Titanium e na le thepa e mengata e ikhethang e e etsang khetho e nepahetseng bakeng sa lits'ebetso tse fapaneng indastering ea lifofane. Mehaho e joalo e kenyelletsa tekanyo ea eona e phahameng ea matla ho boima ba 'mele, ho hanyetsa ho hoholo ha kutu, le ts'ebetso e ntle haholo ka mocheso o phahameng le o tlase. Etsa lethathamo la fektheri ea titanium ea Xinyuanxiang, Tse latelang ke tse ling tsa ts'ebeliso ea bohlokoa ea titanium indastering ea lifofane:
LIKHALA TSA AEROSPACE TITANIUM SEBELISA JOANG HO LIFOFA?
Kaha titanium e bobebe ebile e na le matla a phahameng, e loketse ho sebelisoa ha ho etsoa likarolo tse fapaneng tsa sefofane. Tsena li kenyelletsa lireng tsa enjine, lifasteners, matlalo a mapheo, lisebelisoa tsa ho thella le likarolo tse ling tsa sebopeho.
Matla a phahameng le ho hanyetsa mocheso oa titanium ho etsa hore e be thepa e loketseng bakeng sa tlhahiso ea li-blades, li-rotor le likarolo tse ling tsa lienjiniere tsa lifofane. Likarolo tsa Titanium le tsona li hanana le kutu e bakoang ke likhase tse nang le asiti le mongobo oa enjene.
Titanium ke sesebelisoa se sebelisoang haholo ho etsa liboutu, li-screws le li-fasteners tse ling indastering ea lifofane. Matla a phahameng le khanyetso ea kutu ea tšepe ena e etsa hore e be khetho e nepahetseng bakeng sa li-fasteners tse hlokahalang libakeng tse thata, tse kang indasteri ea lifofane.
Kaha titanium e na le ts'ebetso e ikhethang mochesong o phahameng, e loketse ho sebelisoa litšireletsong tsa mocheso tse sireletsang likarolo tsa bohlokoa tsa sefofane. Thebe ea mocheso ea sefofa-sebakeng ke mohlala o babatsehang, moo e thusang ho fokotsa ho fetisa mocheso ho tloha enjeneng ho ea ho sefofa-sebakeng kaofela.
MOLEMO OA AEROSPACE TITANIUM ALLOYS
E 'ngoe ea melemo ea bohlokoa ka ho fetisisa ea li-alloys tsa titanium tsa sefofane ke karo-karolelano ea tsona e ikhethang ea boima ba 'mele. Titanium e matla joalo ka litšepe tse ngata empa e na le 60% feela ea boima ba eona. Thepa ena e lumella kaho ea lisebelisoa tsa sefofane tse bobebe empa li tiile, tse bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea mafura le ts'ebetso ka kakaretso.
Aerospace titanium alloys e na le khanyetso e ikhethang ea kutu. Ho hanyetsa hona ha lintho tsa tikoloho, tse kang mongobo le letsoai moeeng, ho tiisa nako e telele le ho tšepahala ha likarolo tsa sefofane. Lisebelisoa tse thibelang ho bola li bohlokoa ka ho khetheha bakeng sa lifofane, tseo hangata li tobanang le maemo a sa tšoaneng a leholimo.
Li-alloys tsa Titanium li boloka thepa ea tsona ea mochine mochesong o phahameng, e leng ntho ea bohlokoa bakeng sa likarolo tse sebetsang ka har'a mocheso o feteletseng o hlahisoang ke lienjini tsa lifofane. Bokhoni ba ho mamella mocheso o phahameng ntle le ho senyeha ho hoholo ho netefatsa polokeho le ts'ebetso ea likarolo tsena tsa bohlokoa.
Li-alloys tsa Titanium li tsejoa ka ho hanyetsa mokhathala, e leng ho fokotseha ha thepa tlas'a cyclic loading. Thepa ena e bohlokoa bakeng sa lisebelisoa tse kang lisebelisoa tsa ho theola sefofane tse nang le khatello ea maikutlo khafetsa nakong ea sefofane se seng le se seng. Ho hanyetsa mokhathala oa titanium ho kenya letsoho ho sireletseha ka kakaretso le nako ea bophelo ea lifofane.
Le hoja e sa amane ka ho toba le lifofane, biocompatibility ea titanium e lokela ho boleloa. Ke lintho tse se nang chefo le tse sa sebetseng ka biologically, tse etsang hore li tšoanelehe bakeng sa li-implants tsa bongaka. Likarolo tse ngata tsa lifofane li hlahisoa ka lebaka la lipatlisiso le nts'etsopele ea indasteri ea sepakapaka, e ruang molemo ho biocompatibility ea titanium.
Lefapheng la lifofane, limaraka tse 'maloa tsa titanium li sebelisoa ho latela litlhoko tse khethehileng tsa karolo kapa sebopeho sa lihlahisoa tse tloaelehileng tsa titanium. Limaraka tse peli tse sebelisoang haholo ke:
Titanium ea Kereiti ea 5, e tsejoang hape e le Ti-6Al-4V, ke motsoako oa titanium o sebelisoang ka ho fetesisa bofofising. E na le 90% ea titanium, 6% ea aluminium, le 4% vanadium. Alloy ena e fana ka motsoako o babatsehang oa matla a phahameng, ho hanyetsa kutu le ho hanyetsa mocheso. Letlapa la titanium la GR5 hangata le sebelisoa likarolong tsa sebopeho sa sefofane, likarolo tsa enjene le li-fasteners ka lebaka la thepa ea eona e makatsang.
Titanium ea Grade 2, kapa Ti-CP (Commercially Pure), ke mofuta o hloekileng oa titanium o nang le lintlha tse fokolang tsa likarolo tsa motsoako. E nkoa e le ea bohlokoa haholo bakeng sa khanyetso ea eona e ikhethang ea kutu, e e etsa khetho e nepahetseng bakeng sa likarolo tse pepesehileng tikolohong e mabifi. Titanium ea Kereiti ea 2, joalo ka poleiti ea titanium ea GR2 hangata e sebelisoa lifofaneng moo ho bola e leng ntho e tšoenyang haholo, joalo ka li-fasteners, lisebelisoa tsa ho lulisa, le li-exhaust systems.
