Tungsten yog cov hlau tsis tshua muaj, uas zoo li hlau. Nws tau dhau los ua ib qho ntawm cov khoom siv tseem ceeb tshaj plaws hauv kev lag luam niaj hnub no, kev tiv thaiv hauv teb chaws thiab kev siv thev naus laus zis vim tias nws qhov siab melting point, siab hardness, zoo heev corrosion kuj thiab zoo hluav taws xob thiab thermal conductivity. Dab tsi yog daim ntawv thov tshwj xeeb ntawm tungsten?
1, Alloy teb
hlau
Vim nws qhov siab hardness thiab siab ceev, tungsten yog ib qho tseem ceeb ntawm cov hlau vim nws tuaj yeem txhim kho lub zog, hardness thiab hnav tsis kam ntawm cov hlau. Nws yog dav siv nyob rau hauv zus tau tej cov steels. Feem ntau cov tungsten uas muaj cov hlau muaj xws li high-speed steel, tungsten steel thiab tungsten cobalt hlau nplaum. Lawv tsuas yog siv los tsim ntau yam cuab yeej, xws li laum khoom, milling cutters, poj niam pwm thiab txiv neej pwm.
Tungsten carbide raws li cemented carbide
Tungsten carbide muaj siab hnav tsis kam thiab refractory, thiab nws hardness yog ze rau pob zeb diamond, yog li nws yog feem ntau siv nyob rau hauv zus tau tej cov cemented carbide. Tungsten carbide raws li cemented carbide feem ntau tuaj yeem muab faib ua plaub pawg: tungsten carbide cobalt, tungsten carbide titanium carbide cobalt, tungsten carbide titanium carbide tantalum (niobium) - cobalt thiab steel bonded cemented carbide. Lawv tsuas yog siv los tsim cov cuab yeej txiav, cov cuab yeej mining thiab hlau kos duab tuag.

Hnav resistant alloy
Tungsten yog cov hlau refractory nrog lub siab tshaj plaws melting point (feem ntau siab dua 1650 ℃), uas muaj hardness siab, yog li nws yog feem ntau siv los tsim lub zog kub thiab hnav-resistant alloys, xws li alloys ntawm tungsten thiab chromium, cobalt thiab carbon, uas feem ntau siv los tsim cov khoom hnav-tiv taus xws li lub valve ntawm aeroengine thiab turbine impeller, Cov alloys ntawm tungsten thiab lwm yam hlau refractory (xws li tantalum, niobium, molybdenum thiab rhenium) feem ntau yog siv los tsim cov thermal zog qhov chaw xws li foob pob hluav taws. nozzle thiab engine.
High precision gravity alloy
Tungsten tau dhau los ua cov khoom siv zoo tshaj plaws rau kev tsim cov khoom sib nqus tshwj xeeb vim nws qhov siab ceev thiab siab hardness. Raws li cov yam ntxwv sib txawv thiab kev siv, cov hlau nplaum tshwj xeeb no tuaj yeem muab faib ua W-Ni-Fe, W-Ni-Cu, W-Co, w-wc-cu, W-Ag thiab lwm yam. Lawv feem ntau siv los tsim cov ntaub ntawv sib cuag xws li armor, cov ntawv kub dissipation, riam hloov, Circuit Court breaker thiab lwm yam vim lawv qhov loj tshwj xeeb lub ntiajteb txawj nqus, siab zog, siab thermal conductivity, zoo hluav taws xob conductivity thiab superior kev ua tau zoo.
2, Electronic teb
Tungsten yog dav siv nyob rau hauv electronics thiab fais fab kev lag luam vim nws muaj zog plasticity, tsawg evaporation tus nqi, siab melting point thiab muaj zog electron emission muaj peev xwm. Piv txwv li, tungsten filament muaj luminous npaum li cas thiab lub neej ntev kev pab cuam, thiab feem ntau yog siv los ua ntau yam noob filaments, xws li incandescent teeb, iodine tungsten teeb thiab thiaj li nyob. Tsis tas li ntawd, tungsten hlau kuj tuaj yeem siv los tsim cov cathode ncaj qha kub thiab kab sib chaws ntawm hluav taws xob oscillation raj thiab cathode rhaub hauv ntau yam khoom siv hluav taws xob.
3, Tshuaj lom neeg kev lag luam
Tungsten compounds feem ntau yog siv los tsim qee hom xim, pigments, inks, lubricants thiab catalysts. Piv txwv li, sodium tungstate feem ntau yog siv rau hauv kev tsim cov hlau tungsten, tungstic acid thiab tungstate, nrog rau dyes, pigments, inks, electroplating, thiab lwm yam; Tungstic acid feem ntau yog siv los ua mordant thiab dye hauv kev lag luam textile thiab catalyst rau kev npaj siab octane roj av hauv kev lag luam tshuaj; Tungsten disulfide feem ntau yog siv rau hauv cov organic synthesis, xws li cov roj nplua nyeem thiab cov catalyst hauv kev npaj cov roj hluavtaws hluavtaws; Bronze tungsten oxide yog siv nyob rau hauv painting.

4 、 Kev kho mob teb
Vim nws cov hardness siab thiab ceev, tungsten alloy yog heev haum rau kev kho mob teb xws li X-ray thiab hluav taws xob tiv thaiv. Cov khoom siv kho mob tungsten alloy feem ntau suav nrog X-ray anode, anti scattering phaj, lub thawv ntim xov tooj cua thiab lub thawv ntim tshuaj tiv thaiv.
5. Tub rog teb
Vim nws cov khoom tsis muaj tshuaj lom thiab ib puag ncig zoo, cov khoom siv tungsten tau siv los hloov cov hlau lead yav dhau los thiab cov khoom siv uranium depleted los ua cov mos txwv warheads, thiaj li yuav txo tau cov pa phem ntawm cov ntaub ntawv tub rog mus rau ecological ib puag ncig. Tsis tas li ntawd, vim muaj cov yam ntxwv ntawm qhov muaj zog hardness thiab zoo kub tsis kam, tungsten tuaj yeem ua rau kev sib ntaus sib tua ntawm cov khoom siv tub rog npaj tau zoo dua. Cov khoom siv tungsten siv hauv tub rog feem ntau suav nrog cov mos txwv tungsten alloy thiab kinetic zog armor tho cov mos txwv.
Ntxiv nrog rau cov teb saum toj no, tungsten tseem tuaj yeem siv rau hauv aerospace, navigation, atomic zog, nkoj tsim, kev lag luam tsheb thiab lwm yam.
