Cov tshuab ntxhua khaub ncaws ceramic tau ua los ntawm cov khoom siv ua tiav raws li qib zeb. 95% Alumina, 99% Alumina, Silicon Nitride, thiab Yttrium Stabilized Zirconia yog plaub nplua nuj ua kom zoo nkauj uas feem ntau siv. Cov khoom siv thev naus laus zis zoo yog cov khoom siv uas tsis yog xim hlau uas ua rau pom muaj ntau yam khoom sib txawv, suav nrog hluav taws xob rwb thaiv tsev, hnav tsis kam, corrosion tsis kam, thiab tiv taus kub thiab thermal poob siab. Cov ceramics muaj qhov tshwj xeeb uas ua tiav lub cev thiab tshuaj yam ntxwv, tso cai rau lawv kom paub meej txog cov txheej txheem ncua sijhawm tom qab kev ua. Nyob rau tib lub sijhawm, qhov no cais cov kev lag luam ceramics los ntawm cov hlau thiab cov khoom siv roj ntsha rau hauv kev hais txog kev ua haujlwm. Vim tias lawv zoo dua txhua qhov kev ua tau zoo, ceramic tiaj tus txuas los yog ceramic lub xub pwg txuas nrog dav hlau ua cov thawj ua haujlwm nto yog dav siv hauv thawj ntawm tib neeg kev ua neej nyob, kev kho mob, kev tiv thaiv kev tiv thaiv, thiab kev ua tub rog. Nyob rau hauv cov ntawv thov uas tsis tshua nruj raws li qhov yuav tsum tau ua, ceramic spacer washer los yog ceramic lub tes tsho washer tuaj yeem tsim los ntawm cov pwm tsim ncaj qha, uas ua rau muaj peev xwm ua ntau lawm thiab pheej yig tus nqi, ua rau nws tsim nyog rau huab hwm coj thiab siv. Yog tias qhov tseeb thiab qhov roughness yuav tsum siab, cov kev ua haujlwm zoo ntawm lub dav hlau yuav tsum mus txog qib micron ntawm cov qauv duab meej thiab nanometre ntawm qib roughness saum npoo, lossis qib siab dua. Raws li qhov tshwm sim, cov nplauv precision washers dav hlau yuav tsum yog hauv av thiab polished los ntawm CNC cov khoom siv. Ob qho sib tsoo lub log thiab cov abrasive yuav tsum siv zog, thiab feem ntau tsim khoom siv siv khoom siv pob zeb diamond.
