(Kev tso tawm ntawm cov khoom siv tungsten mus rau lub substrate los tsim ib zaj duab xis nyias)

3. kub isostatic nias

(Kev kho qhov ntom ntom ntawm cov khoom siv tungsten los ntawm ib txhij siv qhov kub thiab txias)

4. Txoj kev Melting

(Siv kub siab kom yaj tag nrho tungsten, thiab tom qab ntawd ua cov khoom siv los ntawm kev casting lossis lwm yam txheej txheem tsim)

5. Tshuaj vapor deposition

(Txoj kev ntawm decomposing gaseous precursor ntawm kub thiab tso tungsten rau substrate)

Daim ntawv thov

Nyias zaj duab xis txheej tshuab: Tungsten lub hom phiaj kuj tau siv dav hauv cov txheej txheem txheej txheej txheej txheem xws li lub cev vapor deposition (PVD) thiab tshuaj vapor deposition (CVD). Nyob rau hauv PVD txheej txheem, tungsten lub hom phiaj yog bombarded los ntawm high-zog ions, evaporated thiab tso rau ntawm qhov chaw ntawm lub wafer, tsim ib tug tuab tungsten zaj duab xis. Cov yeeb yaj kiab no muaj qhov tawv tawv heev thiab hnav tsis kam, uas tuaj yeem txhim kho cov neeg kho tshuab lub zog thiab ua haujlwm ntev ntawm cov khoom siv semiconductor. Nyob rau hauv CVD txheej txheem, tungsten lub hom phiaj cov khoom yog tso rau saum npoo ntawm wafer los ntawm cov tshuaj tiv thaiv ntawm qhov kub thiab txias los tsim ib txheej txheej, uas yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv high-power thiab high-frequency semiconductor li.

FAQS

Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm cov khoom siv tungsten?

Molybdenum feem ntau yog siv los ua cov khoom siv hauv kev mammography vim nws cov khoom muaj txiaj ntsig zoo rau kev tshuaj xyuas cov ntaub so ntswg ntawm lub mis. Molybdenum muaj tus lej atomic tsawg, uas txhais tau hais tias X-rays nws tsim yog qhov zoo tagnrho rau cov duab mos xws li lub mis. Molybdenum tsim cov yam ntxwv X-rays ntawm qis zog, ua rau lawv zoo tagnrho rau kev soj ntsuam qhov sib txawv me me hauv cov ntaub so ntswg ntawm lub mis.

Tsis tas li ntawd, molybdenum muaj cov thermal conductivity zoo, uas yog ib qho tseem ceeb hauv cov khoom siv mammography uas rov ua X-ray raug ntau. Lub peev xwm los ua kom cov cua sov kom zoo pab tswj kev ruaj ntseg thiab kev ua haujlwm ntawm X-ray raj nyob rau lub sijhawm ntev ntawm kev siv.

Zuag qhia tag nrho, kev siv cov molybdenum ua cov khoom siv hauv kev mammography pab txhim kho qhov zoo ntawm lub mis imaging los ntawm kev muab cov khoom X-ray tsim nyog rau daim ntawv thov tshwj xeeb no.

Dab tsi yog qhov tsis zoo ntawm cov khoom siv tungsten?

High brittleness: tungsten lub hom phiaj cov ntaub ntawv muaj siab brittleness thiab muaj kev cuam tshuam thiab kev co, uas yuav ua rau puas.
Tus nqi tsim khoom siab: Tus nqi tsim khoom ntawm tungsten lub hom phiaj yog qhov siab vim tias nws cov txheej txheem tsim khoom yuav tsum muaj cov txheej txheem nyuaj thiab cov cuab yeej ua haujlwm siab.
Vuam nyuaj: Vuam tungsten lub hom phiaj cov ntaub ntawv yog ib qho nyuaj thiab yuav tsum tau tshwj xeeb vuam txheej txheem thiab cov tswv yim los xyuas kom meej cov kev ncaj ncees ntawm lawv cov qauv thiab kev ua tau zoo.
High coefficient ntawm thermal expansion: Tungsten lub hom phiaj cov khoom muaj ib tug siab coefficient ntawm thermal expansion, yog li thaum siv nyob rau hauv high kub ib puag ncig, yuav tsum tau them nyiaj mloog mus rau nws loj hloov thiab cuam tshuam ntawm thermal stress.
