I-SiC/SiCinokumelana okuhle kakhulu nokushisa futhi izothatha indawo ye-superalloy ekusetshenzisweni kwenjini ye-aero
Isilinganiso esiphezulu sokusunduza isisindo siwumgomo wezinjini ze-aero ezithuthukisiwe. Kodwa-ke, ngokwanda kwesilinganiso sokusunduza isisindo, izinga lokushisa lokungena kwe-turbine liyaqhubeka nokukhula, futhi uhlelo lwezinto ze-superalloy olukhona kunzima ukuhlangabezana nezidingo zezinjini ze-aero ezithuthukisiwe. Isibonelo, izinga lokushisa lokungena kwe-turbine lezinjini ezikhona ezinesilinganiso sokusunduza isisindo sezinga le-10 selifinyelele ku-1500℃, kuyilapho izinga lokushisa elimaphakathi lokungena kwezinjini ezinesilinganiso sokusunduza isisindo se-12~15 lizodlula ku-1800℃, okungaphezu kakhulu kwezinga lokushisa lesevisi lama-superalloy nama-intermetallic compounds.
Njengamanje, i-superalloy esekelwe ku-nickel enokumelana nokushisa okungcono kakhulu ingafinyelela cishe ku-1100℃. Izinga lokushisa lesevisi le-SiC/SiC lingakhushulwa libe ngu-1650℃, okubhekwa njengento efanelekile kakhulu yokwakha i-aero-injini.
EYurophu nase-United States nakwamanye amazwe athuthukile ezindiza,I-SiC/SiCKuye kwaba ukusetshenziswa okusebenzayo kanye nokukhiqizwa okukhulu ezingxenyeni ezimile ze-aero-engine, okuhlanganisa i-M53-2, i-M88, i-M88-2, i-F100, i-F119, i-EJ200, i-F414, i-F110, i-F136 kanye nezinye izinhlobo zezinjini ze-aero zempi/zomphakathi; Ukusetshenziswa kwezingxenye ezijikelezayo kusesesigabeni sokuthuthukiswa nokuhlolwa. Ucwaningo oluyisisekelo eShayina lwaqala kancane, futhi kukhona igebe elikhulu phakathi kwalo nocwaningo olusetshenziswa ngobunjiniyela emazweni angaphandle, kodwa futhi lwenze impumelelo.
NgoJanuwari 2022, uhlobo olusha lwe-ceramic matrix composite luqalwa yi-Northwest Polytechnical University esebenzisa izinto zasekhaya ukwakha i-turbine disc yenjini yendiza eqeda ngempumelelo ukuhlolwa kokuqala kokundiza, futhi kungokokuqala ngqa i-ceramic matrix composite rotor yasekhaya efakwe ipulatifomu yokuhlola indiza yomoya, kodwa futhi nokukhuthaza izingxenye ze-ceramic matrix composites emotweni yendiza engenamuntu (uav)/drone enkulu.
