Indasteri ea likhoele
Tungsten e ile ea sebelisoa pele ho etsa likhoele tsa incandescent.Li-alloys tsa Tungsten rhenium li ithutile haholo.Theknoloji ea ho qhibiliha le ho etsa tungsten e boetse e ithutoa.Li-ingots tsa Tungsten li fumanoa ka ho qhibiliha ha li-arc le electron beam, 'me lihlahisoa tse ling li entsoe ka extrusion le polasetiki;Leha ho le joalo, ingot e qhibilihang e na le lijo-thollo tse mahoashe, polasetiki e futsanehileng, ho sebetsa ka thata le lihlahisoa tse fokolang, kahoo mokhoa oa ho qhibiliha oa polasetiki ha oa fetoha mokhoa o ka sehloohong oa tlhahiso.Ntle le tšebeliso ea mouoane oa lik'hemik'hale (CVD) le ho fafatsa ka plasma, e ka hlahisang lihlahisoa tse fokolang haholo, metallurgy ea phofo e ntse e le mokhoa o ka sehloohong oa ho etsa lihlahisoa tsa tungsten.
Indasteri ea ho phutha maqephe
Lilemong tsa bo-1960, ho ile ha etsoa lipatlisiso mabapi le ho qhibilihisa tungsten, metallurgy ea phofo le theknoloji ea ho sebetsa.Hona joale e ka hlahisa lipoleiti, maqephe, foil, mekoallo, liphaephe, lithapo le likarolo tse ling tsa profiled.
Ho mena lisebelisoa tsa mocheso o phahameng
Mocheso oa tšebeliso ea thepa ea tungsten o phahame, 'me ha o atlehe ho ntlafatsa matla a mocheso o phahameng oa tungsten feela ka ho sebelisa mokhoa oa ho matlafatsa tharollo.Leha ho le joalo, ho matlafatsa ho hasana (kapa pula) motheong oa ho matlafatsa tharollo e tiileng ho ka ntlafatsa haholo matla a mocheso o phahameng, 'me phello e matlafatsang ea ThO2 le likaroloana tsa ho hasana tsa HfC ke tsona tse ntle ka ho fetisisa.Li-alloys tsa W-Hf-C le W-ThO2 li na le matla a phahameng a mocheso le matla a ho thella hoo e ka bang 1900 ℃.Ke mokhoa o atlehang oa ho matlafatsa motsoako oa tungsten o sebelisoang ka tlase ho mocheso oa recrystallization ka ho amohela mokhoa oa ho sebetsa ka mofuthu ho thatafatsa ho hlahisa khatello ea maikutlo.Haeba terata e ntle ea tungsten e na le matla a phahameng a tsitsipano, sekhahla sa ts'ebetso ea ts'ebetso e felletseng ke
99.999% terata e ntle ea tungsten e bophara ba 0.015 mm, matla a tsitsitseng a 438 kgf/mm mocheso oa kamore
Har'a litšepe tse refractory, li-alloys tsa tungsten le tungsten li na le mocheso o phahameng ka ho fetisisa oa polasetiki oa brittle transition.Thempereichara ea phetoho ea polasetiki ea brittle ea thepa ea tungsten e sintered le e qhibilihisitsoeng e ka ba 150 ~ 450 ℃, e bakang mathata a ho sebetsa le ho sebelisoa, athe ea kristale e le 'ngoe ea tungsten e ka tlaase ho mocheso oa kamore.Litšila tsa lipakeng, li-microstructures le likarolo tsa alloying ka thepa ea tungsten, hammoho le ts'ebetso ea polasetiki le boemo bo holimo, li na le tšusumetso e kholo ho mocheso oa phetoho ea polasetiki ea brittle ea thepa ea tungsten.Ntle le hore rhenium e ka fokotsa haholo mocheso oa phetoho ea polasetiki ea brittle ea thepa ea tungsten, likarolo tse ling tsa alloy ha li na phello e fokolang ea ho fokotsa mocheso oa phetoho ea polasetiki ea brittle (bona ho matlafatsa tšepe).
Tungsten e na le khanyetso e mpe ea oxidation.Litšobotsi tsa eona tsa oxidation li tšoana le tsa molybdenum.Tungsten trioxide e futhumala kaholimo ho 1000 ℃, e bakang "koluoa" ea oxidation.Ka hona, lisebelisoa tsa tungsten li tlameha ho sireletsoa ke moea o hloekileng kapa o se nang moea ha o sebelisoa mocheso o phahameng.Haeba li sebelisoa sebakeng sa mocheso o phahameng oa oxidation, liphahlo tse sireletsang li tlameha ho eketsoa.
Indasteri ea libetsa tsa sesole e menang
Ka tsoelo-pele le tsoelo-pele ea mahlale, lisebelisoa tsa alloy tsa tungsten li fetohile lisebelisoa tsa ho etsa lihlahisoa tsa sesole kajeno, tse kang likulo, lihlomo le likhetla, lihlooho tsa likulo, liqhomane, lithunya, lihlooho tsa likulo, likoloi tse sa keneng likulo, litanka tse hlometseng, lifofane tsa sesole, lithunya. likarolo, lithunya, joalo-joalo The lihlomo ho phunya projectile e entsoeng ka tungsten alloy e ka phunyeletsa lihlomo le lihlomo tse entsoeng ka mahlakoreng a maholo, 'me ke sebetsa se seholo sa anti tank.
Li-alloys tsa tungsten ke li-alloys tse thehiloeng ho tungsten 'me li entsoe ka likarolo tse ling.Har'a litšepe, tungsten e na le sebaka se phahameng ka ho fetisisa sa ho qhibiliha, matla a mocheso o phahameng, khanyetso ea creep, conductivity ea mocheso, conductivity ea motlakase le ts'ebetso ea elektronike e hlahisoang, e leng tsa bohlokoa haholo, ntle le palo e kholo ea likopo ha ho etsoa li-carbides tse entsoeng ka samente le metsoako ea alloy.
Tungsten le li-alloys tsa eona li sebelisoa haholo indastering ea lisebelisoa tsa elektroniki le mohloli oa leseli la motlakase, hammoho le sebakeng sa sefofane, ho lahla, libetsa le likarolo tse ling ho etsa li-nozzles tsa rocket, hlobo e bolaeang, lihlomo tse phunyeletsang lihlomo, mabitso, lisebelisoa tsa ho futhumatsa le mocheso. lithebe.
