Zirconia Ceramics Results & Discussion

Cov txiaj ntsig & Kev Sib Tham

Ntau yam kev sim thiab cov txheej txheem ua tus cwj pwm tau raug xaiv los tsom rau thaj chaw tshwj xeeb ntawm kev txaus siab ntawm cov khoom siv.Ua ntej, cua sov thiab tuav ob hom khoom ntawm qhov kub sib txawv tuaj yeem ua rau peb lub tswv yim ntawm qhov kub thiab txias thiab tso cai rau peb nkag siab txog lub peev xwm ntawm cov ntaub ntawv no.Tom qab kev sim degradation tau ua tiav, peb tau nrhiav ntau yam txuj ci los txheeb xyuas cov kev hloov pauv ntawm cov ntaub ntawv muaj pes tsawg leeg. thiab qauv.

Los ntawm kev txiav txim siab cov qauv siv lead ua ntawm cov qauv pristine thiab txheeb xyuas cov dav hlau uas lub zog hluav taws xob muaj hluav taws xob tawg tawg los ntawm, peb tuaj yeem txheeb xyuas cov qauv siv lead ua peb pib muaj.Tom qab ntawd peb tuaj yeem ua qhov ntsuas ntawm cov qauv degraded los txheeb xyuas cov theem tshiab hauv cov qauv degraded.Yog tias cov qauv thiab cov khoom sib xyaw hloov pauv los ntawm cov kev sim degradation no, peb yuav cia siab tias yuav pom ntau qhov sib txawv hauv peb qhov XRD tsom xam.Qhov no yuav muab peb lub tswv yim zoo txog dab tsi oxides yuav tsim nyob rau hauv cov qauv degraded uas tsis muaj nyob rau hauv cov qauv pristine.

SEM, cov txheej txheem uas siv cov khoom siv hluav taws xob los ua cov duab saum npoo ntawm cov qauv, tuaj yeem siv los tshuaj xyuas qhov chaw ntawm cov khoom ntawm qhov kev daws teeb meem siab heev.Kev ntsuas qhov saum npoo tuaj yeem ua rau peb muaj kev daws teeb meem siab rau qhov ua rau cov qauv degraded li cas thaum piv rau cov qauv pristine.Yog hais tias qhov saum npoo qhia tau tias muaj kev puas tsuaj rau cov khoom, ces peb tuaj yeem paub tseeb tias peb yuav tsum tsis txhob siv cov khoom no ntawm qee qhov kub ntawm kev ntshai ntawm khoom tsis ua hauj lwm.Tom qab ntawd EDS tuaj yeem siv los txheeb xyuas qhov sib xyaw ntawm ntau yam tsim nyob rau saum npoo ntawm cov ntaub ntawv no.Peb yuav cia siab tias yuav pom qhov chaw morphology ntawm thaj chaw ntawm cov khoom uas tau dhau los ua oxidation hnyav.EDS tseem yuav tso cai rau peb txheeb xyuas qhov feem pua ​​​​ntawm cov pa oxygen ntawm cov khoom degraded.

Kev ntsuas qhov ntom ntom tuaj yeem ua tiav daim duab tag nrho thiab qhia lub cev hloov pauv hauv cov ntaub ntawv muaj pes tsawg leeg los ntawm kev qhia qhov sib txawv rau ntau qhov kub thiab txias.Peb cia siab tias yuav pom cov kev hloov pauv loj hauv qhov ntom ntom yog tias cov khoom tau dhau los ua qhov kev hloov pauv ntawm lub cev vim qhov kev sim degradation.Cov qauv zirconia ceramic yuav tsum qhia me ntsis kom tsis muaj kev hloov pauv vim qhov ruaj khov ionic bonding hauv cov khoom.Qhov no qiv rau tag nrho zaj dab neeg ntawm cov khoom siv ceramic ntxiv yog cov khoom siv zoo tshaj vim nws tuaj yeem tiv taus qhov kub thiab txias thiab tswj nws cov tshuaj lom neeg muaj pes tsawg leeg thiab kev ncaj ncees.
