I-Inconel 718 Alloy: I-Performance King in High{1}}End Industrial Sectors

Njengemvula-i-nickel eqinile-i-chromium{2}}i-iron alloy, i-Inconel 718 isiphenduke into ebalulekile emikhakheni{4}}ephezulu yezimboni efana ne-aerospace, amandla, nobunjiniyela basolwandle, ngenxa yamandla ayo aphezulu{5}}okushisa okuphezulu, ukumelana nokunwabuleka, nokugqwala. Isekela kakhulu ukusebenza kwemishini eyinhloko ngaphansi kwezindawo eziyingozi kakhulu.

Emkhakheni we-aerospace, i-Inconel 718 isebenza "njengohlaka oluyisisekelo" lwezinjini nemikhumbi-mkhathi. Isetshenziselwa ukwenza izingxenye ezinjengamadiski ophephela, ama-blades, namakamelo avuthayo ezinjini ze-aero-ezikwazi ukusebenza ngokuzinzile{3}}emazingeni okushisa aphezulu (650{5}}700℃) kanye nezindawo ezinengcindezi ephezulu. Ngaleso sikhathi, ama-turbopump enjini yerokhethi, amafreyimu esakhiwo semikhumbi-mkhathi, nezinye izingxenye nazo zithembele ekhonweni layo lokumelana nokwehluka kwezinga lokushisa elidlulele kanye nokucindezela okuphezulu.

Ingxubevange ibaluleke ngokulinganayo emkhakheni wezamandla. Izingxenye eziphezulu-zezinga lokushisa eziphakeme zezinjini zegesi, imikhumbi yokucindezela nezishintshisi zokushisa kumareactor enyukliya, kanye namavalvu okuphepha e-downhole okukhipha uwoyela{2}}olwandle ojulile, konke kukhuthaza ukumelana kwawo{3}}nokugqwala okuphezulu kwezinga lokushisa, emisebeni, kanye nokucindezela okuphezulu ukuze kuqinisekiswe ukukhiqizwa kwamandla okuphumelelayo nokuphephile.

Kubunjiniyela basolwandle, inzuzo ye-Inconel 718 ekumelaneni nokugqwala kwamanzi olwandle igqamile. Isetshenziswa kakhulu ezingxenyeni zesakhiwo seplatifomu engasogwini, amapayipi angaphansi kolwandle, namathuluzi okukhipha usawoti emanzini olwandle, amelana ngempumelelo{{2}nokuguguleka kwesikhathi eside ezindaweni zasolwandle.

Ukwengeza, ekukhiqizweni kwemishini{0}ephezulu ephezulu, ingatholakala ezingxenyeni ezinembayo ezifana-nezinga lokushisa eliphezulu{2}}isikhunta esisakazayo kanye{3}}nezixhumi ze-compressor ezinesivinini esiphezulu. Ngisho nakumadivaysi ezokwelapha (isb., amathuluzi okuhlinza inhliziyo) kanye nezingxenye ezibalulekile{7}}zezinjini zezimoto ezisebenza kahle, ibambe isikhundla esibalulekile ngenxa yokuvumelana kwayo kwezinto eziphilayo kanye nokuvumelana nezimo zokusebenza ngokweqile.

Kusuka esibhakabhakeni kuye ekujuleni kolwandle, kusukela kuma-energy cores kuya kumishini yezokwelapha enembayo, i-Inconel 718 ivela "njengetshe legumbi elingabonakali" eliqhuba ukuthuthukiswa-kwezimboni eziphezulu{2}}ngokusebenza kwayo okuhle kakhulu.
