Cov yam ntxwv ntawm cu - W ua rau nws yog cov khoom siv hluav taws xob zoo tshaj plaws rau hluav taws xob hluav taws xob

Thaum koj xav txog EDM cov khoom siv electrode, tej zaum koj yuav xav txog graphite. Pib thaum xyoo 1950, thaum cov khoom siv thawj zaug dej nyab lub lag luam electrode, thiab txuas ntxiv mus rau hnub no, graphite tseem yog cov khoom xaiv rau 90% ntawm US edM electrode daim ntaub ntawv. Tab sis li cas txog lwm 10%?

Ntev ua ntej graphite, muaj hlau. Ntawm ntau yam khoom siv electrode rau hlau edM, tooj liab thiab tungsten yog thawj qhov kev xaiv ntawm ntau lub tuam txhab. Kev sib xyaw tshwj xeeb ntawm cov khoom siv uas ua los ntawm tooj liab thiab tungsten alloying yog qhov zoo rau kev tso tawm machining carbides, qhov twg hluav taws xob tsis kam thiab txiav kev ruaj ntseg yog qhov tseem ceeb.

Yog li, thaum graphite dominates qhov dav ntawm cov khoom siv electrode rau EDM, tooj liab tungsten muaj qhov chaw ruaj khov raws li cov khoom ntawm kev xaiv rau complex geometry, cov kaum ntse ntse, zoo heev hnav tsis kam thiab txiav ceev.

Yog xav paub ntxiv txog cov khoom ntawm tooj liab thiab tungsten, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov hluav taws xob hluav taws xob.
