Yuav ua li cas kom ua tiav qhov smoothness ntawm alumina ceramics?

Txhawm rau txhim kho qhov tseeb ntawm cov khoom, feem ntau cov ntaub ntawv alumina ceramic yuav tsum tau ua tiav kev ua tiav tom qab sintering kom ua tiav qhov smoothness dua. Txawm li cas los xij, alumina ceramics tsis yog cov ntaub ntawv zoo tib yam tom qab tag nrho. Peb yuav ua li cas zoo dua?
Vim lub siab tawv ntawm alumina ceramic cov ntaub ntawv, nws yog ib qho tsim nyog yuav tsum siv cov khoom sib tsoo nyuaj xws li silicon carbide, B4C, lossis pob zeb diamond rau polishing. Tsis tas li ntawd, lubricity ntawm qhov chaw ntawm alumina ceramic cov ntaub ntawv yuav tsum tau txhim kho ua ntej thaum polishing.
Nyob rau hauv precision machining ntawm alumina ceramic cov ntaub ntawv, feem ntau siv txoj kev yog maj mam polish los ntawm ntxhib mus rau nplua, thiab ces polish rau saum npoo. Thaum polishing, Al203 micro hmoov lossis pob zeb diamond slurry me dua 1 μ m tuaj yeem siv rau kev sib tsoo thiab polishing. Tau kawg, laser ua thiab ua ultrasonic kuj tuaj yeem ua tiav lub hom phiaj ntawm polishing thiab sib tsoo alumina ceramics. Cov txheej txheem saum toj no tuaj yeem txhim kho qhov smoothness ntawm alumina ceramic cov ntaub ntawv, thiab tom qab ntawd lub zog ntawm alumina ceramics tuaj yeem txhim kho los ntawm kev ua, uas yog hu ua alumina ceramic reinforcing technology. Qhov tseeb, cov thev naus laus zis xws li hluav taws xob lub tshuab nqus tsev, cov tshuab nqus tsev nqus, lossis cov tshuaj vapor deposition yog siv los ua kom tawv nqaij ntawm alumina ceramics.
Los ntawm cov txheej txheem no, ib txheej ntawm silicon compound zaj duab xis tuaj yeem tso rau saum npoo ntawm alumina ceramics, thiab alumina ceramics tuaj yeem toughened los ntawm cua sov ntawm 1200-1580 degree Kev xyaum tau ua pov thawj tias kev txhim kho alumina ceramics tuaj yeem txhim kho cov neeg kho tshuab lub zog thiab tau txais ultra -siab zog alumina ceramics ntawm thawj lub hauv paus.
