Cov ntaub ntawv ceramic, feem ntau yog hais txog cov khoom siv ceramics lossis cov khoom siv ceramics siab heev, lawv siv rau hauv ntau qhov chaw lag luam, qhov twg lub zog kho tshuab thiab kev tiv thaiv rau cov zog sab nraud (xws li xeb) yog qhov yuav tsum tau ua haujlwm tseem ceeb. Qhov kev tiv thaiv hnav yog qhov ntsuas kev ua tau zoo tseem ceeb los ntsuas cov khoom siv ceramic. Feem ntau cov neeg siv qhov nyuaj los txiav txim siab qhov kev tiv thaiv hnav thiab lub zog ntawm alumina ceramic cov ntaub ntawv. Ntawd yog, qhov nyuaj dua, qhov zoo dua qhov kev tiv thaiv hnav. Yog li yuav ua li cas sim cov kev ntsuas qhov nyuaj ntawm cov khoom siv ceramics uas tiv taus hnav?
Qhov nyuaj yog ib qho ntawm cov khoom tseem ceeb tshaj plaws thiab feem ntau ntsuas hauv alumina ceramics. Nws tuaj yeem txhais tau tias yog kev ntsuas ntawm qhov kev ntxhov siab ntawm txhua yam ceramic lossis cov khoom siv. Qhov nyuaj piav qhia txog kev tiv thaiv ntawm cov ceramic rau kev tawg, kev hloov pauv, kev sib sau ua ke thiab kev hloov chaw. Feem ntau hais lus, Vickers thiab Knoop txoj kev siv dav dav rau kev sim qhov nyuaj ntawm ceramics. Cov txheej txheem Vickers yog qhov feem ntau. Nws ntsuas qhov nyuaj ntawm ceramics lossis lwm yam khoom siv los ntawm kev ntsuas qhov loj ntawm theqhov uas lub tshuab txiav tawm tso tseg. Nws tsim nyog rau cov khoom me me thiab cov khoom nyias nyias. Nws siv lub tshuab txiav pob zeb diamond thiab lub nra hnyav me me los tsim qhov qhov ntawm cov khoom uas tab tom sim. Tus nqi tawv kuj tseem tuaj yeem ntsuas qhov tob ntawm qhov qhov uas lub tshuab txiav tawm ua rau.
Raws li qhov xav tau sib txawv ntawm kev ua lag luam rau kev ua tau zoo ntawm alumina ceramics, Chemshun Ceramics tsim AL2O3 92%, AL2O3 95%alumina hnav cov khoom siv ceramic uas tiv tausCov ntsiab lus alumina cuam tshuam rau qhov nyuaj ntawm cov khoom siv ceramic rau qee qhov, uas yog, qhov hnav tsis kam. Cov neeg siv khoom tuaj yeem xaiv cov khoom siv ceramics uas hnav tsis kam nrog cov ntsiab lus alumina sib txawv raws li qhov xav tau ntawm qhov chaw ua haujlwm.
