mocheso o phahameng oa tungsten alloy pitsa e qhibilihisang bakeng sa laboratori

Tlhaloso e Khutšoanyane:

Mocheso o phahameng oa tungsten alloy crucible ke sejana se ikhethileng se sebelisetsoang ho qhibiliha le ho ba le lisebelisoa ka mocheso o phahameng haholo. Hangata li-alloys tsa Tungsten li khethoa bakeng sa li-crucibles ka lebaka la boemo ba tsona bo phahameng ba ho qhibiliha, mocheso o motle oa mocheso le ho hanyetsa tlhaselo ea lik'hemik'hale.

Mocheso o phahameng ka ho fetisisa oa tungsten crucible ke ofe?

Mocheso o phahameng oa tungsten crucible o itšetlehile ka thepa e khethehileng ea tungsten alloy le mokhoa oa tlhahiso. Ka kakaretso, li-crucible tsa tungsten li khona ho mamella mocheso o fetang 3000 ° C (5432 ° F), e leng se etsang hore li tšoanelehe bakeng sa lisebelisoa tse hlokang mocheso o phahameng haholo, joalo ka ho qhibiliha le ho lahlela litšepe tse refractory, ceramics le mocheso o mong o phahameng. lisebelisoa. Leha ho le joalo, sebopeho se ikhethileng sa alloy le litšebelisano tse ka bang teng le thepa e ntseng e sebetsoa li hloka ho nahanoa ho netefatsa ts'ebetso ea crucible ho feta mocheso o lebelletsoeng.

A na u ka sebelisa crucible e tšoanang bakeng sa litšepe tse fapaneng?

E, li-crucibles tsa tungsten li ka sebelisoa ka litšepe tse fapaneng, empa ke habohlokoa ho nahana ka ho lumellana ha thepa ea crucible le tšepe e khethehileng e sebelisoang. Hangata li-crucible tsa Tungsten li khethoa bakeng sa ho hanyetsa mocheso o phahameng le ho senyeha ha lik'hemik'hale, ho etsa hore li tšoanelehe bakeng sa mefuta e sa tšoaneng ea ho qhibiliha ha tšepe le ho sebetsa. Leha ho le joalo, lirafshoa tse itseng kapa lialloys tsa tšepe li ka 'na tsa e-ba le litšebelisano tse khethehileng le thepa ea crucible, joalo ka karabelo e ka bang teng kapa tšilafalo, e ka amang boleng ba thepa e lokiselitsoeng. Ka hona, lisebelisoa tsa crucible li tlameha ho hlahlojoa ho lumellana le litšepe tse khethehileng le li-alloys tse sebelisoang ho netefatsa botšepehi ba ho qhibiliha le ho sebetsa. Ho phaella moo, ho hloekisa hantle le ho boloka li-crucibles pakeng tsa lisebelisoa tse fapaneng tsa tšepe ho bohlokoa ho qoba tšilafalo le ho netefatsa ts'ebetso e tsitsitseng.

Ke li-alloys life tse nang le ntlha e phahameng ea ho qhibiliha?

Li-alloys tse phahameng tsa melting li kenyelletsa:

1. Alloy e thehiloeng ho Tungsten: Tungsten e na le e 'ngoe ea libaka tse phahameng ka ho fetisisa tsa ho qhibiliha har'a litšepe tsohle,' me metsoako ea eona e kang tungsten-rhenium, tungsten-molybdenum, joalo-joalo e boetse e bontša lintlha tse phahameng tsa ho qhibiliha.

2. Li-alloys tse thehiloeng ho molybdenum: Molybdenum le li-alloys tsa eona, tse kang molybdenum titanium zirconium (TZM) le molybdenum lanthanum oxide (ML), li na le lintlha tse phahameng tsa ho qhibiliha 'me li sebelisoa ha ho sebelisoa mocheso o phahameng.

3. Li-alloys tsa tšepe tse refractory: Li-alloys tse nang le litšepe tse refractory tse kang niobium, tantalum, le rhenium li tsejoa ka libaka tsa tsona tse phahameng tsa ho qhibiliha 'me li sebelisoa libakeng tse phahameng tsa mocheso.

Li-alloys tsena li atisa ho sebelisoa sebakeng sa lifofane, ts'ireletso le liindasteri tse phahameng tsa mocheso tse hlokang lisebelisoa tse nang le mocheso o motle haholo.
