Iindawo zokusetyenziswa zeSiC/SiC

I-SiC/SiCinokumelana nobushushu okugqwesileyo kwaye iya kuthatha indawo ye-superalloy ekusebenziseni i-aero-injini

Injongo yeenjini ze-aero eziphucukileyo kukuba umlinganiselo ophezulu wokutyhala ukuya kobunzima uyanda. Nangona kunjalo, ngokwanda komlinganiselo wokutyhala ukuya kobunzima, ubushushu bokungena kwe-turbine buyaqhubeka nokwanda, kwaye inkqubo yezinto ze-superalloy ezikhoyo kunzima ukuhlangabezana neemfuno zeenjini ze-aero eziphucukileyo. Umzekelo, ubushushu bokungena kwe-turbine kwiinjini ezikhoyo ezinomlinganiselo wokutyhala ukuya kobunzima wenqanaba le-10 bufikelele kwi-1500℃, ngelixa ubushushu obuqhelekileyo bokungena kweenjini ezinomlinganiselo wokutyhala ukuya kobunzima we-12~15 buya kudlula kwi-1800℃, okungaphezulu kakhulu kobushushu benkonzo yee-superalloys kunye nee-intermetallic compounds.

Okwangoku, i-superalloy esekelwe kwi-nickel enokumelana nobushushu obuphezulu inokufikelela kuphela kwi-1100℃. Ubushushu benkonzo ye-SiC/SiC bunokwandiswa bube yi-1650℃, nto leyo ethathwa njengeyona nto ifanelekileyo yokwakha i-hot end structure ye-aero-injini.

EYurophu naseMelika nakwamanye amazwe aphuhlileyo eenqwelo-moya,I-SiC/SiCiye yasetyenziswa ngokubonakalayo kwaye yaveliswa ngobuninzi kwiindawo ezisisigxina zeenjini ze-aero, kuquka i-M53-2, i-M88, i-M88-2, i-F100, i-F119, i-EJ200, i-F414, i-F110, i-F136 kunye nezinye iintlobo zeenjini ze-aero zomkhosi/zoluntu; Ukusetyenziswa kweendawo ezijikelezayo kusesekwinqanaba lophuhliso novavanyo. Uphando olusisiseko eTshayina luqale kancinci, kwaye kukho umsantsa omkhulu phakathi kwayo nophando olusetyenziswa ngobunjineli kumazwe angaphandle, kodwa lukwaphumelele.

NgoJanuwari 2022, uhlobo olutsha lwe-ceramic matrix composite luza kusetyenziswa yiyunivesithi yaseNorthwest polytechnical esebenzisa izixhobo zasekhaya ukwakha idiski ye-turbine yenjini yeenqwelo moya ukugqitywa ngempumelelo kovavanyo lokuqala lokubhabha, ikwalixesha lokuqala i-ceramic matrix composite rotor yasekhaya exhotyiswe ngeqonga lovavanyo lokubhabha emoyeni, kodwa ikwakhuthaza izixhobo ze-ceramic matrix composites kwisithuthi somoya esingenamntu (uav)/drone esisetyenziswa kakhulu.
