Wonder Garden muab lawv cov Zirconia ceramic cartridge (Zirco ™) thiab kev lag luam tus qauv hlau cartridge rau kev tshawb xyuas thermal ntawm vaporization technologies.Txhawm rau kawm txog kev ua haujlwm ntev thiab thermal degradation ntawm cov qauv, Aliovalent Material Research siv pycnometry, x-ray diffraction, scanning electron microscopy thiab zog dispersive spectroscopy ntawm cov qauv txawv ntawm pristine mus rau degraded (300 ° C thiab 600 ° C).Qhov kev txo qis hauv qhov pom tau tias muaj qhov nce ntxiv rau cov qauv tooj dag ntawm 600 ° C, thaum cov qauv ceramic tsis qhia qhov hloov pauv loj ntawm qhov ntom.
Cov tooj dag siv los ua cov hlau nruab nrab-ncej tau txais oxidation tseem ceeb hauv lub sijhawm luv luv, piv rau cov qauv ceramic.Ceramic center-post tseem pristine vim muaj cov tshuaj lom neeg tsis zoo ntawm nws cov ionic bonding.Scanning electron microscopy tau siv tom qab ntawd kom tau txais cov duab daws teeb meem siab ntawm microscale txhawm rau txheeb xyuas qhov hloov pauv ntawm lub cev.Qhov saum npoo ntawm tooj dag uas tsis yog corrosion resistant thiab tau oxidized tag nrho.Qhov tshwm sim ntawm qhov nce ntawm qhov roughness tshwm sim vim oxidation, ua raws li qhov chaw tshiab nucleation rau ntxiv corrosion uas exacerbated lub degradation.
Ntawm qhov tod tes, cov qauv zirconia tseem zoo ib yam thiab tuaj yeem siv rau cov ntawv thov kub dua.Qhov no qhia txog qhov tseem ceeb ntawm cov tshuaj ionic bonding hauv Zirconia vs metallic bonding hauv Brass centerpost.Lub hauv paus ntsiab lus ntawm cov qauv qhia tau hais tias muaj cov pa oxygen ntau dua hauv cov qauv hlau degraded uas sib haum rau kev tsim cov oxides.
Cov ntaub ntawv khaws tseg qhia tau hais tias cov qauv ceramic yog qhov ruaj khov dua ntawm qhov ntsuas kub siab uas cov qauv tau sim ntawm.
