Impumelelo enkulu embonini ye-aerospace ihlukaniswa kusuka ekuthuthukisweni nasekuphumeleleni kubuchwepheshe bezinto ezibonakalayo ze-aerospace. Ukuphakama okuphezulu, isivinini esikhulu kanye ne-maneuverability ephezulu yama-fighter jets adinga ukuthi izinto zokwakha izindiza kufanele ziqinisekise amandla anele kanye nezidingo zokuqina. Izinto zokwenziwa kwenjini zidinga ukufeza isidingo sokumelana okuphezulu okushisa, amazinga okushisa aphezulu, izinto zezinhlanganisela ezenziwa yi-ceramic ezisekelwe ezintweni ezibalulekile.
Insimbi evamile ithambisa ngaphezulu kwama-300 ℃, okwenza kungakulungele izindawo zokushisa okuphezulu. Ekuphishekeleni ukusebenza kahle kwamandla okuguqulwa kwamandla, amazinga okushisa aphezulu naphezulu adingekayo emkhakheni wamandla enjini yokushisa. Ama-alloys angashisa aphezulu athuthukiselwe ukusebenza okuzinzile emazingeni okushisa angenhla kwama-600 ℃, futhi ubuchwepheshe buyaqhubeka nokuvela.
Ama-alloys angaphezulu aphezulu yizinto ezisemqoka zezinjini ze-aerospace, ezihlukaniswe ngama-alloys aphansi asuselwa ku-air-based, ama-nickel-asuselwa ezintweni eziphambili ze-alloy. Ama-alloys angaphezulu asetshenzisiwe e-aero-izinjini selokhu asungulwa, futhi ayizinto ezibalulekile ekwenziweni kwezinjini ze-aerospace. Izinga lokusebenza lenjini lincike kakhulu ezingeni lokusebenza kwezinga lokushisa eliphakeme le-alloy. Kwezinjini zesimanje ze-AERO-, inani lezinto ezishitshuzayo ze-Alloy eziphakeme ze-ALTOY zamaphesenti angama-40-60 amaphesenti wesisindo esiphelele senjini, futhi asetshenziselwa ama-turbine ama-disc kanye nama-turbine ama-disc, futhi ngokungeziwe, asetshenziselwa ama-computer anjengomagazini kanye nama-nozzles omsila.
(Ingxenye ebomvu yomdwebo ikhombisa ama-alloys aphezulu)
Ama-alloys asuselwa ku-nickel aphansi Ngokuvamile zisebenza ngo-600 ℃ ngenhla kwezimo zengcindezi ethile, akugcini nje ngokuba ne-oxidation ephezulu yokushisa nokuphikiswa, futhi inamandla okushisa aphezulu, amandla okushisa aphezulu, amandla okukhuthazela, kanye nokuphikiswa okuhle kokukhathala. Isetshenziswa ikakhulukazi emkhakheni we-aerospace kanye nendiza ngaphansi kwezimo zokushisa okuphezulu, izakhi zezakhiwo, ezinjengezinjini zezindiza, ama-turbine disc, amakamelo okuhlangana nokunye. Ama-alloys aphansi asuselwa ku-nickel angahlukaniswa abe ama-alloys angashintshiwe aphezulu, aphonsa ama-alloys aphezulu okushisa kanye nama-alloys amasha aphezulu ngokwenqubo yokukhiqiza.
Ngokushisa okusebenzayo okuvinjelwe ukushisa kuphakeme futhi kuphakeme, izinto eziqinisa i-alloy ziningi ngokwengeziwe, okuyinkimbinkimbi ngokwengeziwe ukwakheka, okuholela kwamanye ama-alloys kungasetshenziswa kuphela ku-Cast State. Ngaphezu kwalokho, ukwanda kwezinto ezenziwa ngezabelo kwenza ama-alloys asuselwa ku-nickel aqiniswe ngokuhlukaniswa okubucayi kwezakhi, okuholela ekungathathilini kwenhlangano nezakhiwo.Ukusetshenziswa kwenqubo ye-powder metallurgy ukukhiqiza ama-alloys aphezulu okushisa, angaxazulula izinkinga ezingenhla.Ngenxa yezinhlayiya ezincane ze-powder, isivinini sokupholisa i-powder, ukuqeda ukuhlukaniswa, ukukhiqizwa okushisayo okuthuthukile, i-alloy yoqobo yokudla ibe wukuvuselelwa okushisayo kwama-alloys aphezulu ashisekayo, amandla okushisa aphezulu okukhiqizwayo kwama-alloys anamandla aphezulu akhiqize indlela entsha.
