Taw qhia rau Porcelain Bushing

Kev ruaj khov ZrO2 cov ntaub ntawv ceramic muaj cov pa oxygen ion zoo, tshuaj lom neeg ruaj khov, thiab zoo thermal stability nyob rau hauv high-temperature ib puag ncig, ua rau lawv dav siv cov khoom siv electrolyte hauv kev lag luam oxygen sensor. Nrog rau kev nce qib ntawm cov thev naus laus zis hauv kev lag luam steel, qhov kev thov rau zirconia ceramic tes tsho hauv thermal engineering xws li steelmaking thiab metallurgy tseem nce ntxiv. Txawm li cas los xij, qhov loj me ntawm cov khoom lag luam tau dhau los ua ntau dua, kev siv ib puag ncig tau xav tau ntau dua, thiab cov pa oxygen rhiab heev thiab thermal stability ntawm cov ntaub ntawv kuj siab dua. Ib feem loj ntawm cov zirconia ceramic tes tsho tseem yuav tsum tau xa tuaj, feem ntau yog vim qhov tsis ruaj khov ntawm cov khoom siv hauv tsev thiab tsis muaj kev sib tw muaj zog ntawm tus nqi. Los ntawm kev xav ntawm kev tsim technology, nws yog ib qho nyuaj rau kev tswj cov txheej txheem ntawm zirconia ceramics thiab txhim kho lawv cov kev ua tau zoo. Zirconia cov ntaub ntawv lawv tus kheej muaj cov yam ntxwv ntawm polycrystalline transformation. Thaum rhuab, monoclinic zirconia yuav hloov mus rau tetragonal zirconia ntawm 1000-1100 degree, nrog rau ntim shrinkage ntawm 7% mus rau 9%; Thaum txias txias, tetragonal crystalline zirconia tau hloov pauv mus rau monoclinic zirconia ntawm 700-900 degree, nrog rau qhov loj ntim nthuav dav. Qhov no ua rau nws yooj yim rau lub tes tsho zirconia ceramic kom tawg thiab deform thaum lub sijhawm tua, thiab cov khoom ua haujlwm tsis ua raws li cov kev cai, uas ua rau muaj qhov tsis zoo xws li thermal stability, mechanical zog, thiab tsis zoo geometric qhov ntev ntawm lub tes tsho ceramic.
Los ntawm kev sim ntawm kev sib piv thiab kev xaiv ntawm 8mol% Y2O3 stabilized ZrO2 ceramic raw cov ntaub ntawv, isostatic nias pwm tsim, tsim cov txheej txheem, kev xaiv cov khoom siv hluav taws xob, thiab cov txheej txheem tua hluav taws, tawg, eccentricity, deformation, thiab loj sib txawv ntawm cov khoom thaum lub sij hawm txoj kev loj hlob. raug tshuaj xyuas thiab kawm. Lub tes tsho ruaj khov zirconia ceramic nrog kev ua haujlwm zoo yog tsim, thiab cov txheej txheem ntws tau raug kho thiab txhim kho kom nce cov khoom tsim nyog tus nqi
