Tungsten ifite gushonga hejuru yibyuma byose kimwe na modulus yo hejuru idasanzwe. Bitewe nubushyuhe bwihariye bwumuriro, tungsten irashobora kwihanganira byoroshye nubushyuhe bwo hejuru. Tungsten nayo igaragara cyane kubera ubwinshi bwayo bityo ikaba ikoreshwa muburyo butandukanye bukoreshwa mu nganda nko mu nganda z’indege n’ikirere, inganda z’amashanyarazi, ndetse n’ikoranabuhanga.
Porogaramu yibanze ya Tungsten mumyaka irenga 100 yabaye nka filament mumatara yaka. Ifumbire hamwe na silikatike ya potasiyumu-aluminiyumu, ifu ya tungsten yungururwa ku bushyuhe bwo hejuru kugira ngo itange insinga ya wire iri hagati y’itara rimurikira amazu miriyoni ku isi.
Bitewe nubushobozi bwa tungsten bwo kugumana imiterere yubushyuhe bwinshi, ubu tungsten filaments nayo ikoreshwa mubikoresho bitandukanye byo murugo, birimo amatara, amatara yumwuzure, ibintu bishyushya mumatanura yumuriro, microwave, hamwe nigituba cya x-ray.
Kwihanganira icyuma kubushyuhe bukabije nabwo bituma biba byiza kuri thermocouples no guhuza amashanyarazi mumatanura ya arc nibikoresho byo gusudira. Porogaramu isaba misa yibanze, cyangwa uburemere, nkibiremereye, ubwato bwo kuroba, hamwe n imyambi akenshi ikoresha tungsten kubera ubwinshi bwayo.
Hamwe nubuziranenge bwa> 99,98%, burakoreshwa cyane mubice byo guteramo igice cya semiconductor ion, ibintu byo gushyushya, intego za sputter, electrode, ibice byubushyuhe bwo hejuru, ibice bya kristu, kubirwanya, gukingira imirasire, gukwirakwiza ingufu zamashanyarazi nibindi bihe.
Dutanga ibicuruzwa bya tungsten kuva ifu yicyuma kugeza kubicuruzwa byarangiye. Dukoresha gusa okiside ya tungsten isukuye nkibikoresho nkomoko. Dutanga ibicuruzwa byiza bya tungsten bifite isuku igera kuri 8N.
okiside yisi idasanzwe tungsten (W-REO)
Oxidized isi idasanzwe ya tungsten (WLa, WCe, WTh, WY hamwe nandi mavuta adasanzwe yisi) ifite imbaraga nyinshi nigikorwa cyihariye cyo gusohora kurusha tungsten yera, kandi ikoreshwa cyane muri electrode zitandukanye: gusudira TIG, gusudira plasma, gusudira plasma, gutwikira plasma, gushonga plasma no gusohora gaz isoko yumucyo; ikoreshwa kandi mubice byubushyuhe bwo hejuru.
Lanthanated tungsten ni okiside ya lanthanum ikoporora tungsten. 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.
Dufite ubushobozi bwo gukora W-La, W-Ce, WY, W-Th hamwe nubundi buryo bwa okiside bwisi budasanzwe tungsten. Bakoreshwa cyane nka electrode na cathodes mubisabwa byinshi. Okiside yongewe kuri tungsten yongereye ubushyuhe bwa recrystallisation kandi, icyarimwe, yazamuye urwego rwoherezwa mu kirere igabanya imikorere ya electron ya tungsten electrode.
Potasiyumu-yuzuye Tungsten (Tungsten - potasiyumu cyangwa WK)
Potasiyumu (K) -yuzuye W irimo nano-bubbles kuri gahunda ya ppm irashobora kubangamira urujya n'uruza rwimbibi no kwimurwa, biganisha ku gukomera ku bushyuhe bwinshi no guhagarika rerystallisation kandi bishobora gutanga ibinyampeke byiza ugereranije na W. Yera gutunganya nabyo biganisha ku gushimangira no gukomera. Byongeye kandi, biteganijwe ko insimburangingo ya neutron-irrasiyoya ishobora guhagarikwa muri K-dope W ugereranije na W yera kuko irimo imbibi nyinshi zimbibi zikora nkibimera kubera inenge zatewe na irrasi ya neutron.
Tungsten (W) ifatwa nkumwe mubakandida bafite ibyiringiro byinshi mubikoresho bireba plasma (PFMs) kubera imiterere yihariye, nko kugumana hydrogène nkeya ya isotope, umusaruro muke ndetse no gushonga cyane. Nubwo bimeze bityo ariko, ibibi, nkubushyuhe bwo hejuru bwihuta (DBTT), ubukana bwubushyuhe buke nubushuhe kubera imishwarara ya neutron ni inzitizi zibangamira ikoreshwa rya tungsten. Igishushanyo cya W-ishingiye ku mavuta hamwe na dopant ductile ni uburyo bwiza bwo kugabanya izo ngaruka. Doping ya Potasiyumu yamaze kwerekana ko ikora neza muguhagarika iyongera rya kabiri no kugenzura imikurire y’ingano kugeza kuri 1900 ° C mu nsinga zoroshye, bityo ikerekana ibintu bidasanzwe ku bushyuhe bwo hejuru. Potasiyumu-yuzuye (K-doped) tungsten ibintu byinshi biba umukandida ushimishije kubintu bisa na plasma. Byatangajwe ko K-doped tungsten yahimbwe na plasma sintera (SPS) yerekana ubushyuhe bwiza bwumuriro, hamwe nubukanishi bukomeye mubushyuhe kuva kuri RT kugeza kuri 50 ° C.
