm
- Mechanical Properties:Lub zog sib koom ua ke siab, uas tuaj yeem ncav cuag ntau dua 70% ntawm cov ceramic nws tus kheej lub zog, nrog zoo tensile thiab shear kuj, tab sis toughness kuj tsawg.
- Thermal Properties:Zoo siab -kub tsis kam; Kev khiav hauj lwm kub nyob ntawm qhov muab tub lim hlau melting point (feem ntau 800℃-1200 degree). Kev tiv thaiv thermal qaug zog yog cuam tshuam los ntawm thermal expansion txuam; residual stress yooj yim tshwm sim yog mismatched.
- Sealing thiab Corrosion Resistance:Yuav ua tiav hermetic los yog lub tshuab nqus tsev sealing nrog ib tug ntom ntom. Cov tshuaj tiv thaiv corrosion muaj zog, tab sis nyob ntawm qhov muab tub lim hlau muaj pes tsawg leeg.
- Hluav taws xob rwb thaiv tsev:Sab hauv ceramic tuav cov rwb thaiv tsev zoo heev, haum rau kev ntim khoom hluav taws xob; lub metallization txheej tsim tuaj yeem tswj cov kev coj ua.
- Kev ntseeg tau:Zoo ntev - lub sij hawm ruaj khov, tab sis cov kab nrib pleb yuav tshwm sim nyob rau hauv huab cua txias.
Cov ntawv thov tseem ceeb
- Electronics thiab Semiconductors:Siv rau kev sib txuas ceramic substrates (piv txwv li, DBC - Direct Bonded Copper) rau cov hlau lead, lub tshuab nqus tsev twj, laser pob sealing.
- Aerospace:Kev tsim cov khoom siv hluav taws xob, cov khoom siv thruster, lub tshuab tiv thaiv thermal, ua rau siab - kub thiab siab - ib puag ncig siab.
- Zog thiab Tshuaj Kev Lag Luam:Siv rau hauv roj cell sealing, insulating qhov chaw rau cov khoom siv hluav taws xob nuclear, corrosion- tiv thaiv cov yeeb nkab txuas.
- Cov cuab yeej kho mob:Kev cog hniav, hlau-cov khoom siv ceramic hauv cov khoom siv duab (xws li, X-ray raj).
- Automotive Kev Lag Luam:High -kub sensors, brazing ntawm ceramic txiav cov cuab yeej thiab cov cuab yeej tuav, lub zog modules rau lub zog tshiab.
- Cov Khoom Siv Tshawb Fawb:Vacuum system Cheebtsam, particle accelerator qhov chaw, txhawb cov qauv rau precision optical li.
