Alumina ceramics hold an irreplaceable position in aerospace, mechanical electronics, and chemical industries due to their low density, high temperature resistance, corrosion resistance, and excellent chemical stability. Txawm li cas los xij, cov kev taw qhia muaj zog ionic thiab covalent bonds hauv lawv cov qauv siv lead ua ua rau cov neeg kho tshuab tsis muaj zog: "siab brittleness thiab tsis tshua muaj toughness." Txhawm rau kov yeej qhov kev tsis zoo no thiab nthuav dav lawv cov ntawv thov hauv siab -kawg teb xws li lub zog tshiab, cov kws tshawb fawb tau tsim ntau yam kev siv zog. Piv txwv li, kev txhim kho ntawm Relay Alumina Ceramic Cheebtsam yuav tsum muaj kev nkag siab tob thiab siv cov txheej txheem hloov kho cov khoom siv siab heev.
Dispersion toughening yog ib qho ntawm cov tswv yim yooj yim tshaj plaws thiab siv dav tshaj plaws, feem ntau muab faib ua cov khoom sib zog ua kom muaj zog thiab cov khoom ua kom muaj zog. Ntxiv cov hmoov uas tsis yog-hlau hmoov xws li TiC thiab SiC nrog siab elastic modulus rau lub matrix tuaj yeem txhim kho qhov siab -kub tawg toughness ntawm cov khoom ceramics; Thaum qhia cov khoom siv hlau xws li Cr thiab Ni tuaj yeem tawg lub zog los ntawm cov txheej txheem xws li yas deformation, tawg bridging, thiab deflection, yog li txhim kho lub zog flexural ntawm cov khoom. Qhov kev ua kom zoo ntawm microstructure no muaj kev taw qhia ncaj qha rau kev txhim kho cov neeg kho tshuab kev ntseeg siab ntawm Kub Kub Metallized Ceramic Relay Cases.
Layered toughening yog tshwm sim los ntawm microstructure ntawm seashells hauv qhov xwm txheej. Los ntawm kev tsim ntau txheej txheej ntawm cov ntaub ntawv nrog sib txawv elastic moduli thiab coefficients ntawm linear expansion nyob rau hauv lub ceramic matrix, ntau yam tsis muaj zog interfaces perpendicular rau kev ntxhov siab tuaj yeem tsim sab hauv. Thaum raug rau sab nraud loads, tawg propagation ntawm cov tsis muaj zog interfaces yuav rov txuas ntxiv thiab deflection, ua rau cov khoom rhiab heev rau qhov tsis xws luag. Lub hauv paus ntsiab lus no tseem siv tau rau kev tsim cov Alumina Relay Ceramic Envelopes rau Cov Tsheb Hluav Taws Xob kom tiv taus cov kev vibrations nyuaj thiab cuam tshuam thaum lub tsheb khiav haujlwm.
Tus kheej-toughening thev naus laus zis siv nyob rau hauv-situ composite txheej txheem kom loj hlob pas nrig- zoo li tus los yog rab koob- zoo li cov nplej nrog loj nam piv nyob rau hauv lub matrix. Txoj kev no zoo tshem tawm cov physicochemical incompatibility ntawm lub matrix theem thiab lub reinforcing theem, xyuas kom meej thermodynamic stability. Rau cov khoom siv uas xav tau kev ua haujlwm siab, xws li EV Alumina Ceramic Housing, tus kheej -toughening thev naus laus zis kom ntseeg tau tias cov khoom tuav tag nrho lub zog zoo thiab tawg tsis kam nyob rau hauv huab cua.
Microcrack toughening siv thermal expansion mismatch los yog theem hloov mus rau induce microcracks, dispersing thiab absorbing zog ntawm lub tawg ntsis. Nyob rau hauv lub ZrO2-toughened Al2O3 system, vim qhov sib txawv ntawm expansion coefficients ntawm cov hais thiab cov matrix, txoj kev tawg propagation yog yuam kom lengthen, ho nce puas ntsoog. Cov txheej txheem no yog qhov tseem ceeb rau kev tsim cov khoom siv ua haujlwm siab EV Alumina Ceramic Relay Housing, zoo tiv thaiv kev tawg sai sai thaum muaj kev kub ntxhov.
Ntawm txhua txoj kev toughening, whisker (fiber) toughening yog qhov zoo tshaj plaws. Externally ntxiv los yog hauv -situ zus whiskers tsis tsuas yog muab cov sab nraud load tab sis kuj dissipate ib tug loj npaum li cas ntawm sab nraud zog los ntawm tawg bridging, deflection, thiab rub- tawm los. Qhov siab no - lub zog tsim qauv zoo kawg nkaus ua tau raws li qhov xav tau nruj ntawm EV Relay Alumina Ceramic Housing High Voltage DC Ceramic Contactor los tiv thaiv arc yaig thiab cov neeg kho tshuab qaug zog.
Nrog rau kev txhim kho thev naus laus zis tas li, cov txheej txheem metallization ntawm alumina ceramics tau loj hlob zoo, muab kev sib txuas hluav taws xob txhim khu kev qha rau ntau yam khoom siv hluav taws xob. Tam sim no, siab - zoo alumina metallized ceramics rau cov ntawv siv hluav taws xob tau dhau los ua cov khoom tseem ceeb hauv cov ntim khoom semiconductor thiab cov khoom siv fais fab.
Cov lus nug nquag
1. Vim li cas EV HVDC Relay Ceramic Housing thiaj li ua rau tawg tawg?
Nws cov qauv sab hauv feem ntau yog tsim los ntawm cov khoom muaj zog ionic thiab covalent bonds, uas ua rau cov yas tsis muaj zog deformation. Thaum cov ntaub ntawv tawg, nws propagates sai, yog li nthuav tawm cov yam ntxwv ntawm pob txha tawg.
2. Qhov twg metallized ceramics rau kev siv hluav taws xob yog txoj kev ua kom zoo tshaj plaws?
Tam sim no, whisker (fiber) toughening yog suav hais tias yog txoj kev ua tau zoo tshaj plaws, txhim kho pob txha tawv tawv los ntawm kev sib tsoo, tawg deflection, thiab rub- tawm los.
3. Nyob rau hauv cov teb twg yog alumina metallization feem ntau siv?
Nws yog dav siv nyob rau hauv siab -voltage relays rau lub zog tshiab tsheb, DC contactors, IGBT modules, lub hwj chim hluav taws xob ntim, sensors, thiab industrial tswj cov khoom.
