Metallized Alumina Ceramics Rau Cov Khoom Siv Hluav Taws Xob: Ib Tus Neeg Ua Haujlwm tseem ceeb hauv Kev hloov pauv ntawm cov khoom siv hluav taws xob

Nyob rau hauv lub ntiaj teb kev nce qib ntawm cov khoom siv hluav taws xob sai sai, qhov kev thov rau cov khoom siv uas tuaj yeem tiv taus qhov kub thiab txias, muab cov hluav taws xob rwb thaiv tsev zoo heev, thiab tuav lub zog txhua yam tsis tau siab dua. Nkag mus rau Metallized Alumina Ceramics rau Cov Khoom Siv Hluav Taws Xob, cov khoom siv uas tau txais kev pom zoo hauv kev lag luam rau nws cov khoom tshwj xeeb thiab dav - ntau yam kev siv. Kab lus no delves rau hauv lub ntiaj teb ntawm metallized alumina ceramics, tshawb txog lawv qhov tseem ceeb hauv cov khoom siv hluav taws xob niaj hnub no thiab lawv lub luag haujlwm hauv kev tsav tsheb tshiab rau pem hauv ntej.

Metallised ceramics yog ib chav kawm ntawm cov ntaub ntawv uas ib txheej ntawm cov hlau yog siv rau ceramic substrates, txhim kho lawv cov peev xwm sib txuas nrog cov khoom hlau. Cov txheej txheem no feem ntau cuam tshuam nrog kev tso cov hlau txheej rau ntawm cov khoom siv ceramic, ua raws li siab -kub sintering kom ntseeg tau tias muaj kev sib raug zoo ntawm cov ceramic thiab hlau. Feem ntau siv metallization cov ntaub ntawv muaj xws li molybdenum, manganese, thiab npib tsib xee.

Cov ceramic nws tus kheej, feem ntau alumina (aluminium oxide), muaj cov khoom tshwj xeeb xws li thermal stability, hluav taws xob rwb thaiv tsev, thiab tsis kam mus rau tshuaj corrosion. Cov yam ntxwv no ua rau Metallized Ceramics indispensable nyob rau hauv ntau yam kev siv nyob rau hauv electronics kev lag luam, tshwj xeeb tshaj yog nyob rau hauv lub tshuab nqus tsev electronics, lub hwj chim electronics, sensors, thiab capacitors.

Deposition ntawm Hlau Txheej:Muaj ntau ntau txoj hauv kev rau tso cov hlau txheej ntawm Metallization Ceramic nto. Ib txoj hauv kev zoo tshaj plaws yog kev siv hlau - cov xim pleev xim los yog pastes. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm molybdenum-manganese (Mo-}Mn) metallization, txheej ntawm molybdenum thiab manganese hais, tov nrog iav additives thiab volatile carriers, yog siv rau lub ceramic metallization nto. Cov txheej no tuaj yeem siv los ntawm tes- pleev xim, txau, lossis siv cov txheej txheem neeg hlau.

Sintering:Tom qab txheej txheej hlau tau thov thiab cua- qhuav, cov ceramic raug rho tawm haujlwm hauv qhov chaw tswj tau. Rau Mo-Mn metallization, qhov no feem ntau yog ua tiav hauv qhov chaw ntub dej hydrogen ntawm qhov kub ntawm 1450℃txog 1600℃. Kev kub siab -kev kho kub ua rau cov iav additives yaj thiab khi cov hlau hais rau Metalized Ceramics rau Hluav Taws Xob Cheeb Tsam, ua rau "iav" xim hlau txheej uas feem ntau yog 300 - 500 micro- ntiv tes (7.6 - 12.7 microns) tuab. Cov txheej tuab no ua kom muaj kev sib raug zoo siab ntawm cov txheej txheem metallised thiab ceramic puag.

Ntxiv Plating (yeem):Feem ntau, cov txheej txheem raug rho tawm haujlwm yog tom qab plated nrog lwm cov hlau. Nickel plating yog ib qho kev xaiv. Ib txheej ntawm nickel, feem ntau yog 0.001 - 0.003 ntiv tes (25.4 - 76.2 microns) tuab, yog siv. Cov npib tsib xee-plated High-Lub zog Metallized Ceramic Cheebtsam yog ces sinter- rho tawm dua ntawm 850℃- 950℃nyob rau hauv ib tug qhuav hydrogen cua. Cov kauj ruam kawg no tawm ntawm cov hlau ua tiav uas tuaj yeem yooj yim brazed siv tus qauv braze muab tub lim.

Raws li kev lag luam txuas ntxiv mus, peb lub tuam txhab txaus siab muab ntau yamMetallized Alumina Ceramics rau cov khoom siv hluav taws xobtsim los ua kom tau raws li cov kev cai nruj tshaj plaws ntawm cov khoom siv hluav taws xob niaj hnub no. Peb cov khoom yog tsim los ntawm lub xeev- ntawm-- txuj ci thev naus laus zis thiab raug kuaj nruj kom ntseeg tau tias lawv ua tau raws li cov qauv zoo tshaj plaws thiab kev ua haujlwm zoo.
