Lanthanated tungsten Alloy Rod
Ibisobanuro
Lanthanated tungsten ni okiside ya lanthanum ikozwe mu bwoko bwa tungsten alloy, ishyirwa mu rwego rwa okisiside idasanzwe ya tungsten (W-REO).Iyo hongeweho okiside ya lanthanum yongeweho, tungsten ya lanthanate yerekana imbaraga zirwanya ubushyuhe, ubushyuhe bwumuriro, kurwanya ibinyabuzima, hamwe nubushyuhe bwo hejuru.Iyi mitungo idasanzwe ifasha langanated tungsten electrode kugera kubikorwa bidasanzwe mubushobozi bwo gutangira arc, kurwanya isuri, hamwe no guhagarara kwa arc no kugenzura.
Ibyiza
Ntibisanzwe isi ya okiside ikoreshwa na tungsten electrode, nka W-La2O3 na W-CeO2, ifite ibintu byinshi byo gusudira.Ntibisanzwe isi ya oxyde doped tungsten electrode yerekana ibintu byiza muri electrode ya Gas Tungsten Arc Welding (GTAW), izwi kandi gusudira Tungsten Inert Gas (TIG) hamwe na Plasma Arc Welding (PAW).Okiside yongewe kuri tungsten yongereye ubushyuhe bwa recrystallisation kandi, icyarimwe, yazamuye urwego rwohereza imyuka mu kugabanya imikorere ya electron ya tungsten

Ibiranga
Ibicuruzwa byacu byitwa tungsten birimo WLa10 (La2O3 1-1.2 wt.%), WLa15 (La2O3 1.5-1.7 wt.%), Na WLa20 (La2O3 2.0-2.3 wt.%). ibipimo ngenderwaho bya porogaramu zitandukanye.Dutanga amashanyarazi ya tungsten electrode yo gusudira Tungsten Inert Gas (TIG), gusudira kwihanganira, no gutera plasma.Dutanga kandi diameter nini ya WLa kugirango ikoreshwe mubice bya semiconductor hamwe nitanura ryubushyuhe bwo hejuru.
Porogaramu
WLa TIG gusudira electrode byoroshye arc yatangijwe kandi iramba cyane.WLa plasma spray electrode yerekana guhangana cyane nisuri ya arc nubushyuhe bwo hejuru kandi ifite ubushyuhe burenze.WLa irwanya gusudira electrode ifite aho ishonga kandi itanga imikorere ihamye.
