Tungsten Electrode bakeng sa TIG Welding
Sebakeng se seholo sa mahlale a morao-rao le indasteri, seketsoana sa tungsten se hlaha e le sesebelisoa se ikhethang se nang le lits'ebetso tse fapaneng le tsa bohlokoa.
Likepe tsa Tungsten li entsoe ka tungsten, tšepe e tsejoang ka thepa ea eona e ikhethang. Tungsten e na le sebaka se phahameng haholo sa ho qhibiliha, ho ts'oaroa ho matla ha mocheso, le khanyetso e makatsang khahlano le karabelo ea lik'hemik'hale. Litšobotsi tsena li etsa hore e be thepa e loketseng bakeng sa ho etsa lijana tse ka mamellang maemo a feteletseng.
E 'ngoe ea lits'ebetso tsa mantlha tsa liketsoana tsa tungsten ke lebaleng la deposition ea vacuum. Mona, seketsoana se futhumatsoa ho isa mochesong o phahameng ka har'a phaposi e hloekileng. Lisebelisuoa tse behiloeng ka sekepeng lia fetoha mouoane ebe li behoa holim'a substrate, 'me li etsa lifilimi tse tšesaane tse nang le botenya le sebopeho se nepahetseng. Ts'ebetso ena e bohlokoa ha ho etsoa li-semiconductors. Mohlala, ha ho etsoa li-microchips, likepe tsa tungsten li thusa ho beha likarolo tsa lisebelisoa tse kang silicon le tšepe, ho theha potoloho e rarahaneng e matlafatsang lefatše la rona la dijithale.
Sebakeng sa optics, liketsoana tsa tungsten li phetha karolo ea bohlokoa. Li sebelisetsoa ho beha liphahlo holim'a lilense le liipone, ho ntlafatsa ponahalo ea tsona le transmissivity. Sena se lebisa ts'ebetsong e ntlafetseng ea lisebelisoa tsa optical tse kang lik'hamera, libonela-hōle le lisebelisoa tsa laser.
Indasteri ea lifofane le eona e rua molemo ho likepe tsa tungsten. Likarolo tse pepesehileng mochesong o phahameng le tikolohong e thata nakong ea maeto a sepaka-pakeng li etsoa ka ho sebelisoa ha li-deposition tse laoloang tse tsamaisoang ke likepe tsena. Lisebelisoa tse behiloeng ka mokhoa ona li fana ka ho hanyetsa mocheso o phahameng le ho tšoarella.
Likepe tsa Tungsten li boetse li sebelisoa ho nts'etsopele ea lisebelisoa tse ncha tsa ho boloka matla le ho fetola. Ba thusa ka ho kopanya le ho khetholla lisebelisoa tsa libeteri le lisele tsa mafura, ho khanna ho batla litharollo tse sebetsang hantle le tse tsitsitseng tsa matla.
Lipatlisisong tsa mahlale a lintho tse bonahalang, li nolofalletsa boithuto ba phetoho ea mekhahlelo le thepa ea lintho tse tlas'a maemo a laoloang a mouoane. Sena se thusa bo-rasaense ho utloisisa le ho laola boitšoaro ba lisebelisoa boemong ba athomo.
Ho feta moo, ha ho etsoa liphahlo tse khethehileng bakeng sa lits'ebetso tse fapaneng tsa indasteri, likepe tsa tungsten li netefatsa ts'ebeliso e ts'oanang le e nepahetseng ea lisebelisoa, ho ntlafatsa ts'ebetso le bophelo bo bolelele ba libaka tse koahetsoeng.
Seketsoana sa tungsten ke karolo ea bohlokoa ho mahlale a mangata a tsoetseng pele. Bokhoni ba eona ba ho nolofatsa ho beoa ha thepa e laoloang le moea oa mouoane ho etsa hore e be mothusi oa bohlokoa oa tsoelopele mafapheng a mangata, ho bopa bokamoso ba mahlale le indasteri.
Lihlahisoa tsa rona tse tloaelehileng
Re hlahisa liketsoana tsa mouoane tse entsoeng ka molybdenum, tungsten le tantalum bakeng sa ts'ebeliso ea hau:
Likepe tsa mouoane oa Tungsten
Tungsten ha e bola ha e bapisoa le litšepe tse ngata tse qhibilihisitsoeng, 'me e na le sebaka se phahameng ka ho fetisisa sa ho qhibiliha ho feta litšepe tsohle, e mamella mocheso haholo. Re etsa hore thepa e se ke ea bola le ho feta le ho ba e tsitsitseng ka ho sebelisa li-dopants tse khethehileng tse kang potassium silicate.
Likepe tsa molybdenum evaporation
Molybdenum ke tšepe e tsitsitseng ka ho khetheha 'me e boetse e loketse mocheso o phahameng. E tšetsoe ka lanthanum oxide (ML), molybdenum e na le ductile le ho feta ho senya. Re eketsa yttrium oxide (MY) ho ntlafatsa ts'ebetso ea mochini oa molybdenum
Likepe tsa mouoane tsa Tantalum
Tantalum e na le khatello e tlase haholo ea mouoane le lebelo le tlase la mouoane. Ntho e khahlang haholo ka thepa ena, leha ho le joalo, ke khanyetso ea eona e phahameng ea kutu.
Cerium-Tungsten Electrode
Li-Electrode tsa Cerium-Tungsten li na le ts'ebetso e ntle ea ho qala arc tlas'a maemo a tlase a crrrent. Arc current e tlase, ka hona li-electrode li ka sebelisoa bakeng sa ho cheselletsa phala, likarolo tse se nang letheba le tse ntle.
