Cov txheej txheem thiab cov yam ntxwv ntawm zirconia ceramic ua

Cov txheej txheem ua rau zirconia ceramics

Ceramics txhua tus muaj qhov yuav tsum tau ua rau qhov loj thiab qhov tseeb ntawm qhov chaw, tab sis vim yog qhov siab sintering shrinkage tus nqi, qhov tseeb ntawm qhov loj ntawm sintered ceramic lub cev tsis tuaj yeem lav. Yog li ntawd, kev ua haujlwm ntxiv yog xav tau tom qab sintering. Kev ua haujlwm tom qab ntawm zirconia ceramics tau dhau los ua qhov tseem ceeb thiab tseem ceeb txuas hauv kev tsim cov cuab yeej tshwj xeeb ntawm ceramics.

Kev ua haujlwm ntawm zirconia ceramics yog nqa tawm los ntawm kev sib sau ntawm micro deformation lossis tshem tawm cov teebmeem ntawm cov khoom ntawm qhov chaw ua haujlwm. Kev sib raug zoo ntawm cov khoom siv sab hauv lossis qhov tsis xws luag tshwm sim thaum lub sijhawm ua haujlwm txawv nrog tus nqi ua haujlwm thiab qhov tsis sib xws ntawm cov khoom ua tiav, thiab cov txheej txheem ua haujlwm kuj txawv. Muaj ntau txoj hauv kev rau kev ua cov zirconia ceramics raws li qhov kev ua tau zoo sib txawv thiab cov txheej txheem ntawm cov khoom. Txawm li cas los xij, kev ua haujlwm ntawm zirconia ceramics feem ntau yog siv tshuab ua haujlwm.

Cov yam ntxwv ntawm zirconia ceramic ua

1. Ceramics raug suav tias yog cov ntaub ntawv nyuaj thiab nkig: siab hardness thiab lub zog yog ib qho zoo ntawm cov ntaub ntawv ceramic, tab sis lawv kuj tau dhau los ua ib qho kev sib tw loj hauv kev ua cov khoom siv ceramic tom qab.

2. Cov ntaub ntawv ceramic muaj cov conductivity tsawg thiab cov tshuaj lom neeg ruaj khov. Yog li ntawd, cov yam ntxwv ntawm cov khoom siv ceramic yuav tsum raug txiav txim siab thaum lub sijhawm ua haujlwm tom ntej, thiab kev ua haujlwm zoo ntawm cov tshuab hluav taws xob lossis cov tshuaj etching ntawm ceramics tsis tuaj yeem siv feem ntau. Raws li txoj kev sib txawv ntawm kev siv hluav taws xob, lawv tuaj yeem sau tau raws li kev siv tshuab, kev ua tshuaj lom neeg, photochemical processing, electrochemical processing, thiab lwm yam kev ua. Cov txheej txheem machining ntawm cov txheej txheem kev siv tshuab tau muab faib ntxiv rau hauv kev ua haujlwm abrasive, cuab yeej machining, thiab sib tsoo. Ntawm lawv, abrasive machining yog ntxiv muab faib ua kev sib tsoo, ultra precision machining, sib tsoo, ultrasonic machining, thiab lwm txoj kev. Raws li kev ua tau zoo sib txawv, txoj kev ua haujlwm ntawm zirconia ceramics sib txawv.
