Metallized Ceramic Cheebtsam Cov Khoom Siv Hauv Lub Tsheb Hluav Taws Xob Tshiab: Muaj peev xwm siv tau

Hauv tsheb fais fab, siab - cov khoom ntim ntim fais fab ua lub luag haujlwm tseem ceeb hauv kev tswj lub tsheb ceev thiab khaws cia thiab hloov pauv tam sim no thiab ncaj qha tam sim no. Tsis tau siab - zaus thermal cycles ua nruj me ntsis rau cov cua kub dissipation ntawm electronic ntim. Nyob rau tib lub sijhawm, qhov nyuaj thiab ntau haiv neeg ntawm kev ua haujlwm ib puag ncig yuav tsum tau ntim cov ntaub ntawv ntawm Metallized Ceramic Cheebtsam kom muaj cov thermal poob siab zoo thiab lub zog siab los ua lub luag haujlwm txhawb nqa.

Tam sim no, lub ntsiab ceramic substrates uas tau loj heev - tsim thiab dav siv xws li Al₂O₃, BeO, SiC, Si₃N₄, AlN, thiab lwm yam. Ntawm lawv, silicon nitride yog dav pom nyob rau hauv tsev thiab txawv teb chaws raws li zoo tshaj plaws Metallized Ceramics khoom nrog tag nrho cov kev ua tau zoo xws li thermal conductivity thiab siab reliability. Tab sis tag nrho, hais txog cov khoom xws li thermal conductivity, hnav tsis kam, thiab cov khoom siv kho tshuab, Si₃N₄ thiab AlN ceramic substrates tau dhau los ua cov ntaub ntawv tsim nyog rau kev saib xyuas yav tom ntej. 

Kev tswj hluav taws xob thev naus laus zis yog lub cim tseem ceeb los ntsuas qib kev txhim kho ntawm lub zog tshiab -txuag hluav taws xob tsheb. High-voltage DC Ceramic Metallization relays yog cov khoom tseem ceeb ntawm kev tswj hluav taws xob. High-voltage DC lub tshuab nqus tsev relays muaj lub tshuab nqus tsev vacuum kaw nrog hlau thiab ceramics. Ceramic rau Hlau Insulator yog slidably txuas ntawm cov khoom sib txuas thiab cov pas nrig. Qhov no ua rau cov kev txav mus los thiab zoo li qub nyob rau hauv cov hluav taws xob zoo hluav taws xob nrog lub tshuab hluav taws xob sib nqus tsim los ntawm cov khoom xws li relay cov hlau nplaum hlau nplaum thiab hlau cores, txawm tias lawv nyob los yog tawm. Qhov no ua kom lub relay lub arc - tawg muaj peev xwm thaum hloov siab -voltage DC loads. Arcs yog lub ntsiab ua rau lub tsheb spontaneous combustion. Tsuas yog cov khoom xa tawm nrog "arc-dawb" hloov pauv tuaj yeem daws qhov teeb meem ntawm "spontaneous combustion".

Tam sim no, raws li kev lag luam tsheb txuas ntxiv txhim kho thiab tib neeg cov kev xav tau ntawm cov tsheb nyob rau hauv cov nqe lus ntawm kev tiv thaiv ib puag ncig, kev siv hluav taws xob, kev nyab xeeb, thiab kev nplij siab nce ntxiv, cov khoom siv tsheb kuj hloov tas li. Tshwj xeeb tshaj yog nyob rau hauv nthwv dej ntawm hluav taws xob, kev tsim qauv ntawm lub tsheb tau dhau lub ntiaj teb - hloov pauv. Advanced Ceramic Metallization cov ntaub ntawv yog maj mam tshwm sim nyob rau hauv daim ntawv thov ntawm tshiab zog tsheb qhov chaw.

Advanced Metalized Ceramic cov ntaub ntawv yog tsim los ntawm ionic los yog covalent bonds. Yog li lawv muaj cov khoom zoo xws li lub zog siab, siab hardness, kub tsis kam, hnav tsis kam, corrosion kuj, thiab zoo biocompatibility. Tab sis vim tias feem ntau cov hmoov ceramics yog cov ionic lossis covalent compounds, cov txheej txheem sintering ib txwm ua rau cov khoom siv ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom cov txheej txheem sintering cov txheej txheem ua cov txheej txheem sib xyaw ua ke. Qhov no inevitably ua rau grain coarsening thiab residual pores, uas nyob rau hauv lem cuam tshuam rau kev ua tau zoo ntawm cov ntaub ntawv ceramic.

Txhawm rau daws cov teeb meem zoo li no, sintering yog qhov txuas tseem ceeb tshaj plaws. Tam sim no, yuav ua li cas kom ua tiav cov ntaub ntawv ceev ceev ntawm qhov ntsuas kub qis dua, thiab tsim cov khoom siv ceramic uas muaj qhov pore tag nrho -dawb, muaj cov qauv zoo, cov nplej zoo, thiab ntxiv dag zog rau cov ciam teb, tseem yog lub hom phiaj mus tas li los ntawm Metallized Ceramics cov kws tshawb fawb. Kev tsim kho tshiab ntawm cov khoom siv ceramic sintering thiab thev naus laus zis yog qhov tseem ceeb tshaj plaws los txhim kho kev ua tau zoo ntawm cov khoom siv ceramic siab.

Nyob rau hauv cov ntsiab lus no, peb cov Ceramic Metallizations sawv tawm raws li ib qho kev daws teeb meem tseem ceeb. Cov khoom no ua ke cov khoom zoo tshaj plaws ntawm cov ceramics siab heev nrog kev ua haujlwm ntawm cov hlau, ua rau lawv zoo heev rau qhov xav tau ib puag ncig ntawm lub zog tshiab. Lawv tuaj yeem siv tau rau hauv high-voltage hluav taws xob ntim khoom, qhov twg lawv cov thermal conductivity siab- tau los ntawm cov khoom siv hluav taws xob zoo xws li Si₃N₄ thiab AlN- ua kom cov cua sov tau zoo thaum lub sij hawm siab - zaus thermal cycles. Lawv cov neeg kho tshuab muaj zog thiab tsis kam tiv thaiv thermal shock kuj ua rau lawv zoo tagnrho rau kev txhawb nqa thiab tiv thaiv cov tub ntxhais hluav taws xob hauv cov haujlwm ua haujlwm nyuaj.

Ntxiv mus, pebMetallized Ceramic Cheebtsamyog tsim los siv advanced sintering technologies uas hais txog cov teeb meem ntawm cov txheej txheem ib txwm muaj. They achieve high densification at relatively lower temperatures, resulting in fine and uniform grains with minimal pores. Qhov no tsis tsuas yog khaws cov txiaj ntsig zoo ntawm ceramics tab sis kuj ua kom muaj kev ua tau zoo ib yam, ua rau lawv muaj kev ntseeg siab rau ntau yam tseem ceeb hauv tsheb tshiab. Raws li kev lag luam tsheb txuas ntxiv mus rau kev siv hluav taws xob, peb cov Metallization Ceramics tau npaj los ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua tau zoo, kev nyab xeeb, thiab kav ntev ntawm lub zog tshiab.
