Alloy e thehiloeng ho tšepe / alloy e thehiloeng ho nickel / alloy e thehiloeng ho nickel / poleiti ea superalloy e hanyetsanang le Corrosion

Li-superalloys tse thehiloeng ho nickel ke sehlopha sa li-alloys tse matlafalitsoeng tsa pula tse sebetsang hantle libakeng tse phahameng tsa mocheso. Lintho tse babatsehang tse nang le mocheso o phahameng oa li-superalloy tse thehiloeng ho nickel li entse hore ho kenngoe ts'ebetsong ea li-alloys tsa sehlopha sena lits'ebetsong tse ngata tsa aerospace.

Iron-based superalloy ke mofuta oa superalloy. E tšoauoa ka ho eketsa lintlha tse ling motheong oa tšepe bakeng sa alloying. Tse tsamaellanang le li-superalloy tse thehiloeng ho tšepe ke li-superalloy tse thehiloeng ho nickel le li-superalloy tse thehiloeng ho cobalt.

Li-superalloys tse thehiloeng ho Cobalt ke lisebelisoa tse sebelisoang mocheso o phahameng le maemo a feteletseng a matla a phahameng a mocheso, ho hanyetsa kutu le ho se mamelle. Li-superalloys tse thehiloeng ho cobalt haholo-holo li entsoe ka likarolo tse kang cobalt, chromium, tungsten, nickel le aluminium.

Li-alloys tse hanyetsanang le Corrosion li fana ka keketseho ea matla a mochine, ho hanyetsa ho senyeha ha mocheso, le ho hanyetsa ho bola ha ho bapisoa le li-alloys tsa setso, tse hlokang tlhokomelo e fokolang le ho mamella maemo a thata. Boiteko bo ntse bo tsoela pele ho etsa li-alloys tse ncha tse hanyetsanang le kutu tse kang li-alloys tse kholo tse thehiloeng ka aluminium, le ho theha mekhoa e mecha ea ho etsa joalo ka radiolysis e sebelisang nano-particle synthesis bakeng sa sebopeho sa polycrystalline.

Ho hanyetsa mocheso o phahameng le ho hanyetsa kutu ha superalloy haholo-holo ho itšetlehile ka metsoako ea eona ea lik'hemik'hale le sebopeho. Ho nka mohlala oa Inconel718 nickel-based deformed superalloy e le mohlala, alloy e na le karolo ea γ matrix, karolo ea δ, carbide, le karolo e matlafalitsoeng ea γ 'le γ. Lik'hemik'hale le sebopeho sa matrix sa Inconel718 alloy li bontša matla a eona a mechine, lihlahisoa tsa 4 li molemo ka makhetlo a mangata le matla a 5 a molemo ka ho fetisisa ke tšepe ea 5 ea tšepe le matla ho feta tšepe ea 45 Sebopeho se tsitsitseng sa lattice le palo e kholo ea lintlha tse matlafatsang li tlatsetsa ho thepa ea eona e babatsehang ea mechine.

Ka lebaka la tikoloho e thata le e thata ea ho sebetsa ea li-superalloys, botšepehi ba sebaka se entsoeng ka mochine bo phetha karolo ea bohlokoa haholo ts'ebetsong ea eona. Leha ho le joalo, superalloy ke ntho e tloaelehileng e thata ho sebetsana le lintho tse bonahalang, boima ba eona bo matlafatsang micro-e matla bo phahame, tekanyo ea ho thatafala ha mosebetsi e tebile, 'me e na le khatello e phahameng ea ho kuta le conductivity e tlaase ea mocheso, matla a ho itšeha le mocheso oa ho itšeha sebakeng sa ho itšeha, hangata ho hlaha ts'ebetsong ea boleng bo tlaase ba holim'a metsi, tšenyo ea lisebelisoa e tebile haholo le mathata a mang. Tlas'a maemo a kakaretso a ho itšeha, bokaholimo ba superalloy bo tla hlahisa mathata a maholo haholo joalo ka lera le thata, khatello e setseng, lera le lesoeu, lera le letšo le lesela la deformation ea lijo-thollo.

Li-superalloy ke li-alloys tse hanyetsanang le mocheso tsa nickel, iron-nickel, le cobalt tse ka sebelisoang mochesong o phahameng, hangata> 70% ea mocheso oa tsona o qhibilihang. Li ka sebelisoa ka mocheso o fetang 1050°C le maeto a fihlang ho 1200°C. Sebopeho sena se hanyetsanang le mocheso se etsa hore e be mokhethoa ea loketseng bakeng sa Tungsten Carbide lits'ebetsong tsa Pick Up.

Mofuta o sebelisoang haholo oa Superalloy ke thepa e thehiloeng ho nickel e nang le chromium e ngata, tšepe, titanium, cobalt le likarolo tse ling tsa alloying. Joalo ka lihlopha tse ling tsa lisebelisoa tsa tšepe, thepa ea li-superalloy e ka fetoloa ka mefuta e fapaneng ea kalafo ea mocheso le / kapa ho koala le ho tima. Ha ho bapisoa le lihlopha tse ling tsa thepa, li-Superalloys li na le mocheso o phahameng ka ho fetisisa oa tšebeletso le boleng bo phahameng ka ho fetisisa ba boima. Matla a Superalloys a e etsa khetho e ntle ka ho fetisisa ea Carbide lits'ebetsong tse phahameng tsa bond (> 1kg).
