Ma Alloys Otentha Kwambiri - Mphamvu Yopanga Zatsopano M'malo Ovuta Kwambiri

Kutentha kwambiri Aloyis, gulu la zipangizo zachitsulo zapamwamba, zikufunidwa nthawi zonse chifukwa cha ntchito yawo yofunika kwambiri mu ndege, kupanga magetsi, ndi mafakitale ena apamwamba.AloyiMa s amapangidwa kuti akhale ndi mphamvu zapadera zamakanika, asamawonongeke pamwamba, komanso azikhala olimba akamavutika kwambiri kutentha kopitilira 1000°F (540°C), nthawi zambiri mpaka 85% ya malo awo osungunuka.

Kuphatikiza kwawo kosayerekezeka kwa zinthu zofunika kwambiri—kuphatikizapo kukana kukwawa bwino, kupirira kukhuthala ndi dzimbiri, komanso kupirira kutopa kwa kutentha—kumapangitsa kuti zikhale zofunika kwambiri. Kuchita bwino kumeneku kumachokera ku zinthu zovuta, zomwe nthawi zambiri zimachokera ku nickel, cobalt, kapena chitsulo, ndipo zimawonjezeredwa ndi zinthu monga chromium, aluminiyamu, ndi zitsulo zotsutsa.

Mapulogalamu​ makamaka m'magawo omwe kulephera si njira yabwino. Makampani opanga ndege​ndiye ogula ambiri, pogwiritsa ntchito izi AloyiKupanga mphamvu mu masamba a turbine, ma disc, ndi zipinda zoyatsira moto zama injini a jet ndi ma turbine okhala pamtunda.​ Gawoli limadalira pa iwo pa magawo otentha kwambiri a ma turbine a gasi m'mafakitale amagetsi amakono komanso atsopano, ogwira ntchito bwino. Ntchito zazikulu zimafikiranso pa kukonza mankhwala, ma turbocharger a magalimoto, ndi minda yatsopano monga rocket propulsion​ ndi ma reactor apamwamba a nyukiliya.

Kiyi Aloyi mabanja ndipo ntchito zawo zazikulu zikuphatikizapo:

Yopangidwa ndi nikeli Aloyis (monga Inconel 718, Rene N5): Banja lomwe limagwiritsidwa ntchito kwambiri. Inconel 718 ndi gulu logwira ntchito kwambiri la ma disk a turbine ya gasi, zomangira, ndi zida zomangira mumlengalenga. Rene N5 ndi ma crystal amodzi ofanana a m'badwo wachitatu. AloyiMa s amagwiritsidwa ntchito kokha pa ntchito zovuta kwambiri: masamba a turbine m'mainjini a ndege zamalonda ndi zankhondo.

Yochokera ku Cobalt Aloyis (monga Haynes 188, Stellite 6): Amadziwika bwino chifukwa cha kukana dzimbiri kutentha komanso magwiridwe antchito ake osatha. Amagwiritsidwa ntchito m'ma vane osasuntha, ma fire liners, komanso pogwiritsira ntchito ma turbines olimba, komanso m'ma implants azachipatala.

Yopangidwa ndi chitsulo cha nikeli Aloyis (monga A-286, Incoloy 800H): Amadziwika ndi mphamvu zabwino komanso mtengo wotsika. Amagwiritsidwa ntchito kwambiri m'mawilo a turbocharger, makina otulutsa utsi, ndi zida zomangira ndege, komanso zosinthira kutentha pokonza mankhwala.

Msika wapadziko lonse lapansi​kutentha kwambiri Aloyis ikadali yolimba koma imakhudzidwa kwambiri ndi mtengo wa zinthu zopangira komanso momwe zinthu zimayendera. Mitengo ya zinthu zofunika monga nickel, cobalt, ndi tantalum imakhudza mwachindunji Aloyi Mitengo. Malinga ndi akatswiri amakampani, msika ukuyembekezeka kukula pang'onopang'ono pamlingo wokulirapo pachaka (CAGR) wa pafupifupi 5-7%, womwe ungafikire mtengo wa madola mabiliyoni ambiri pofika kumapeto kwa zaka khumi. Kukula kumeneku kukuthandizidwa ndi kuwonjezeka kwa kupanga ndege zamalonda, kufunikira kwa magetsi ogwira ntchito bwino, ndi mapulogalamu amakono ankhondo padziko lonse lapansi. Pakadali pano, msikawu uli ndi makampani akuluakulu apadera azitsulo ndi opanga zinthu zina, pomwe North America ndi Europe zili ndi makampani opanga zinthu zambiri komanso ukadaulo, ngakhale Asia-Pacific ndi kampani yomwe ikukula mwachangu ndi ogula komanso opanga zinthu zatsopano.

Poyang'ana patsogolo, luso lamakono limayang'ana kwambiri pakukula Aloyindi mphamvu zotentha kwambiri komanso kukana chilengedwe kwa injini za m'badwo wotsatira, pamodzi ndi njira zamakono zopangira monga kusindikiza kwa 3D kuti muchepetse ndalama ndi kuwononga zinthu. Pamene mafakitale akukankhira malire a magwiridwe antchito ndi magwiridwe antchito, kutentha kwambiri Aloyis ipitiliza kukhala ukadaulo woyambira kupita patsogolo.
