Tungsten Umuringa wa Alloy Rods
Ibisobanuro
Umuringa wa tungsten (CuW, WCu) wamenyekanye nkibikoresho bikora cyane kandi birwanya isuri bikoreshwa cyane nkumuringa wa tungsten electrode mu gutunganya imashini ya EDM no gusudira, guhuza amashanyarazi mumashanyarazi akoreshwa cyane, hamwe nubushyuhe hamwe nibindi bikoresho bipakira ibikoresho bya elegitoroniki. mu bushyashya.
Ikigereranyo cya tungsten / umuringa gikunze kugaragara ni WCu 70/30, WCu 75/25, na WCu 80/20.Ibindi bihimbano bisanzwe birimo tungsten / umuringa 50/50, 60/40, na 90/10.Urutonde rwibintu bihari ni kuva Cu 50 wt.% Kugeza Cu 90 wt.%.Ibicuruzwa byumuringa bya tungsten birimo umuringa wa tungsten, fayili, urupapuro, isahani, umuyoboro, inkoni y'umuringa, hamwe nibice byakozwe.

Ibiranga
Mugihe cyo gukora umuringa wa tungsten wumuringa, kanda cyane tungsten irakanda, ikayungurura hanyuma ikinjizwa numuringa utagira ogisijeni nyuma yintambwe yo guhuriza hamwe.Umuringa uhujwe na tungsten umuringa werekana microstructure ya homogeneous hamwe nurwego rwo hasi rwa porosity.Guhuza imiyoboro yumuringa hamwe nubucucike bukabije bwa tungsten, gukomera, hamwe no gushonga cyane bitanga umusaruro hamwe nibintu byinshi byingenzi bigize ibintu byombi.Umuringa winjiye muri tungsten urata ibintu nko kurwanya cyane ubushyuhe bwo hejuru hamwe na arc-isuri, ubwiza bwumuriro n’amashanyarazi hamwe na CTE yo hasi (coefficente yubushyuhe).
Imiterere yumubiri nubukanishi hamwe no gushonga ingingo yumuringa wa tungsten bizagira ingaruka nziza cyangwa zinyuranye no guhindura urugero rwumuringa wa tungsten muri compte.Kurugero, uko ibintu bikozwe mu muringa bigenda byiyongera buhoro buhoro, amashanyarazi nu mashanyarazi hamwe no kwagura ubushyuhe byerekana ubushake bwo gukomera.Nyamara, ubucucike, kurwanya amashanyarazi, gukomera n'imbaraga bizacika intege iyo byinjijwe n'umuringa muke.Kubwibyo, imiti ikwiye ningirakamaro cyane mugihe usuzumye umuringa wa tungsten kugirango ukoreshwe.
Kwiyongera k'ubushyuhe buke
Umuyoboro mwinshi w'amashanyarazi n'amashanyarazi
Kurwanya arc cyane
Gukoresha make
Porogaramu
Imikoreshereze yumuringa wa Tungsten (W-Cu) yiyongereye ku buryo bugaragara mu mirima myinshi no mu bikorwa bitewe n’imiterere yihariye ya mashini na thermofiziki.Ibikoresho by'umuringa bya Tungsten byerekana ibikorwa byiza cyane muburyo bwo gukomera, imbaraga, gutwara, ubushyuhe bwinshi, no kurwanya isuri.Yakoreshejwe cyane mugukora amashanyarazi, ibyuma bisohora ubushyuhe hamwe nogukwirakwiza, amashanyarazi ya EDM yica-amashanyarazi hamwe no gutera inshinge.
