Sehlahisoa SEHLOOHO
GH4049 ke Ni-Co-Cr e thehiloeng ho pula e thatafatsang deformation mocheso o phahameng oa motsoako o nang le mocheso oa tšebeletso o ka tlase ho 950 ℃. Alloy e na le khanyetso e ntle ea oxidation tlas'a 1000 ℃ le matla a phahameng a mocheso tlas'a 950 ℃. E loketse tlhahiso ea likhaba tse sebetsang tsa turbine ea khase ka mocheso o sebetsang oa 850 ℃ ~ 950 ℃. Lihlahisoa tse ka sehloohong li kenyelletsa litšepe tse kolobisitsoeng le tse ferekaneng, le li-blade tsa turbine tsa fored. Ha ho bapisoa le li-alloys tse thehiloeng ho nickel tsa lits'ebetso tse ts'oanang, polasetiki e chesang ea alloy ha e sebetse hantle, empa ka mor'a ho qhibiliha ha electroslag kapa vacuum arc remelting, polasetiki ea eona ea ho sebetsa e ka ntlafatsoa, 'me matla a ts'ebetso ea 1000 ℃ -1170 ℃ a eketseha ka makhetlo a 1 ~ 3.
Sesebelisoa sa sehlahisoa
Alloy e 'nile ea sebelisoa ha ho etsoa li-blades tsa turbine ea lifofane le likarolo tse ling tsa mocheso o phahameng oa ho jara. Kamora nako e telele ea tlhahiso le ts'ebeliso, e fetohile e 'ngoe ea lisebelisoa tsa makhasi tse sebelisoang haholo.
