Cov txheej txheem txheej txheem ntawm densifying granular ceramic lub cev thiab tsim cov khoom siv hu ua sintering. Sintering yog ib txoj hauv kev tshem tawm cov voids ntawm cov khoom nyob rau hauv lub cev ntawm lub billet, tshem tawm me me ntawm cov pa roj thiab impurities organic teeb meem, thiab cia cov hais kom loj hlob thiab sib xyaw ua ke los tsim cov khoom tshiab.
Hluav taws xob rauv yog dav siv los ua cua sov rau kev tua hluav taws. Ntxiv rau atmospheric sintering, uas tseem hu ua pressureless sintering, kuj tseem muaj cov xovxwm kub sintering thiab kub isostatic pressing sintering. Txawm hais tias tsis tu ncua kub nias sintering nce ntau lawm, cov khoom siv thiab pwm cov nqi siab dhau lawm. Tsis tas li ntawd, vim axial cua sov, qhov ntev ntawm cov khoom raug txwv. Kub isostatic pressing sintering siv high-temperature thiab high-pressure gas li lub siab hloov nruab nrab, uas muaj qhov zoo ntawm uniformly cua sov nyob rau hauv tag nrho cov lus qhia thiab yog heev haum rau sintering complex zoo li cov khoom. Vim nws cov qauv tsis sib xws, cov khoom siv tau zoo dua los ntawm 30-50% piv rau txias nias sintering. Txhim kho los ntawm 10-15% piv rau cov pa kub nias sintering. Yog li ntawd, qee cov khoom muaj nqis ntxiv alumina ceramic lossis cov khoom tshwj xeeb uas xav tau rau kev tiv thaiv hauv tebchaws thiab kev lag luam tub rog, xws li cov kabmob ceramic, cov khoom siv hluav taws xob, cov roj hluav taws xob thiab cov phom phom, raug rho tawm haujlwm siv cov txheej txheem kub isostatic nias.
Tsis tas li ntawd, microwave sintering, arc plasma sintering, thiab nws tus kheej propagating sintering technologies kuj nyob rau hauv txoj kev loj hlob thiab kev tshawb fawb.
Precision machining thiab ntim txheej txheem
Qee cov ntaub ntawv alumina ceramic tseem xav tau kev ua tiav tom qab sintering. Cov khoom uas tuaj yeem siv los ua cov pob txha pob txha yuav tsum tau ua kom tiav qhov chaw siab, zoo li daim iav, txhawm rau kom lubrication. Vim lub siab hardness ntawm alumina ceramic cov ntaub ntawv, nws yog ib qho tsim nyog yuav tsum siv zog sib tsoo thiab polishing cib ntaub ntawv rau precision ua. Xws li SIC, B4C, lossis pob zeb diamond. Feem ntau, kev sib tsoo yog nqa tawm ib kauj ruam los ntawm kev ntxhib mus rau nplua abrasives, thiab qhov kawg saum npoo yog polished. Feem ntau,<1 can be used μ Grind and polish Al2O3 micro powder or diamond paste with a diameter of m microns. In addition, laser processing, ultrasonic processing, grinding, and polishing methods can also be used.
Txhim kho cov txheej txheem ntawm alumina ceramics
Txhawm rau txhim kho alumina ceramics thiab txhim kho lawv cov khoom siv dag zog, cov txheej txheem tshiab alumina ceramics ntxiv dag zog tau raug qhia txawv teb chaws. Cov txheej txheem no yog tshiab thiab yooj yim. Cov txheej txheem txheej txheem tau txais yuav yog siv cov hluav taws xob hluav taws xob lub tshuab nqus tsev, cov txheej txheem lub tshuab nqus tsev lossis cov tshuaj vapor deposition txoj hauv kev ntawm alumina ceramics, tso ib txheej ntawm silicon compound nyias zaj duab xis, thiab kev kho cua sov ntawm 1200 degree txog 1580 degree kom toughen alumina. ceramics.
Lub zog ntawm lub zog ntawm cov khoom siv dag zog ntawm alumina ceramics tuaj yeem ua kom muaj zog ntxiv ntawm cov hauv paus ntsiab lus, ua rau alumina ceramics muaj zog.
