Tungsten Electrode yo gusudira TIG
Mu buso bunini bwa siyansi ninganda zigezweho, ubwato bwa tungsten bugaragara nkigikoresho kidasanzwe gifite ibikorwa bitandukanye kandi byingenzi.
Ubwato bwa Tungsten bukozwe muri tungsten, icyuma kizwiho imiterere yihariye. Tungsten ifite aho ishonga cyane bidasanzwe, itwarwa neza nubushyuhe, hamwe no kurwanya imiti idasanzwe. Iyi mico ituma iba ibikoresho byiza byo gukora imiyoboro ishobora kwihanganira ibihe bikabije.
Imwe muma progaramu yibanze yubwato bwa tungsten ni murwego rwo guta vacuum. Hano, ubwato bwashyutswe n'ubushyuhe bwinshi mucyumba cya vacuum. Ibikoresho byashyizwe mubwato bicika kandi bigashyirwa kuri substrate, bigakora firime yoroheje ifite ubunini bwuzuye nibigize. Iyi nzira ningirakamaro mugukora semiconductor. Kurugero, mugukora microchips, ubwato bwa tungsten bufasha kubitsa ibice byibikoresho nka silikoni nicyuma, bigakora uruziga rukomeye rutanga isi yacu ya digitale.
Mu rwego rwa optique, ubwato bwa tungsten bugira uruhare runini. Bakoreshwa mukubika ibifuniko ku ndorerwamo no mu ndorerwamo, bikongerera imbaraga no kwanduza. Ibi biganisha ku kunoza imikorere mubikoresho bya optique nka kamera, telesikopi, na sisitemu ya laser.
Inganda zo mu kirere nazo zungukirwa nubwato bwa tungsten. Ibigize guhura nubushyuhe bwinshi nibidukikije bikaze mugihe cyurugendo rwo mu kirere bihimbwa ukoresheje ububiko bwagenzuwe bworoherezwa nubwato. Ibikoresho byashyizwe muri ubu buryo bitanga ubushyuhe burenze kandi burambye.
Ubwato bwa Tungsten nabwo bukoreshwa mugutezimbere ibikoresho bishya byo kubika ingufu no guhindura. Bafasha muguhuza no kuranga ibikoresho bya bateri na selile, bigatuma bashakisha ibisubizo byiza kandi birambye.
Mubushakashatsi bwa siyanse yibintu, bashoboza kwiga ibyiciro byinzibacyuho hamwe nimiterere yibintu mugihe cyuka kiguruka. Ibi bifasha abahanga gusobanukirwa no gukoresha imyitwarire yibikoresho kurwego rwa atome.
Byongeye kandi, mugukora ibicuruzwa byabugenewe bikoreshwa mubikorwa bitandukanye byinganda, ubwato bwa tungsten butuma ikoreshwa ryibikoresho bimwe kandi neza, bikongerera imikorere no kuramba hejuru yubuso.
Ubwato bwa tungsten ni ikintu cy'ingenzi mu ikoranabuhanga rigezweho. Ubushobozi bwayo bwo koroshya ibintu bigenzurwa no guhumeka bituma bigira uruhare runini rwiterambere ryiterambere mubice byinshi, bigahindura ejo hazaza ha siyanse ninganda.
Ibicuruzwa bisanzwe
Dukora ubwato buguruka bukozwe muri molybdenum, tungsten, na tantalum kugirango ubisabe:
Amato ya Tungsten
Tungsten irwanya ruswa cyane ugereranije n’ibyuma byinshi bishongeshejwe, hamwe n’ahantu hahanamye cyane mu byuma byose, irwanya ubushyuhe bukabije. Dukora ibikoresho ndetse birwanya ruswa kandi bigahagarara neza dukoresheje dopants idasanzwe nka silikasi ya potasiyumu.
Ubwato bwa Molybdenum
Molybdenum nicyuma gihamye cyane kandi irakwiriye nubushyuhe bwo hejuru. Dopi hamwe na okiside ya lanthanum (ML), molybdenum irarushijeho guhinduka kandi irwanya ruswa. Twongeyeho okiside yttrium (MY) kugirango tunoze imikorere ya molybdenum
Amato ya Tantalum
Tantalum ifite umuvuduko muke cyane wumuvuduko numuvuduko muke. Igitangaje cyane kuri ibi bikoresho, ariko, ni ukurwanya kwangirika kwinshi.
Cerium-Tungsten Electrode
Cerium-Tungsten Electrode ifite imikorere myiza yo gutangira arc kumiterere ya crrrent yo hasi. Umuyoboro wa arc ni muto, kubwibyo electrode irashobora gukoreshwa mugusudira imiyoboro, idafite ingese nibice byiza. Cerium-Tungsten niyo ihitamo ryambere ryo gusimbuza Thoriated Tungsten muburyo bwa DC yo hasi.

Amashanyarazi ya Tungsten Electrode
Tungsten ya lanthanated yamenyekanye cyane muruziga rwo gusudira kwisi nyuma gato yuko itezwa imbere kubera imikorere myiza yo gusudira. Amashanyarazi ya tungsten yamashanyarazi arafunzwe cyane kuri 2% ya Tungsten. Abasudira barashobora gusimbuza byoroshye tungsten tungsten Electrode hamwe na tungsten electrode ya lanthanated kuri AC cyangwa DC kandi ntibagomba guhindura gahunda yo gusudira. Iradiyo ituruka kuri thoriated tungsten irashobora kwirindwa. Iyindi nyungu ya tungsten ya lanthanate ni ugushobora kwihanganira umuyaga mwinshi kandi ufite igipimo gito cyo gutwika.

Zirconiated Tungsten Electrode
Zirconiated tungsten ifite imikorere myiza muri welding ya AC, cyane cyane munsi yumutwaro mwinshi. Izindi electrode zose ukurikije imikorere yazo nziza ntishobora gusimbuza Zirconiated tungsten electrode. Electrode igumana impera yumupira mugihe cyo gusudira, bigatuma habaho tungsten nkeya no kurwanya ruswa.
Abakozi bacu ba tekinike bakoze imirimo yubushakashatsi no kugerageza kandi bashoboye gukemura amakimbirane hagati ya zirconium nibintu bitunganyirizwa.
