Cov Tungsten Filaments ntawm Electron Beam
Kev piav qhia txog khoom
Tungsten filaments muaj lub melting point siab, resistivity siab, lub zog zoo, thiab vapor pressure qis, thiab siv tau rau hauv electron beam evaporation systems. Electron beam tungsten filaments tuaj yeem tiv taus qhov kub siab uas tsim thaum lub sijhawm vaporization, ua kom ntseeg tau tias kev ua haujlwm ntawm cov txheej txheem evaporation txhim khu kev qha thiab ua haujlwm tau zoo.
Cov filaments tungsten uas muaj hluav taws xob yog ib qho tseem ceeb hauv cov tshuab nqus tsev vacuum deposition, uas siv lub zog ntawm electron bombardment los ua kom cov khoom siv ua pa. Cov txheej txheem ua pa no tsim cov kwj deg ntawm cov atoms lossis molecules, uas tso cov zaj duab xis nyias nyias nrog kev sib xws zoo, qhov ceev, thiab kev huv.
Peb tsim cov tungsten thiab qee cov OEM filaments rau cov tshuab hluav taws xob nrov, suav nrog:
• JEOL
• Leybold
• Telemark
• Temescal
• Thermionic
Peb txhawb kev hloov kho ntau yam lus qhia thiab cov duab. Thov hu rau peb yog tias tsim nyog.
Feem ntau cov ntim khoom yog ib lub thawv (10 daim), uas kuj yog MOQ tsawg kawg nkaus.
Cov ntawv thov
Cov filaments tungsten uas muaj hluav taws xob siv dav hauv ntau yam lag luam thiab cov teb xws li kev tsim khoom siv semiconductor, optics, aerospace thiab automotive. Nws yog siv los tso cov yeeb yaj kiab nyias nyias ntawm cov hlau, oxides thiab lwm yam khoom siv rau ntawm cov substrates rau cov ntawv thov xws li integrated circuits, optical coatings, solar cells thiab decorative topcoats.
