Hnav cov kav dej ceramic alumina uas tiv taus tau raug txiav los ntawm ntau cov kauj ruam.
Ua ntej tshaj plaws, cov khoom siv raw ntawm cov kav dej alumina ceramic uas tiv taus hnav yog feem ntau yog Al2O3 kev lag luam, uas yog npaj los ntawm bauxite (Al2O3▪3H2O) thiab diaspore. Rau Al2O3 nrog cov kev xav tau purity siab, nws feem ntau yog npaj los ntawm cov txheej txheem tshuaj lom neeg. Thaum lub sijhawm npaj, lub raj alumina ceramic yog ntxiv nrog cov khoom siv ceramic sib xyaw xws li zirconium oxide, silicon oxide, silicon nitride thiab lwm yam hmoov thaum lub sijhawm calcination kom nce nws qhov nyuaj thiab lub zog.
Hauv theem txiav, kev txiav cov kav dej alumina ceramic feem ntau vam khom cov khoom siv ua tiav siab, xws li cov tshuab txiav hlau ceev lossis cov tshuab txiav hlau qeeb. Cov tshuab txiav hlau ceev yog qhov tsim nyog rau kev ua cov kav dej alumina ceramic nrog cov kab uas me dua thiab qhov xav tau ntawm qhov chaw du; thaum cov tshuab txiav hlau qeeb yog qhov tsim nyog rau kev ua cov kav dej alumina ceramic nrog cov kab uas loj dua thiab qhov xav tau ntawm qhov chaw du. Thaum lub sijhawm txiav, yuav tsum tau them sai sai rau lub kaum sab xis txiav thiab qhov ceev txiav kom ntseeg tau tias qhov du thiab raug ntawm qhov chaw txiav.
Tsis tas li ntawd xwb, kev txiav cov kav dej alumina ceramic kuj tseem yuav muaj cov txheej txheem ua tiav xws li kev sib tsoo thiab tig. Cov txheej txheem sib tsoo feem ntau siv lub tshuab sib tsoo. Lub cuab yeej sib tsoo tuaj yeem yog lub log sib tsoo lossis lub log sib tsoo CBN. Nws yog qhov tsim nyog yuav tsum tau them sai sai rau qhov sib tsoo muaj zog thiab lub sijhawm sib tsoo kom ntseeg tau tias qhov du thiab raug ntawm qhov chaw ntawm cov yeeb nkab alumina ceramic. Cov txheej txheem tig feem ntau siv lathes, thiab cov cuab yeej tig tuaj yeem yog cov cuab yeej tig tungsten steel lossis cov cuab yeej tig carbide.
Feem ntau, kev txiav thiab tsim cov kav dej alumina ceramic uas tsis yooj yim hnav yog ib qho txheej txheem nyuaj uas xav tau cov khoom siv ua haujlwm siab thiab kev tswj hwm cov txheej txheem zoo kom ntseeg tau tias qhov zoo thiab kev ua tau zoo ntawm cov khoom kawg.
