SiC/SiCwaxay leedahay iska caabin kulayl aad u fiican waxayna bedeli doontaa superalloy codsiga aero-engine
Saamiga culeyska-sare ee culeyska waa yoolka matoorada-matoorada horumarsan. Si kastaba ha ahaatee, korodhka culeyska culeyska culeyska, heerkulka gelitaanka marawaxadaha ayaa sii kordhaya, iyo nidaamka walxaha superalloy ee jira way adag tahay in la buuxiyo shuruudaha matoorada-mashiinnada sare. Tusaale ahaan, heerkulka daloolka marawaxadaha ee matoorada jira ee leh culeyska culeyska ee heerka 10 ayaa gaaray 1500 ℃, halka celceliska heerkulka gudaha ee matoorada leh saamiga culeyska-miisaanka ee 12 ~ 15 uu dhaafi doono 1800 ℃, taas oo aad uga fog heerkulka adeegga ee superalloys iyo isku dhafka dhexdhexaadka ah.
Waqtigan xaadirka ah, superalloy-ku-saleysan nikkel oo leh iska caabbinta kulaylka ugu fiican waxay gaari kartaa oo keliya 1100 ℃. Heerkulka adeegga ee SiC/SiC waa la kordhin karaa ilaa 1650 ℃, kaas oo loo arko inuu yahay midka ugu habboon ee hawo-matoorka qaab dhismeedka kuleylka kuleylka ah.
Yurub iyo Maraykanka iyo dalalka kale ee hore u maray duulista.SiC/SiCwuxuu ahaa codsi wax ku ool ah iyo wax soo saarka ballaaran ee qaybaha aero-engine-ga, oo ay ku jiraan M53-2, M88, M88-2, F100, F119, EJ200, F414, F110, F136 iyo noocyada kale ee militariga / matoorada aero-madaniga ah; Codsiga qaybaha wareega ayaa weli ku jira marxaladda horumarinta iyo imtixaanka. Cilmi-baarista aasaasiga ah ee Shiinaha ayaa si tartiib tartiib ah u bilaabatay, waxaana jira farqi weyn oo u dhexeeya iyada iyo injineernimada cilmi-baarista ee dalalka shisheeye, laakiin sidoo kale waxay samaysay guulo.
Janaayo 2022, nooc cusub oo ah matrix dhoobo ah ayaa ah jaamacada farsamada gacanta ee waqooyi-galbeed iyadoo la adeegsanayo agab gudaha ah si ay u dhisto mishiinka marawaxadaha hawada ee hawada si guul ah u dhammaystiray imtixaankii duulimaadkii ugu horeeyay, sidoo kale waa markii ugu horaysay ee rotor-ka dhoobada dhoobada ah ee gudaha oo ku qalabaysan madal tijaabada duulimaadka hawada, laakiin sidoo kale si kor loogu qaado qalabka dhoobada dhoobada ah ee ka kooban qaybaha gaadhiga aan la wadin.
