Iko kushandiswa kwakapararira kwetitanium alloys muminda yekugadzira maindasitiri nekuda kweiyo yakasarudzika yakakwirira-huremu reshiyo, kuramba kwekutyoka, uye nepamusoro kuramba kukorona.Nhamba inowedzera yemakambani inosarudza kushandisa Titanium alloy TC11 pachinzvimbo cheTC4 mukugadzira impellers uye mashizha, nekuda kweiyo iri nani yekupisa kuramba pfuma uye kugona kushanda mukupisa kwakanyanya kwenguva yakareba.Titanium alloys ndeye classical yakaoma-kune-muchina zvinhu kune yavo yekuzvarwa simba repamusoro rakachengetwa pakakwirira tembiricha uye yakaderera yekupisa conductivity inotungamira kune yakanyanya kucheka tembiricha.Kune zvimwe zvikamu zveaero-injini, senge ma impellers, ane nzvimbo dzakamonyoroka, zvakaoma kugutsa iyo yepamusoro uye yepamusoro yepamusoro yemhando zvinodiwa nekungoshandisa kugaya.
Mune injini yemoto mukati memoto, turbocharger rotor yakabatsira pakuwedzera kwezvose zviri zviviri kushanda kwesimba uye kuderedza mafuta, nokuti gasi rinopisa rinokurudzira kushanda zvakanaka pasina kuwedzera kushandiswa kwemafuta.Zvakadaro, rota yeturbocharger ine dambudziko rinouraya rinodaidzwa kuti ''turbo-lag'' rinononotsa kushanda kwakadzikama kweturbocharger pasi pe2000 rpm.Titanium aluminides inogona kuderedza huremu kusvika pahafu yeyakajairika turbocharger.Kunze kwezvo, maTiAl alloys ane musanganiswa weiyo yakaderera density, yakakwira chaiyo simba, yakanakisa michina zvivakwa, uye kupisa kuramba.Saizvozvo, TiAl alloys anogona kubvisa iyo turbo-lag dambudziko.Kusvika ikozvino, yekugadzira turbocharger, poda metallurgy uye casting process yakabatanidzwa.Nekudaro, zvakaoma kushandisa poda metallurgy process kune turbocharger kugadzira, nekuda kwekushata kwayo kunzwika uye weldability.
Kubva pamaonero ekuita zvinodhura, kukanda mari kunogona kutariswa sehupfumi net-shape tekinoroji yeTiAl alloys.Nekudaro, iyo turbocharger ine zvese curvature uye yakatetepa madziro zvikamu, uye hapana ruzivo rwakakodzera senge castability uye fluidity ine mold tembiricha, kunyunguduka tembiricha uye centrifugal simba.Iyo modhi yekukanda inopa ine simba uye inodhura-inoshanda nzira yekudzidza kushanda kweakasiyana ekukanda paramita.
