SiC/SiCili ndi kukana kwambiri kutentha ndipo idzalowa m'malo mwa superalloy pakugwiritsa ntchito injini ya aero
Chiyerekezo chokwera kwambiri cha thrust-to-weight ndicho cholinga cha ma aero-injini apamwamba. Komabe, pakuwonjezeka kwa chiŵerengero cha thrust-to-weight, kutentha kwa turbine inlet kukupitirirabe, ndipo makina omwe alipo a superalloy ndi ovuta kukwaniritsa zofunikira zamainjini apamwamba. Mwachitsanzo, kutentha kwa injini ya turbine ya injini yomwe ilipo yokhala ndi chiŵerengero cha 10-kulemera kwa mlingo wa 10 kufika pa 1500 ℃, pamene kutentha kwapakati kwa injini zomwe zimakhala ndi chiŵerengero cha 12 ~ 15 zidzapitirira 1800 ℃. kupitirira kutentha kwa utumiki wa superalloys ndi intermetallic mankhwala.
Pakali pano, faifi yochokera ku superalloy yokhala ndi kutentha kwabwino kwambiri imatha kufika pafupifupi 1100 ℃. Kutentha kwautumiki wa SiC/SiC kumatha kuonjezedwa mpaka 1650 ℃, komwe kumawonedwa ngati chinthu choyenera kwambiri cha injini ya aero-injini yotentha kwambiri.
Ku Europe ndi United States ndi mayiko ena otukuka oyendetsa ndege,SiC/SiCyakhala ikugwiritsidwa ntchito komanso kupanga misa m'malo oyimilira aero-injini, kuphatikiza M53-2, M88, M88-2, F100, F119, EJ200, F414, F110, F136 ndi mitundu ina yamainjini ankhondo / wamba; Kugwiritsa ntchito magawo ozungulira akadali pagawo lachitukuko ndi mayeso. Kafukufuku woyambira ku China adayamba pang'onopang'ono, ndipo pali kusiyana kwakukulu pakati pake ndi uinjiniya adagwiritsa ntchito kafukufuku kumayiko akunja, koma wapindulanso.
Mu January 2022, mtundu watsopano wa ceramic masanjidwewo gulu ndi kumpoto chakumadzulo polytechnical yunivesite ntchito zipangizo zapakhomo kumanga ndege injini chopangira turbine chimbale zonse bwino kumaliza mayeso ndege yoyamba, ndi nthawi yoyamba m'banja ceramic masanjidwewo gulu rotor okonzeka ndi ndege ndege. nsanja yoyesera, komanso kulimbikitsa zida za ceramic matrix composites pagalimoto yosayendetsedwa ndi ndege (uav)/drone ntchito yayikulu.
