Kurwanya ubushyuhe buguruka inkomoko yimiterere iroroshye, yoroshye kuyikoresha, yoroshye kuyikora, niyo ikoreshwa cyane muburyo bumwe bwo guhumeka. Abantu bakunze kwitwa amashanyarazi cyangwa ubwato buguruka.
Gushyushya ibisabwa mubikoresho byo kurwanya byakoreshejwe ni: ubushyuhe bwinshi, kwihanganira, umuvuduko muke wumuyaga mwinshi, nta reaction yimiti hamwe nibikoresho bya membrane, ntibitanga ibyangiza no guhumana. Ibikoresho byatoranijwe byo gushyushya ibikoresho biva mubyuma byangiritse, nka W, Mo, Ta nibindi bikoresho cyangwa guhitamo isuku ryinshi, grafite imbaraga nyinshi cyangwa borit nitride ya synthique yubukorikori nibindi bikoresho. Rimwe na rimwe, irashobora kandi guhitamo Fe, Ni, Ni-Cr alloy na Pt nkibikoresho byo guhumeka.
Inkomoko zitandukanye zo guhangana nubushyuhe bwibikoresho bisanzwe (nka Ti, Mo, C, Ta, W, nibindi) byumwanya wo gushonga hamwe numuvuduko wumuyaga hamwe nubushuhe bwubushuhe buratandukanye. Muri byo, tungsten iba yoroheje iyo ishyutswe nubushyuhe bwo guhumeka kubera ibicuruzwa bishyushya. Ku rundi ruhande, Molybdenum iratandukanye mu kweza, bamwe bakavunika abandi ntibabe. Tungsten ifata imyuka y'amazi kugirango ikore umwuka wa ogisijeni uhindagurika WO3.
Kubwibyo, iyo tungsten ishyutswe mumazi asigaye, ibintu bishyushye bikomeza kugabanuka. Iyo umuvuduko wa gaze usigaye ari muke, nta gutakaza ibintu byinshi, ariko ni umwanda ukomeye wa membrane.
Gukoresha amasoko ya filime bigomba kwitondera guhanagura insinga zishyushye kubintu bya membrane. Kurugero, ubushyuhe bwinsinga zishyushye kuzamuka vuba, ibikoresho bya membrane ntabwo byoroshye guhita bishonga ibintu byose bya membrane kandi guhanagura insinga zishyushye ntibihagije. Nkigisubizo, firime idashonga irashobora kugwa mubiseke. Mugihe kimwe, izamuka ryubushyuhe ryihuta cyane bizanatera ibintu bya membrane muri gaze irekuwe vuba, bikavamo ibibyimba cyangwa kumeneka, ibisubizo bizatuma habaho udutonyanga duto twizirika kuri substrate. Kubwibyo, isoko ya filament igomba gukoreshwa hamwe no kugenzura ubushyuhe.
Ingaruka nyamukuru yibitebo byinsinga, coil coil cyangwa coil spiral ni uko umubare wibikoresho bya firime ushyigikiwe ari muto cyane, kandi iyi soko izatera ubushyuhe bwinsinga zishyushye kwiyongera kuko umubare wibikoresho bya firime ugabanuka nyuma yibikoresho bya firime bimaze guhumeka, bityo bigatuma igipimo cyuka kizamuka. Iki kandi nikibazo gikwiye kwitonderwa mubikorwa byo gukora firime bisaba kugenzura neza igipimo cyuka.
(2) Ihame ryakazi nimiterere yimiterere no gukoresha ibiranga
Inkomoko yo gushyushya ibyuka, mubyukuri, ni ubushyuhe bwo kurwanya ni ugukoresha amashanyarazi cyangwa ubwato buguruka bugashyiramo ingufu mu buryo butaziguye, ku buryo umuyoboro unyuze mu mubare munini wa Joule ukabona ubushyuhe bwinshi bwo gushonga ibyuma bya firime, ku buryo bigenda bihinduka ubwoko bw’isoko.
