Liphapang tsa sebopeho sa lintho tse bonahalang
Li-alloys tse thehiloeng ho cobalt li sebelisa cobalt (Co), chromium (Cr), molybdenum (Mo), joalo-joalo e le lintlha tse ka sehloohong, tseo cobalt e ikarabellang bakeng sa karolo e phahameng, le tšepe e itseng (Fe), carbon (C) le likarolo tse ling hape li eketsoa; nickel-based Alloy e sebelisa nickel (Ni) e le ntho e ka sehloohong, hape e eketsa chromium (Cr), molybdenum (Mo), koporo (Cu), titanium (Ti), niobium (Nb) le likarolo tse ling.
Liphapang tsa ts'ebetso
Li-alloys tse thehiloeng ho cobalt li na le mesebetsi e metle ea ho thatafatsa le ho nolofatsa, 'me li bonolo ho etsoa ka libopeho tse fapaneng. Li loketse likarolo tsa machining ho sebelisa li-alloys tse thehiloeng ho cobalt. Li-alloys tse thehiloeng ho nickel li na le ts'ebetso e ntle 'me li bonolo ho theha, extrusion le rotor form processing,' me li loketse likarolo tsa machining. Ntlafatso le ntlafatso ea mechini ea matla a lebelo le holimo e sebelisang li-alloys tse thehiloeng ho nickel.
1.Kalafo ea mocheso: Ka bobeli li-alloys tse phahameng tsa mocheso li hloka phekolo ea mocheso. Ka bobeli ba amohela mokhoa oa kalafo oa mocheso oa kalafo e tiileng ea tharollo + kalafo ea botsofali. Ho rarahana ha mokhoa oa phekolo ea mocheso ho tšoana.
2. Weldability: Ka bobeli li-alloys tse nang le mocheso o phahameng li na le li-weldability tse ntle. Nakong ea ho tjheseletsa seal seal, mocheso o bonolo ho bokella le ho baka deformation. Ho khothalletsoa ho sebelisa lisebelisoa tse thehiloeng ho cobalt, tse nang le conductivity e phahameng ea mocheso, mocheso o matla oa mocheso, coefficient e nyenyane ea ho atolosa, le deformation e nyenyane. , matla a fusion ea welding a betere.
3.Ho fetola ts'ebetso: Phetoho e khotsofatsang e ka etsoa.
Ka bobeli li-alloys tsa mocheso o phahameng li na le ts'ebetso e ntle.
Phapang ea ts'ebetso
1.Corrosion resistance:
Li-alloys tse thehiloeng ho Cobalt li na le khaello e ntle ea ho apara, ho hanyetsa kutu le thepa e phahameng ea mocheso, 'me li ka boloka ts'ebetso e tsitsitseng libakeng tse feteletseng tse kang acid e matla, alkali e matla, mocheso o phahameng le khatello e phahameng,' me li loketse ho etsa likarolo tse hlokang ho mamella meroalo e phahameng le maemo a feteletseng;
Li-alloys tse thehiloeng ho nickel li na le khanyetso e ntle ea kutu 'me li ka boloka botsitso le botšepehi mecheng ea litaba tse sa tšoaneng tse senyang. Li boetse li na le thepa e ntle ea mocheso o phahameng 'me li khona ho boloka matla le ho tiea ha maemo a phahameng a mocheso. Empa ha e loketse mecha ea litaba e senyang haholo.
2. Thermal botsitso: Li-alloys tse thehiloeng ho cobalt li na le lisebelisoa tse betere tsa mocheso o phahameng ho feta li-alloys tse thehiloeng ho nickel 'me li ka sebelisoa mocheso o phahameng ka holimo ho 1200 ° C nako e telele, ha li-alloys tse thehiloeng ho nickel hangata li ka sebelisoa feela ho pota 1000 ° C. Li-alloys tse thehiloeng ho cobalt li na le lintlha tse phahameng tsa ho qhibiliha le ho tsamaisoa ha mocheso, katoloso e nyane ea mocheso ka mor'a ho futhumatsa, 'me e na le melemo ea botsitso ba mocheso; Li-alloys tse thehiloeng ho nickel li na le khanyetso e ntle ea oxidation le corrosion, empa libakeng tse phahameng tsa mocheso, cobalt The base alloy e na le khanyetso e ntle ea mocheso o phahameng oa mocheso le mocheso o phahameng oa mocheso.
3.Matla a mochine: Li-alloys tse thehiloeng ho cobalt li na le matla a phahameng a mocheso le mocheso o motle oa ho hanyetsa mokhathala, ha li-alloys tse thehiloeng ho nickel li na le ductility le ts'ebetso e ntle haholo, empa matla a tsona a mocheso o phahameng le ho hanyetsa mokhathala oa mocheso li tlaase ho feta li-alloys tse thehiloeng ho cobalt. . Ka mocheso oa kamore, matla a li-alloys tse thehiloeng ho cobalt a fokotseha hanyane, empa bolelele bo boholo; Li-alloys tse thehiloeng ho nickel li na le matla a holimo, empa li brittle, 'me li lokela ho sebelisoa ka hloko libakeng tse nang le tšusumetso. Lithempereichara tse phahameng, ha mocheso o le 650 ° C, li-alloys tse thehiloeng ho nickel li na le matla a holimo, empa hape li brittle, 'me li atisa ho robeha ha li sebelisoa maemong a ts'oaetso. Ha mocheso o nyolohela ho 900 ° C, superalloy e thehiloeng ho nickel e ke ke ea hlola e sebelisoa, ha superalloy e thehiloeng taemane e ntse e e-na le matla a itseng.
4.Mechanical satalla: Seo ho thoeng ke ho satalla ke bokhoni ba thepa ea ho hanyetsa deformation. Ho satalla ha li-alloys tse thehiloeng ho nickel ho tlase ho feta li-alloys tse thehiloeng ho cobalt mefuteng eohle ea mocheso.
Umasene
Li-alloys tse thehiloeng ho cobalt li atisa ho sebelisoa ho etsa likarolo le likarolo tse sa tšoaneng tlas'a maemo a sebetsang a sa senyeheng, a sa kutung, a mocheso o phahameng le a sa sebetseng; li-alloys tse thehiloeng ho nickel li sebelisoa haholo ho lifofane, sefofaneng, matla, leoatleng, ts'ireletso ea tikoloho le masimo a mang, haholo-holo Ho hlahisa likarolo tsa bohlokoa tse kang li-blade tsa turbine le likamore tse tukang lienjineng tsa moea.
