Ihame ryo gutwika vacuum
1 、 Ibikoresho hamwe nuburyo bufatika bwo guhumeka
Ibikoresho byo gutwika vacuum bigizwe ahanini na chambre vacuum na sisitemu yo kwimuka.Imbere mu cyumba cya vacuum, hari isoko yo guhumeka (ni ukuvuga umushyushya wa evaporation), substrate na substrate frame, substrate heater, sisitemu yo gusohora, nibindi.
Ibikoresho bitwikiriye bishyirwa mumasoko yumubyuka wicyumba cya vacuum, kandi mugihe cyimyuka myinshi, ashyutswe nisoko ryuka kugirango bivemo.Iyo impuzandengo yubusa ya molekile ziva mumyuka nini kuruta ubunini bwumurongo wa chambre vacuum, nyuma ya atome na molekile zumuyaga wa firime zimaze guhunga hejuru yisoko ryuka, ntibikunze kubangamirwa no kugongana kwizindi molekile cyangwa atome, hanyuma uhite ugera hejuru ya substrate kugirango itwikwe.Bitewe n'ubushyuhe buke bwa substrate, uduce twa firime ya vapor yegeranye kandi ikora firime.
Kugirango tunonosore ifatanyirizo rya molekile ziva hamwe na substrate, substrate irashobora gukoreshwa no gushyushya neza cyangwa gusukura ion.Vacuum evaporation coating inyura mubikorwa bikurikira biva kumubiri, gutwara ibintu kugeza muri firime.

(3) Ibice bya gaze bigera hejuru yubutaka bwa substrate coalesce na nucleate, hanyuma bigakura bigahinduka firime ikomeye.
(4) Kuvugurura cyangwa guhuza imiti ya atome zigize firime.
Gushyushya umwuka
(1) Kurwanya ubushyuhe buguruka
Imyuka yo gushyushya imyuka nuburyo bworoshye kandi bukoreshwa cyane mubushuhe, mubisanzwe bikoreshwa mubikoresho byo gutwika bifite aho bishonga biri munsi ya 1500 ℃, ibyuma byo gushonga hejuru mubyuma cyangwa kumpapuro (W, Mo, Ti, Ta, nitride ya boron, nibindi) ni mubisanzwe bikozwe muburyo bukwiye bwo guhumeka, byuzuyemo ibikoresho byo guhumeka, binyuze mubushyuhe bwa Joule bwumuyagankuba kugirango ushonge, uhumeke cyangwa ugabanye ibikoresho bya plaque, imiterere yinkomoko yumuyaga ahanini ikubiyemo imirongo myinshi, U-shusho, sine wave Isahani yoroheje, ubwato, igitebo cya cone, nibindi. Muri icyo gihe, uburyo busaba ibikoresho biva mu kirere kugira aho bishonga cyane, umuvuduko ukabije w’umwuka wumuyaga, imiterere yimiti ihamye, ntigire imiti yimiti hamwe nubushyuhe hejuru yubushyuhe bwinshi, ubushyuhe bwiza bwo guhangana nubushyuhe, impinduka ntoya mubucucike bwamashanyarazi, nibindi. Ifata umuyaga mwinshi binyuze mumasoko yumwuka kugirango ushushe kandi uhindurwe nibikoresho bya firime ukoresheje ubushyuhe butaziguye, cyangwa ugashyira ibikoresho bya firime mubikomeye bikozwe muri grafite hamwe nubushyuhe bwo hejuru cyane okiside yicyuma (nka A202, B0) nibindi bikoresho byo gushyushya butaziguye kugirango bishire.
Kurwanya ubushyuhe bwo guhumeka bifite aho bigarukira: ibyuma bitavunika bifite umuvuduko muke wumuyaga, bigoye gukora firime yoroheje;ibintu bimwe byoroshye gukora umusemburo hamwe ninsinga zishyushya;ntabwo byoroshye kubona ibice bimwe bya firime ya alloy.Kubera imiterere yoroshye, igiciro gito nigikorwa cyoroshye cyo kurwanya ubushyuhe bwo guhumeka, ni uburyo bukoreshwa muburyo bwo guhumeka.
(2) Imashanyarazi ya elegitoronike
Impumuro ya elegitoronike ni uburyo bwo guhumeka ibikoresho byo gutwikisha ibisasu ukoresheje ingufu za elegitoronike zifite ingufu nyinshi ubishyira mu muringa ukonje w’amazi.Inkomoko yo guhumeka igizwe nisoko yohereza ibyuka bya elegitoronike, isoko yihuta yihuta ya electron, ikintu gikomeye (mubisanzwe umuringa umuringa), agapira ka magnetiki, hamwe namazi akonje, nibindi. Muri iki gikoresho, ibikoresho bishyushye bishyirwa mumazi -ibikonje bikonje, hamwe na bombo ya electron ibisasu igice gito cyane cyibikoresho, mugihe ibyinshi mubisigaye biguma ku bushyuhe buke cyane bitewe ningaruka zo gukonjesha umusaraba, ushobora gufatwa nkigice cyatewe ibisasu byingenzi.Rero, uburyo bwo gushyushya imashanyarazi ya elegitoronike yo guhumeka bishobora kwirinda kwanduza ibintu bitwikiriye hamwe n’ibikoresho biva mu kirere.
Imiterere yinkomoko ya elegitoroniki yumuriro irashobora kugabanywamo ubwoko butatu: imbunda igororotse (imbunda ya Boules), imbunda zimpeta (zashizwe mumashanyarazi) na e-mbunda (magnetique).Ikintu kimwe cyangwa byinshi byingenzi bishobora gushyirwa mumashanyarazi, bishobora guhumeka no kubitsa ibintu byinshi icyarimwe cyangwa bitandukanye.
Amashanyarazi ya elegitoroniki yamashanyarazi afite ibyiza bikurikira.
DensityUbucucike bwinshi bwibikoresho bya elegitoroniki y’ibisasu biva mu kirere bishobora kubona ingufu nyinshi cyane kuruta isoko yo gushyushya ibintu, ishobora guhumeka ibikoresho byo hejuru bishonga, nka W, Mo, Al2O3, nibindi ..
MaterialIbikoresho byo gutwikira bishyirwa mu muringa ukonjeshejwe n'umuringa ukonje, ushobora kwirinda guhumuka kw'ibikoresho biva mu kirere, hamwe n'ibisubizo hagati yabo.
EUbushyuhe burashobora kongerwamo neza hejuru yububiko bwibikoresho, bigatuma ubushyuhe bwumuriro buri hejuru no gutakaza ubushyuhe bwumuriro nubushyuhe buke.
Ikibi cyuburyo bwa elegitoronike yo gushyushya ibyuka ni uko electron zambere ziva mu mbunda ya electron na electroni ya kabiri zivuye hejuru yibikoresho bitwikiriye bizahindura ioni za atome zigenda ziyongera hamwe na molekile ya gaze isigaye, ibyo bizagira ingaruka kumiterere ya firime rimwe na rimwe.
(3) Umuvuduko mwinshi wo kwinjiza ubushyuhe buguruka
Guhindura ubushyuhe bwumuriro mwinshi ni ugushira ingirakamaro hamwe nibikoresho byo gutwikiriye hagati ya coil-spiral coil, kugirango ibikoresho bitwikire bibyara imbaraga zikomeye za eddy hamwe na hystereze munsi yo kwinjiza umurima wa electromagnetic yumuriro mwinshi, utera firime ya firime kugirango ishyushye kugeza ihumutse kandi igashiramo.Inkomoko yo guhumeka muri rusange igizwe na coil ikonjesha amazi menshi hamwe na grafite cyangwa ceramic (oxyde ya magnesium, oxyde ya aluminium, oxyde ya boron, nibindi) ikomeye.Amashanyarazi maremare menshi akoresha inshuro ibihumbi icumi kugeza ku bihumbi magana Hz, ingufu zinjiza ni kilowat nyinshi kugeza kuri magana, uko ingano y'ibikoresho bya membrane, niko inshuro nyinshi yinjira.Induction coil inshuro nyinshi ikozwe mumazi akonje y'amazi.
Ingaruka zuburyo bwinshi bwo kwinjiza ubushyuhe bwo guhumeka ni uko bitoroshye guhindura neza imbaraga zinjiza, bifite ibyiza bikurikira.
Rate Igipimo kinini cyo guhumeka
TemperatureUbushyuhe buturuka kumyuka ni kimwe kandi gihamye, ntabwo rero byoroshye kubyara ibintu byo gutwika ibitonyanga, kandi birashobora no kwirinda ibintu bya pinholes kuri firime yabitswe.
Inkomoko yo guhumeka yapimwe rimwe, kandi ubushyuhe buroroshye kandi bworoshye kugenzura.
