Kodi zosefera za ceramic thovu ndi ziti?

Zida zoyambira zosefera thovu za ceramic ndizosilicon carbide, zirconium oxide ndi alumina
Fyuluta ya thovu ya ceramic imakhala ndi kusefera kwamadzi amkuwa kapena chitsulo, kutengera mawonekedwe amitundu itatu, kuchotsa bwino zosakaniza zokhala ndi okosijeni ndi zosakaniza zina zopanda zitsulo, kutsekereza kugwidwa ndi kutsatsa. Kaya ndi imvi chitsulo, chitsulo ductile kapena kutsinde, silinda kapena zigawo zikuluzikulu zovuta, mwatsatanetsatane kuponya mbali zosefedwa, khalidwe mankhwala adzakhala zotsatira zokhutiritsa.
Zosefera thovu za ceramicndizoyeneranso mkuwa, mkuwa, mkuwa ndi ma aloyi ena amkuwa, kuchepetsa chipwirikiti chamadzimadzi amkuwa ndikuwongolera ndi kuyeretsa chitsulo chosungunuka. Chofunika kwambiri ndikuwonjezera kwakukulu kwa moyo wautumiki wazitsulo zamkuwa m'malo ovuta kwambiri kapena ovuta kwambiri monga ma turbine a sitima zapamadzi, zigawo za mankhwala, ndi zina zotero. Zimakhalanso ndi zotsatira zabwino pazitsulo zamkuwa zokhala ndi zofunikira zopukuta pamwamba. Zosefera za foam ceramic zimagwiranso ntchito yofunika kwambiri pakupanga mkuwa wachikhalidwe, kupanga mkuwa wamagetsi ndi njira zopitilirabe zoponya ndikugudubuza. Chifukwa cha kuchuluka kwa mkuwa ndi ma aloyi, kuphatikiza ma aloyi a zinki, omwe amatulutsa kugwedezeka kwakukulu panthawi yoponya, kugwiritsa ntchito silicon carbide thovu kuphatikiza zosefera za ceramic nthawi zambiri zimatsatiridwa ndi malamulo okhwima pakukula kwake.
Zakuthupi
Zofunikira pazosefera za ceramic ndi oxidized clean Zr02.zosefera zirconiaali ndi kutentha kosagwira kutentha kuposa 1760 ° C, mphamvu zambiri komanso kutentha kwapamwamba.
Zigawo zachitsulo zotayidwa zimagwiritsidwa ntchito kwambiri pomwe mphamvu yayikulu ndi elongation imafunikira. Chifukwa chake, zida zachitsulo zotayidwa zimakhudzidwa kwambiri ndi zonyansa-zimapangitsa kuti zizikhala zazifupi, ndipo mawonekedwe abwino kwambiri a zosefera za thovu ceramic amatha kuchotsa zonyansa zomwe pamapeto pake zimabweretsa kutsika kwachidule. Zonyansa makamaka amapangidwa sanali zitsulo particles, slag ndi refractory zinyalala, amene bwino pamwamba khalidwe ndi mawotchi katundu castings ndi kuchepetsa zinyalala mlingo.
Fyuluta ya thovu ya Ceramic imatha kupanga chitsulo chamadzimadzi kudzaza pabowo molingana, ndipo chitsulo chosungunuka chimakhala ndi chizolowezi chachikulu cha chipwirikiti pakutsanulira. The atatu azithunzithunzi pore kapangidwe kazosefera thovu za ceramicchipwirikiti otaya potsirizira pake kusandulika khola kwambiri laminar otaya. Kuthamanga kwa laminar kumadzaza bwino patsekeke, motero kuchepetsa kuwonongeka kwazitsulo zachitsulo pazitsulo zoponyera komanso kuchepetsa kwambiri zinyalala.
