Siab -Lub zog Metallized Ceramic Cheebtsam Technology: Ib Choj Txuas Cov Inorganic Non-metallic Thiab Metallic Ntiaj Teb

Lub mechanism ntawm metallizing ceramic qhov chaw yog heev complex, uas muaj ntau yam physicochemical tshuaj. Thaum lub sij hawm sintering, oxide thiab tsis yog - oxide cov khoom nyob rau hauv metallization slurry undergo diffusion migration, particle rearrangement, thiab yas ntws. Raws li qhov kub thiab txias, cov khoom ua rau cov khoom sib txuas ua ke, uas tom qab ntawd tsim cov kua theem thaum ncav cuag eutectic point. Nyob rau ntawm lub sijhawm no, cov kua iav theem nthuav tawm viscous ntws, tsav cov atoms lossis molecules kom diffuse nyob rau hauv lub zog ntawm lub zog saum npoo, txhawb kev loj hlob ntawm grain thiab pore kaw, thaum kawg ua tiav qhov ntom ntom ntawm txheej metallization. Qhov microstructural evolution ncaj qha txiav txim siab qhov kev ua tau zoo kawg ntawm txheej txheej metallized ceramic.

Cov txheej txheem txheej txheem ntws rau metallized alumina ceramics rau cov khoom siv hluav taws xob yog nruj thiab ceev faj. Ua ntej, lub substrate pretreatment yuav polishing lub pressureless sintered ceramic nto rau kho qhov muag smoothness siv pob zeb diamond polishing muab tshuaj txhuam, kom ntseeg tau ib tug roughness tswj nyob rau hauv 1.6µm. Ultrasonic tu hauv acetone thiab cawv yog siv los tshem tawm cov kab mob ntawm qhov chaw. Qhov thib ob, cov slurry yog npaj los ntawm kev hnyav cov ntaub ntawv raw raws li cov qauv kev tshawb fawb thiab cov pob zeb milling lawv los tsim cov metallization slurry ntawm qhov tsim nyog viscosity. Tom qab txheej txheej thiab ziab, kev tshuaj ntsuam luam ntawv feem ntau yog siv, nrog kev tswj xyuas nruj ntawm qhov muab tshuaj txhuam: ib txheej nyias nyias ua rau kev nkag mus rau hauv cov hlau, thaum tuab tuab heev cuam tshuam rau kev txav chaw. Thaum kawg, qhov tseem ceeb ntawm kev kho cua sov theem yog sintering lub qhuav substrate ntawm qhov kub thiab txias nyob rau hauv ib tug txo qhov cua, cia cov hlau hmoov rau chemically bond nrog lub ceramic nto, tsim ib tug robust metallized txheej. Cov kauj ruam no tsim lub hauv paus rau kev npaj siab - zoo Precision Metalized Ceramics.

Many factors influence the quality of Metalized Ceramics for Electrical Components, with formulation design being a prerequisite. A scientific formulation must balance the ratio of glass phase to metal powder to ensure wettability and bonding strength. Sintering temperature and holding time are another major variable. Based on temperature range, sintering can be divided into four stages: ultra-high temperature (>1600 degree), kub siab (1450-1600 degree), nruab nrab kub (1300-1450 degree), thiab kub tsawg (<1300℃). Excessively low temperatures can prevent the glass phase from diffusing and migrating sufficiently, resulting in poor bonding; excessively high temperatures may cause excessive volatilization or grain coarsening of the metallization layer, leading to decreased strength or even detachment. Furthermore, the microstructure of the metallization layer directly affects welding reliability.

Ib txheej txheej metallization zoo tshaj plaws yuav tsum yog tuab thiab zoo ib yam, tsis muaj qhov sib txuas txuas ntxiv ntawm qhov sib txuas, yog li inhibiting tawg propagation thiab txo solder nkag. Qhov no tseem ceeb tshwj xeeb rau Alumina Metallized Ceramics.

Hmoov particle loj thiab nws cov gradation kuj tseem ceeb heev. Thaum cov hmoov zoo heev muab lub zog saum npoo av, lawv nquag ua rau agglomeration, cuam tshuam rau txheej smoothness; Cov hmoov coarse ntau dhau yuav tsum tau ua kom sov siab dua sintering thiab tuaj yeem ua rau cov khoom siv substrate puas. Ib txhij, txheej txheej txheej thiab thickness tswj ncaj qha cuam tshuam rau zaj duab xis zoo. Tsuas yog los ntawm kev ua kom zoo dua cov kev txwv no tuaj yeem ua tau siab - kev ua tau zoo, siab - purity aluminium precision siab siab ceramic metallization qhov chaw yuav tsum tau npaj kom tau raws li daim ntawv thov hauv cov cheeb tsam huab cua.

Nyob rau hauv cov cuab yeej technology tam sim no, metallized ceramic Cheebtsam yog dav siv nyob rau hauv aerospace, lub zog tshiab tsheb, siab -lub zog lasers, thiab siab - zaus sib txuas lus modules. Txawm hais tias siv los ua cov cua kub dissipation substrates los yog cov khoom siv hluav taws xob insulating, Precision Metallized Alumina Ceramic Cheebtsam qhia tau qhov zoo ntawm qhov tsis zoo. Los ntawm kev txhim kho txuas ntxiv ntawm cov txheej txheem machining precision rau Alumina ceramic qhov chaw, kev lag luam niaj hnub thawb cov kev txwv ntawm cov khoom siv. Nyob rau hauv lub neej yav tom ntej, nrog kev loj hlob ntxiv ntawm kev tsim cov thev naus laus zis, lawv yuav ua lub luag haujlwm tseem ceeb tshaj plaws hauv kev daws cov teeb meem ntawm cov cua kub kub flux ntom ntom kub dissipation, propelling hluav taws xob ntim tshuab rau qhov siab tshiab. Rau Metallized Ceramic daim ntawv thov uas ua raws qhov kev ua tau zoo tshaj plaws, kev paub txog cov txheej txheem metallization tseem ceeb tau dhau los ua tus qauv tseem ceeb rau kev ntsuas lub zog thev naus laus zis ntawm cov tuam txhab tsim khoom.
