Cov phaj ceramic sab hauv uas tiv taus kev sib txhuamFeem ntau yog cov khoom siv tiv taus kev hnav khaub ncaws hauv kev lag luam, tab sis ntau lub tuam txhab ntseeg tias alumina ceramic vuas tsis tiv taus kev cuam tshuam thiab tawg yooj yim. Yog li ua tus tsim khoom siv ceramic tiv taus kev hnav khaub ncaws, cia kuv qhia rau koj, peb yuav ua li cas txhim kho qhov kev tiv taus kev cuam tshuam ntawm cov phaj ceramic tiv taus kev hnav khaub ncaws?
Cov khoom siv tseem ceeb ntawm cov ntaub pua plag ceramic uas peb feem ntau hu ua alumina, nws qhov tawg toughness KIC yog ntau dua 4.8 PA.M 1/2, thiab nws lub zog flexural yog ntau dua 290 Mpa. Piv nrog cov hlau thiab lwm yam khoom siv hlau, nws qhov kev cuam tshuam tsis zoo me ntsis. Txawm li cas los xij, los ntawm qee cov txheej txheem tshwj xeeb, qhov kev cuam tshuam tsis zoo ntawm cov ntaub pua plag ceramic uas hnav-resistant tuaj yeem txhim kho tau zoo heev.
1: Kev tsim qauv ntawm qhov chaw uas muaj cov duab kheej kheej
Cov khoom siv kho tshuab tshwj xeeb ntawm cov pob kheej kheej tuaj yeem faib cov zog cuam tshuam ntawm lub phaj sab hauv kom sib npaug, txo qhov ua tau tias lub phaj sab hauv yuav tawg los ntawm kev cuam tshuam. Nws yog ib txoj hauv kev siv ntau los txhim kho qhov tiv taus kev cuam tshuam ntawm cov phaj ceramic sab hauv uas tiv taus kev hnav.
2: Ua kom thaj chaw roj hmab nto ntau dua
Cov ntaub ceramic uas tiv taus kev hnav feem ntau yog siv ua ke nrog roj hmab. Qhov kev tiv taus kev cuam tshuam ntawm ceramics tsis muaj zog, tab sis roj hmab qhov kev tiv taus kev cuam tshuam muaj zog. Peb tuaj yeem muab qhov zoo ntawm ob qho tib si, siv ceramics rau kev tiv thaiv kev hnav thiab roj hmab rau kev tiv taus kev cuam tshuam.
Txoj kev ua haujlwm tshwj xeeb yog kom pom cov roj hmab ntau dua ntawm qhov chaw ntawm lub liner thaum lub sijhawm vulcanization, xws li tawm qhov sib txawv lossis siv cov ntawv ceramic puag ncig. Nws yuav tsum tau sau tseg tias thaum thaj chaw roj hmab ntawm qhov chaw liner nce ntxiv, thaj chaw ceramic yuav txo qis. Thaum qhov kev tiv thaiv kev cuam tshuam tau zoo dua, qhov kev tiv thaiv kev hnav yuav txo qis. Thaum siv nws, kev txiav txim siab dav dav yuav tsum tau ua raws li cov xwm txheej ua haujlwm tiag tiag.
3: Ntxiv lwm cov ntaub ntawv raw rau alumina rau kev kho mob tawv:
Peb tau tsim cov khoom siv ceramic uas tiv taus hnav tau 22 xyoo thiab muaj kev paub nplua nuj hauv kev tsim cov khoom siv ceramic uas tiv taus hnav thiab kev tshawb fawb thiab kev txhim kho. Chemshun Ceramics Company muaj nws lub chaw tshawb fawb thiab kev txhim kho ceramic ywj pheej. Kev ntxiv qee qhov feem ntawm zirconia rau alumina ceramics tuaj yeem txhim kho qhov kev tiv thaiv ntawm cov khoom siv ceramic uas tiv taus hnav.
Alumina ceramic nws tus kheej muaj qhov tsis kam rau kev cuam tshuam tsis zoo, tab sis los ntawm cov txheej txheem ua haujlwm saum toj no: tsim spherical, roj hmab vulcanized, alumina ceramic toughened zirconia, cov ceramic tiv taus kev sib txhuam muaj kev hloov pauv dav dua.
