Kukonzekera kwa SIC zokutira

Pakali pano, kukonzekera njira zaKupaka kwa SiCmakamaka zimaphatikizapo njira ya gel-sol, njira yophatikizira, njira yokutira burashi, kupopera mbewu mankhwalawa kwa plasma, njira yamankhwala a vapor reaction (CVR) ndi njira yopangira mpweya wamankhwala (CVD).

Njira yosinthira
Njira iyi ndi mtundu wa kutentha kwamphamvu kwambiri, komwe kumagwiritsa ntchito ufa wa Si ndi C ngati ufa woyikira, imayikagraphite matrixmu embedding ufa, ndi sinter pa kutentha mu mpweya inert, ndipo potsiriza amapezaKupaka kwa SiCpamwamba pa matrix a graphite. Njirayi ndi yosavuta, ndipo zokutira ndi masanjidwewo zimalumikizidwa bwino, koma ❖ kuyanika kofanana ndi makulidwe ake ndikosavuta, ndipo ndikosavuta kutulutsa mabowo ambiri, zomwe zimapangitsa kukana kwa okosijeni kosakwanira.

Njira yokutira burashi
The burashi ❖ kuyanika njira makamaka maburashi madzi zopangira pamwamba pa graphite masanjidwewo, ndiyeno solidifies zopangira pa kutentha kwina kukonzekera ❖ kuyanika. Njirayi ndi yosavuta komanso yotsika mtengo, koma zokutira zomwe zimakonzedwa ndi njira yopangira burashi zimakhala ndi chomangira chofooka ndi matrix, kusafanana kwapadera, kuyanika kochepa komanso kutsika kwa okosijeni, ndipo kumafuna njira zina zothandizira.

Njira yopopera plasma
Kupopera mbewu mankhwalawa kwa plasma makamaka amagwiritsa ntchito mfuti ya plasma kupopera mankhwala osungunuka kapena theka-wosungunuka pamwamba pa gawo lapansi la graphite, ndiyeno amalimba ndi zomangira kuti apange zokutira. Njira imeneyi ndi yosavuta kugwiritsa ntchito ndipo akhoza kukonzekera ndi wandiweyanizokutira za silicon carbide, komazokutira za silicon carbidezokonzedwa ndi njira imeneyi nthawi zambiri wofooka kwambiri kuti kukana makutidwe ndi okosijeni amphamvu, choncho amagwiritsidwa ntchito pokonzekera zokutira gulu SiC kusintha khalidwe ❖ kuyanika.

Gel-sol njira
Njira ya gel-sol makamaka imakonzekeretsa yunifolomu komanso yowoneka bwino yothetsera sol kuti iphimbe pamwamba pa gawo lapansi, imawumitsa mu gel, ndiyeno imayimitsa kuti ipeze zokutira. Njirayi ndi yosavuta kugwiritsa ntchito ndipo imakhala ndi mtengo wotsika, koma chophimba chokonzekera chimakhala ndi zovuta monga kutsika kwa kutentha kwa kutentha ndi kuphulika kosavuta, ndipo sikungagwiritsidwe ntchito kwambiri.

Chemical vapor reaction method (CVR)
CVR makamaka imapanga mpweya wa SiO pogwiritsa ntchito Si ndi SiO2 ufa pa kutentha kwakukulu, ndipo mndandanda wa zochita za mankhwala zimachitika pamwamba pa gawo lapansi la C kuti apange zokutira za SiC. Chophimba cha SiC chokonzedwa ndi njirayi chimamangirizidwa mwamphamvu ku gawo lapansi, koma kutentha kwazomwe kumakhala kwakukulu komanso mtengo wake ndi wokwera.
