Mhoro, chinangwa chiri seizvi
Filament industry
Tungsten yakatanga kushandiswa kugadzira incandescent filaments.Tungsten rhenium alloys akadzidzwa zvakanyanya.Iyo yekunyungudika uye kugadzira tekinoroji ye tungsten inodzidzwa zvakare.Tungsten ingots inowanikwa neanodyiwa arc uye erekitironi danda kunyunguduka, uye zvimwe zvigadzirwa zvinogadzirwa neextrusion uye epurasitiki kugadzirisa;Nekudaro, iyo ingot yakanyunguduka ine coarse zviyo, yakashata mapurasitiki, yakaoma kugadzirisa uye goho rakaderera, saka iyo yakanyunguduka yepurasitiki yekugadzirisa haina kuve nzira huru yekugadzira.Pamusoro pemakemikari vapor deposition (CVD) uye kupfapfaidza kweplasma, iyo inogona kuburitsa zvigadzirwa zvishoma, hupfu simbi ichiri nzira huru yekugadzira tungsten zvigadzirwa.
Folding sheet industry
Muma1960, tsvagiridzo yakaitwa pa tungsten kunyunguduka, poda simbi uye kugadzira tekinoroji.Iye zvino inogona kugadzira mahwendefa, mapepa, foils, mbariro, mapaipi, waya uye zvimwe zvikamu zvakapetwa.
Kupeta zvinhu zvepamusoro-tembiricha
Iyo tembiricha yekushandisa ye tungsten zvinhu yakakwira, uye haishande kuvandudza yakanyanya tembiricha simba re tungsten nekushandisa nzira yekusimbisa mhinduro.Nekudaro, kupararira (kana kunaya) kusimba pahwaro hwekusimba kwemhinduro kusimba kunogona kuvandudza zvakanyanya kusimba kwekushisa kwepamusoro, uye kusimbaradza kweThO2 uye inonaya HfC dispersion particles ndiyo yakanyanya kunaka.W-Hf-C uye W-ThO2 alloys ane yakakwirira tembiricha simba uye zvinokambaira simba kunosvika 1900 ℃.Iyo inzira inoshanda yekusimbisa tungsten alloy inoshandiswa pazasi recrystallization tembiricha nekutora nzira yekudziya basa kuomesa kuburitsa kusimba kusimba.Kana iyo yakanaka tungsten waya ine yakakwira tensile simba, iyo yakazara yekugadzirisa deformation rate ndeye
99.999% yakanaka tungsten waya ine dhayamita ye0.015 mm, simba rekusimba re438 kgf/mm patembiricha yekamuri
Pakati pesimbi dzinoramba, tungsten uye tungsten alloys ane epamusoro epurasitiki brittle shanduko tembiricha.Iyo yepurasitiki brittle shanduko tembiricha ye sintered uye yakanyungudutswa polycrystalline tungsten zvinhu ingangoita 150 ~ 450 ℃, zvichikonzera kunetsa mukugadzirisa nekushandisa, nepo iyo yekristaro tungsten yakadzikira pane tembiricha yekamuri.Interstitial tsvina, microstructures uye alloying zvinhu mu tungsten zvinhu, pamwe nepurasitiki kugadzirisa uye pamusoro mamiriro, ane pesvedzero huru pane epurasitiki brittle shanduko tembiricha ye tungsten zvinhu.Kunze kwekuti rhenium inogona kudzikisa zvakanyanya kupisa kwepurasitiki brittle transition ye tungsten zvinhu, zvimwe zviwanikwa zvealloy zvine chekuita nekudzikisa tembiricha yepurasitiki brittle transition (ona kusimbaradza kwesimbi).
Tungsten ine urombo oxidation kuramba.Maitiro ayo oxidation akafanana neemolybdenum.Tungsten trioxide inoputika pamusoro pe1000 ℃, zvichikonzera "njodzi" oxidation.Naizvozvo, tungsten zvinhu zvinofanirwa kuchengetedzwa nevacuum kana inert mhepo kana zvichishandiswa pakupisa kwakanyanya.Kana iyo yakashandiswa mumhepo yepamusoro-yekushisa oxidation, machira ekudzivirira anofanira kuwedzerwa.
Kupeta indasitiri yezvombo zvehondo
Nekuvandudzwa uye kufambira mberi kwesainzi, tungsten alloy zvinhu zvave zvigadzirwa zvekugadzira zvigadzirwa zvemauto nhasi, zvakaita semabara, nhumbi dzokurwa uye matemba, misoro yepfuti, magirinedhi, pfuti, misoro yebara, mota dzisingapindi mabara, matangi ezvombo, ndege dzehondo, pfuti. zvidimbu, pfuti, nezvimwewo. Iyo yezvombo inobaya projectile yakagadzirwa ne tungsten alloy inogona kupaza nepakati pezvombo uye inoumbwa nhumbi dzokurwa dzine hombe yekurerekera kona, uye ndicho chikuru chinorwisa tank chombo.
Tungsten alloys ma alloys akavakirwa pa tungsten uye anoumbwa nezvimwe zvinhu.Pakati pesimbi, tungsten ine nzvimbo yepamusoro yekunyungudika, kusimba kwekushisa kwepamusoro, kutsika kwemhepo, kupisa kwemhepo, kushandiswa kwemagetsi uye electron emission performance, iyo inokosha zvikuru, kunze kwehuwandu hwekushandisa mukugadzira simende carbides uye alloy additives.
Tungsten nema alloys ayo anoshandiswa zvakanyanya mumaindasitiri emagetsi nemagetsi emwenje sosi, pamwe neaerospace, casting, zvombo uye mamwe masekete kugadzira maroketi nozzles, anofa-casting molds, nhumbi dzinobaya bullet cores, kudhumhana, kupisa zvinhu uye kupisa. nhovo.
