Thaum nws los txog rau cov hlau tungsten, feem ntau cov neeg thawj cov tshuaj tiv thaiv yuav yog "lub ci ntsa iab filament nyob rau hauv lub teeb teeb". Qhov tseeb, nws tsis yog. Tungsten tsis yog tsuas yog siv los ua cemented carbide, hu ua "tus hniav ntawm kev lag luam", tab sis kuj siv los ua cov tungsten ntshiab. Cov khoom siv tungsten lossis tungsten alloys.
Tungsten tus ID card
Tungsten yog ib qho nyiaj-dawb lustrous hlau nrog lub siab melting point thiab siab ceev. Nws tsis yog eroded los ntawm huab cua nyob rau hauv chav tsev kub, thiab nws cov tshuaj muaj pes tsawg leeg yog ruaj khov. Nws yog tsuas yog siv los tsim cov filament thiab high-speed txiav alloy steel, thiab superhard pwm, thiab kuj yog siv rau hauv cov cuab yeej kho qhov muag thiab cov cuab yeej tshuaj.
Taw qhia txog cov khoom siv tungsten
Lub melting point ntawm tungsten yog qhov siab tshaj plaws ntawm tag nrho cov hlau ntsiab, qhov ceev (19.3 g / cm3) yog siab heev, thiab hardness ntawm tungsten kuj siab heev. Piv txwv li, qhov nyuaj ntawm tungsten carbide yog ze rau ntawm pob zeb diamond. Tsis tas li ntawd, tungsten kuj muaj hluav taws xob zoo thiab thermal conductivity, me me expansion coefficient, thiab lwm yam ntxwv, yog li nws yog dav siv nyob rau hauv alloys, electronics, tshuaj lom neeg kev lag luam, thiab lwm yam teb, uas cemented carbide yog qhov loj tshaj plaws ntawm tungsten. .
Tungsten hlau yog ib yam hlau refractory, uas yog ib qho nyuaj rau kev tsim thiab nyuaj rau txheej txheem los ntawm hlau 3D tshuab luam ntawv. Cov txheej txheem tsim khoom ib txwm siv rau tungsten hlau yog nias tungsten carbide hmoov rau hauv cov duab uas xav tau thiab tom qab ntawd siv cov txheej txheem sintering los ua kom lub zog thiab ntom ntawm qhov. Tam sim no, cov tuam txhab me me hauv kev lag luam tab tom tshawb nrhiav kev tsim cov tungsten ntshiab thiab tungsten alloys los ntawm cov hmoov txaj txheej txheem-raws li electron beam melting (EBM) thiab xaiv laser melting (SLM) 3D luam ntawv thev naus laus zis, ob qho tib si ncaj qha. hlau 3D luam ntawv technologies.
Tungsten alloy qauv zaub
Cov luam tawm tungsten alloy muaj ultra-siab ceev, zoo glensity thiab thermal zog, thiab lub zog muaj peev xwm nqus tau cov duab hluav taws xob. Feem ntau siv hauv aerospace, tub rog tiv thaiv, kev lag luam nuclear, kev tsim khoom thiab cov hniav nyiaj hniav kub, thiab lwm yam.
