Kukusetyenziswa ngokubanzi kweealloyi ze-titanium kwiinkalo zemveliso yemizi-mveliso ngenxa yomlinganiselo wazo okhethekileyo wamandla obunzima, ukunganyangeki kokwaphuka, kunye nokuxhathisa okuphezulu ekudlekeni.Inani elikhulayo leenkampani likhetha ukusebenzisa i-Titanium alloy TC11 endaweni ye-TC4 ekuveliseni i-impellers kunye ne-blades, ngenxa yepropati yokumelana nokutsha kunye nokukwazi ukusebenza kwiqondo lokushisa eliphezulu ixesha elide.Iialloyi ze-Titanium zizinto zakudala ezinzima kumatshini kumandla azo aphezulu agcinwe kubushushu obuphakamileyo kunye nokuhanjiswa kwe-thermal ephantsi ekhokelela kumaqondo obushushu aphezulu.Kwamanye amacandelo e-injini ye-aero, enjenge-impellers, enemigangatho ejijekileyo, kunzima ukwanelisa iimfuno zomgangatho ophezulu kunye nophezulu womphezulu ngokusebenzisa nje umsebenzi wokusila.
Kwi-injini yokutshisa yangaphakathi yeemoto, i-rotor ye-turbocharger ibe negalelo ekunyuseni kokubini amandla ombane kunye nokunciphisa i-fuel, kuba i-gas yokukhupha i-gas ikhuthaza ukusebenza kakuhle ngaphandle kokusetyenziswa kwamafutha okongeziweyo.Nangona kunjalo, i-rotor ye-turbocharger ine-drawback ebulalayo ebizwa ngokuba yi-''turbo-lag'' elibazisa ukusebenza okuzinzileyo kwe-turbocharger phantsi kwe-2000 rpm.I-Titanium aluminides inokunciphisa ubunzima kwisiqingatha se-turbocharger eqhelekileyo.Ngaphandle koko, ii-alloys ze-TiAl zinendibaniselwano yoxinzelelo oluphantsi, amandla athile aphezulu, iipropathi ezigqwesileyo zoomatshini, kunye nokumelana nobushushu.Ngokufanelekileyo, iialloys zeTiAl zinokuphelisa ingxaki ye-turbo-lag.Ukuza kuthi ga ngoku, ukwenza i-turbocharger, umgubo wesinyithi kunye nenkqubo yokuphosa zibandakanyiwe.Nangona kunjalo, kunzima ukufaka inkqubo yesinyithi somgubo kwimveliso ye-turbocharger, ngenxa yesandi sayo esibi kunye nokushisela.
Ngokwembono yenkqubo eyonga imali, ukufakwa kotyalo-mali kunokuthathwa njengobuchwephesha bobume boqoqosho kwiialloyi ze-TiAl.Nangona kunjalo, i-turbocharger inazo zombini i-curvature kunye neendawo ezibhityileyo zodonga, kwaye akukho lwazi lufanelekileyo olufana nokuphosa kunye nokumanzi kunye nobushushu bokubumba, ubushushu obunyibilikayo kunye namandla e-centrifugal.Imodeli yokuphosa inika indlela enamandla kunye neendleko ezifanelekileyo zokufunda ukusebenza kweeparitha ezahlukeneyo zokuphosa.
