PVD Vacuum Txheej Tshuab

Tungsten hlau yog ib qho khoom siv tseem ceeb hauv lub tshuab nqus tsev. Cia peb tham txog kev siv cov khoom siv no thiab kev ceev faj rau kev siv.

Daim ntawv thov ntawm tungsten hlau nyob rau hauv lub tshuab nqus tsev txheej:

Tsuas yog qee qhov me me ntawm tungsten hlau siv los ua cov khoom siv cua sov rau cov cua kub kub, cov cua sov ntawm cov raj hluav taws xob thiab cov khoom siv hluav taws xob ntxiv, feem ntau ntawm cov xov hlau tungsten yog siv los ua filaments ntawm ntau yam dawb tungsten incandescent teeb thiab tungsten halogen teeb. thiab roj tso tawm teeb. electrode. Rau cov tungsten hlau lossis tungsten pas nrig siv los ua lub cathode ntawm cov roj tso tawm teeb, txhawm rau txo nws txoj haujlwm electron, 0 5-3 feem pua ​​thorium yuav tsum tau ntxiv, uas yog hu ua tungsten-thorium hlau. Txij li thaum thorium yog cov khoom siv hluav taws xob uas ua rau ib puag ncig, cerium yog siv los hloov thorium los ua tungsten-cerium hlau lossis tungsten-cerium qws. Tab sis tus nqi evaporation ntawm cerium yog siab, yog li tungsten cerium hlau los yog tungsten cerium qws tsuas yog siv tau rau cov hluav taws xob qis hluav taws xob.
