Ceramic rhaub zirconia ceramic nrog siab hardness

Ceramic rhaub zirconia ceramic nrog siab hardness yog cov khoom siv dav siv hauv ntau yam lag luam xws li aerospace, tsheb, thiab hluav taws xob. Txawm li cas los xij, feem ntau muaj teeb meem tshwm sim thaum siv cov khoom no. Hauv tsab xov xwm no, peb yuav tshawb txog qee yam ntawm cov teeb meem no thiab cov kev daws teeb meem.

Ib qho ntawm cov teeb meem tseem ceeb thaum siv ceramic rhaub zirconia ceramic yog nws nyiam tawg los yog tawg hauv kev ntxhov siab. Qhov no tuaj yeem muaj teeb meem tshwj xeeb hauv cov ntawv thov kub kub qhov twg thermal expansion thiab contraction tuaj yeem ua rau cov khoom ua kom nkig. Txhawm rau txo qhov teeb meem no, cov tuam ntxhab siv cov txheej txheem tsim kho kom txo qis cov ntsiab lus kev ntxhov siab thiab siv cov khoom siv zoo zirconia ceramic nrog qhov tsis zoo.

Lwm qhov kev txhawj xeeb nrog ceramic rhaub zirconia ceramic yog nws cov hluav taws xob conductivity. Zirconia ceramic yog ib qho insulator, uas txhais tau hais tias nws tsis tuaj yeem ua hluav taws xob. Txawm li cas los xij, hauv cov ntawv thov uas tsim nyog siv hluav taws xob, xws li hauv cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob, zirconia ceramic tuaj yeem doped nrog yttria lossis lwm yam ntaub ntawv los txhim kho nws cov conductivity.

Tsis tas li ntawd, qee cov neeg siv yuav pom tau tias cov khoom siv hluav taws xob ceramic zirconia ceramic yog qhov nyuaj rau lub tshuab lossis cov duab. Vim nws cov hardness siab, zirconia ceramic yog resistant rau tsoos machining hom kev kawm, xws li drilling thiab milling. Txawm li cas los xij, niaj hnub tsim cov txheej txheem xws li laser txiav thiab EDM (duab hluav taws xob machining) tau tsim tshwj xeeb rau zirconia ceramics. Cov txheej txheem no tso cai rau kev txiav thiab ua kom zoo ntawm cov khoom kom tau raws li kev thov tshwj xeeb.

Thaum kawg, muaj qhov teeb meem ntawm tus nqi. Zirconia ceramic kuj tseem kim piv rau lwm cov ntaub ntawv, ua rau nws tsis txaus nyiam rau qee cov tuam ntxhab. Txawm li cas los xij, cov khoom siv ua haujlwm ntev thiab kub-kub kuj tuaj yeem muab cov nqi txuag lub sijhawm vim txo qis kev saib xyuas thiab hloov cov nqi.

Hauv kev xaus, thaum muaj qee qhov teeb meem cuam tshuam nrog ceramic rhaub zirconia ceramic, kev nce qib hauv cov ntaub ntawv kev tshawb fawb thiab kev tsim khoom tau ua rau nws muaj txiaj ntsig zoo hauv ntau yam kev lag luam. Nrog rau kev tsim thiab tuav kom zoo, zirconia ceramic tuaj yeem muab kev ua haujlwm zoo thiab ua haujlwm ntev rau ntau yam kev siv.
