Ngocingo lweTungsten oluXiniweyo lweVacuum Metalling

Inkcazelo emfutshane:

Izikhephe ze-tungsten, iibhaskithi kunye neefilaments zenziwe kwi-tungsten yomgangatho ophezulu.Kuzo zonke iintsimbi ezikwimo ecocekileyo, i-tungsten ineyona ndawo iphezulu yokunyibilika (3422 ° C / 6192 ° F), olona xinzelelo lomphunga luphantsi kumaqondo obushushu angaphezu kwe-1650 ° C (3000 ° F) kwaye inamandla aphezulu okubamba.I-Tungsten ikwanayo neyona coefficient isezantsi yokwandiswa kwe-thermal yayo nayiphi na intsimbi ecocekileyo.Le ndibaniselwano yeepropathi yenza i-tungsten ibe yeyona nto ifanelekileyo kwimithombo yobushushu.Ngexesha lokuvela komphunga, inokuba nengxubevange ngezinye izinto ezifana ne-Al okanye i-Au.Kule meko, enye imathiriyeli yomthombo womoya kufuneka isetyenziswe njengezikhephe ezigqunywe nge-alumina okanye iibhaskithi.Ezinye izinto eziluncedo kwimithombo yobushushu yi molybdenum kunye ne tantalum.
