Indasteri ea sepakapaka e hloka thepa e ka mamellang maemo a feteletseng—mocheso o matla, khatello le tikoloho e senyang. Li-alloys tsa Nickel li hlahile e le lisebelisoa tsa bohlokoa lefapheng lena, tse fanang ka ts'ebetso e phahameng ka ho fetisisa mefuteng e mengata ea likopo tsa bohlokoa. Sengoliloeng sena se shebisisa bohlokoa ba li-alloys tse sa tloaelehang tsa nickel bakeng sa sepakapaka mme se hlalosa hore na ke hobaneng li le bohlokoa molemong oa tsoelopele le polokeho ea indasteri.
Karolo ea Of Nickel Alloyssebakeng sa Aerospace
Boenjiniere ba lifofane bo sutumelletsa meeli ea saense ea lintho tse bonahalang, e hlokang likarolo tse lulang li tsitsitse tlas'a maemo a phahameng a khatello ea kelello. Li-alloys tse sa tloaelehang tsa nickel bakeng sa sefofane li fetohile karolo ea bohlokoa ea indasteri ka lebaka la thepa ea tsona e ikhethang. Li-alloys tsena li etselitsoe ho sebetsa libakeng tseo mocheso o feteletseng, oxidation le corrosion li atileng teng.
Ka mohlala, lienjineng tsa lifofane, li-alloys tsa nickel li sebelisoa li-blades tsa turbine, li-discs, le likarolo tse ling tsa mocheso o phahameng ka lebaka la bokhoni ba tsona ba ho boloka matla a mochine le ho hanyetsa oxidation mochesong o ka holimo ho 1,000 ° C. Ho hanyetsa mocheso hona ho bohlokoa, kaha lienjene tsa jete le li turbine li sebetsa tlas'a maemo a matla, 'me ho hlōleha leha e le hofe ho ka ba le liphello tse kotsi.
Ho hanyetsa Corrosion: Molemo o Moholo
Corrosion ke taba ea bohlokoa boenjiniere ba lifofane. Hangata lifofane li kopana le maemo a sa tšoaneng a sepakapaka, ho akarelletsa le ho pepesehela mongobo, metsi a letsoai le lintho tse ling tse senyang. Li-alloys tsa Nickel li fana ka khanyetso e phahameng ea kutu, e li etsa hore e be tse phethahetseng bakeng sa likarolo tse lokelang ho mamella maemo a thata. Thepa ena e lelefatsa bophelo ba likarolo tsa sefofane, ho fokotsa litšenyehelo tsa tlhokomelo le ho eketsa ts'epo ea ts'ebetso.
Ka mohlala, li-alloys tsa nickel li sebelisoa mecheng ea ho ntša metsi, li-fasteners le lithapo tsa mafura ka lebaka la tlhaho ea tsona e sa bolaeeng ke kutu. Ho sebelisa li-alloys tsa nickel tse sa tloaelehang bakeng sa sefofane libakeng tsena ho netefatsa hore sefofane se ka sebetsa ka mokhoa o sireletsehileng libakeng tse fapaneng, ho tloha ho tšela maoatle ho ea ho lifofane tse phahameng.
Karolelano e Phahameng ea Matla le Boima
Karo-karolelano ea matla ho boima ba 'mele ke ntlha e' ngoe ea bohlokoa boenjiniere ba lifofane. Lisebelisoa li hloka ho ba matla ka ho lekana ho mamella matla a mochini ha li ntse li le bobebe ho ntlafatsa ts'ebetso ea mafura. Li-alloys tsa nickel li otla tekanyo ena hantle, li fana ka matla a babatsehang ntle le ho eketsa boima bo sa hlokahaleng. Sena se etsa hore li tšoanelehe bakeng sa likarolo tse peli tsa sebopeho le tseo e seng tsa sebopeho sa sefofane.
Lits'ebetsong tse kang lisebelisoa tsa ho lulisa kapa likarolo tsa sebopeho sa fuselage, li-alloys tsa nickel li thusa ho fokotsa boima ba sefofane ha li ntse li boloka botšepehi ba likaroloana. Lifofane tse bobebe li ja mafura a fokolang, li fokotsa litšenyehelo tsa ts'ebetso ea lifofane le ho kenya letsoho maetong a tsitsitseng a moea.
Ho hanyetsa Mocheso le Bophelo ba Mokhathala
Lithempereichara tse feteletseng tse hlahisoang lienjineng tsa lifofane li hloka lisebelisoa tse sa hanetseng mocheso feela empa hape li boloka botšepehi ba tsona ba sebopeho ha nako e ntse e ea. Li-alloys tsa nickel li entsoe ho hanela mocheso o phahameng le ho ba le bophelo bo bolelele ba mokhathala, e leng se etsang hore e be tse loketseng ho sebelisoa likarolong tsa enjene. Mehaho ena e etsa bonnete ba hore li-alloys li khona ho sebetsana le libaesekele tse futhumatsang tse sa khaotseng tseo li tsamaisoang ho tsona nakong ea ho tloha, sefofane le ho lula.
Likarolo tse entsoeng ka li-alloys tsa nickel li bonts'a ho hanyetsa ka mokhoa o ikhethang ho creep (the deformation butle ea thepa tlas'a khatello), e leng ea bohlokoa lienjineng tse pepesehileng mocheso o sa khaotseng. Ka lebaka leo, likarolo li tšoarella nako e telele, e leng ho fokotsang tlhokahalo ea ho nkeloa sebaka khafetsa le ho matlafatsa tšireletso.
Qetello: Ke Hobane'ng ha Nickel Alloys e le Bohlokoa
Qetellong, li-alloys tsa nickel tse sa tloaelehang bakeng sa sefofane li bohlokoa hobane li fana ka matla, ho hanyetsa ho bola, ho mamella mocheso, le ho tšoarella ho hlokahalang ho finyella litlhoko tse thata tsa indasteri. Ho tloha ho lienjineri tsa sefofane ho ea ho likarolo tsa sebopeho, li-alloys tsa nickel li netefatsa hore lintlafatso tsa sepakapaka li ka tsoela pele ho sutumelletsa meeli ha li ntse li boloka polokeho le katleho. Bakeng sa baenjiniere le litsebi tsa thepa ea thepa lefapheng la lifofane, ho khetha motsoako o nepahetseng oa nickel ho ka etsa phapang eohle tshebetsong le ho tšepahala ha lisebelisoa tsa bona.
Ka ho kopanya lisebelisoa tsena tse tsoetseng pele meralong ea tsona, lik'hamphani tsa sepakapaka li ka etsa bonnete ba hore lihlahisoa tsa tsona li hlomelloa ho sebetsana le maemo a feteletseng ao li sebetsang ho tsona, li fana ka polokeho le boleng ba nako e telele.
