Tungsten electrodesFeem ntau siv rau hauv tungsten inert gas (TIG) vuam thiab plasma txiav txheej txheem.Hauv TIG welding, tungsten electrode yog siv los tsim ib qho arc, uas tsim cov cua sov uas xav tau los yaj cov hlau uas tau welded.Electrodes kuj ua raws li cov neeg siv hluav taws xob rau cov hluav taws xob tam sim no siv thaum vuam.Tungsten electrodes feem ntau nyiam rau lawv lub peev xwm tiv taus qhov kub thiab txias thiab muab cov yam ntxwv ruaj khov, ua rau lawv haum rau ntau yam kev siv vuam.

Tungsten yog dav siv nyob rau hauv ntau yam kev siv nyob rau hauv electronics kev lag luam.Nws yog feem ntau siv los tsim hluav taws xob emitters thiab cathodes rau cov khoom siv hluav taws xob xws li lub tshuab nqus tsev, cov phom hluav taws xob, thiab X-ray raj.Tungsten lub siab melting point thiab zoo thermal thiab hluav taws xob conductivity ua rau nws haum rau cov kev siv.Tsis tas li ntawd, tungsten thiab nws cov tebchaw yog siv los tsim cov hluav taws xob tiv tauj, cov khoom cua sov thiab cov khoom siv hluav taws xob vim lawv qhov kub thiab txias tsis kam thiab cov khoom hluav taws xob zoo heev.Zuag qhia tag nrho, tungsten plays lub luag haujlwm tseem ceeb hauv kev lag luam hluav taws xob, pab txhim kho kev ua haujlwm thiab kev ntseeg siab ntawm ntau yam khoom siv hluav taws xob.

Tungsten electrodesfeem ntau yog tsim los siv cov txheej txheem hmoov metallurgy.Ntawm no yog cov txheej txheem dav dav ntawm cov txheej txheem: hmoov ntau lawm: tungsten hmoov yog pib tsim los ntawm kev txo qis, feem ntau muaj tungsten oxide.Qhov tshwm sim yog nplua tungsten hmoov.Kev sib xyaw hmoov: tungsten hmoov tuaj yeem sib xyaw nrog lwm cov ntsiab lus lossis cov alloys, xws li thorium, cerium lossis lanthanum, txhawm rau txhim kho nws cov kev ua tau zoo li electrode.Cov alloys no txhim kho cov hluav taws xob emission, arcing thiab stability ntawm electrode.Nias: Cov hmoov sib xyaw ces nias rau hauv cov duab uas xav tau los ntawm kev sib xyaw ua ke ntawm cov siab thiab cov nplaum.Cov txheej txheem no, hu ua compaction, tsim cov duab nias ntawm electrode.Sintering: Compacted tungsten hmoov yog sintered nyob rau hauv lub qhov cub kub.Thaum lub sij hawm sintering txheej txheem, cov hmoov cov khoom sib txuas ua ke los tsim kom muaj zog, ntom ntom tungsten electrode nrog cov khoom xav tau thiab cov duab.Kev Ua tiav: Sintered electrodes tuaj yeem ua tiav ntxiv, xws li kev sib tsoo, machining lossis polishing, kom ua tiav qhov kawg qhov ntev, nto tiav thiab geometric raug xav tau rau lawv daim ntawv thov tshwj xeeb.Zuag qhia tag nrho, kev tsim cov tungsten electrodes muaj kev sib xyaw ua ke ntawm cov hmoov ntau lawm, sib tov, nias, sintering thiab ua tiav cov txheej txheem los tsim cov khoom siv hluav taws xob zoo rau ntau yam kev lag luam thiab kev lag luam.
