Hauv kev tsim khoom thiab kev tsim cov khoom siv, cov txheej txheem nqus cov txheej txheem sawv tawm raws li cov thev naus laus zis tseem ceeb uas tau hloov pauv ntau yam kev lag luam. Qhov kev siv thev naus laus zis no tso cai rau cov yeeb yaj kiab nyias tuaj yeem siv rau ntau qhov chaw, muab cov khoom zoo dua qub thiab ua haujlwm zoo. Hauv cov ntawv blog no, peb siv qhov tob tob rau hauv cov txheej txheem nqus tsev, sib tham txog nws cov ntsiab lus tseem ceeb thiab qhia txog qhov nws ua lub luag haujlwm tseem ceeb hauv kev tsim khoom niaj hnub no.
Lub tshuab nqus tsev txheej txheej txheem yog dab tsi?
Nqus txheej yog ib txoj hauv kev tso cov txheej nyias nyias ntawm cov khoom mus rau hauv lub substrate nyob rau hauv ib puag ncig tswj. Cov txheej txheem yuav siv qhov chaw nyob rau hauv lub tshuab nqus tsev chamber thiab siv ntau txoj kev xws li thermal evaporation, sputtering thiab electron beam deposition los siv cov khoom xav tau rau saum npoo. Los ntawm kev tshem tawm cov huab cua thiab lwm yam kab mob, cov txheej txheem nqus cov txheej txheem ua kom cov txheej txheem zoo, cov txheej txheem zoo sib xws uas ua raws li cov txheej txheem hauv qab.
Kev siv thiab qhov zoo ntawm lub tshuab nqus tsev vacuum:
Kev siv lub tshuab nqus tsev yog dav thiab ntau yam, nrog rau kev lag luam xws li tsheb, hluav taws xob, optics thiab txawm tias cov khoom siv hauv tsev tau txais txiaj ntsig los ntawm cov thev naus laus zis no. Piv txwv li, cov khaubncaws sab nraud povtseg uas siv los ntawm lub tshuab nqus tsev tuaj yeem muab kev txhim kho corrosion, abrasion tsis kam thiab kho qhov muag, ua rau cov khoom siv ruaj khov thiab zoo nkauj. Tsis tas li ntawd, nws tuaj yeem tso cov txheej txheem tshwj xeeb xws li cov tshuaj tiv thaiv kev cuam tshuam ntawm cov lo ntsiab muag, cov txheej txheem ntawm cov iav thiab cov txheej tiv thaiv ntawm cov hnub ci.
Txhim khu kev ua tau zoo thiab kev ua haujlwm:
Lub tshuab nqus tsev txheej txheej pab txhawb kev tso tawm ntawm ntau yam ntaub ntawv, suav nrog hlau, ceramics, semiconductors, thiab polymers. Los ntawm kev ua tib zoo xaiv thiab muab cov ntaub ntawv no, cov neeg tsim khoom tuaj yeem kho cov khoom ntawm coated substrates kom tau raws li cov kev xav tau tshwj xeeb. Lub tshuab nqus tsev coated cov khoom tuaj yeem nthuav tawm cov khoom siv hluav taws xob zoo, rwb thaiv tsev, cov khoom sib nqus, cov khoom siv kho qhov muag, thiab txawm tias biocompatibility. Qhov kev muaj peev xwm los txhim kho kev ua tau zoo thiab kev ua haujlwm tau ua rau lub tshuab nqus tsev vacuum yog ib qho cuab yeej siv tsis tau thoob plaws ntau qhov kev lag luam.
Kev vam meej thiab yav tom ntej tiam:
Tsav los ntawm kev hloov tshiab tas li, cov txheej txheem nqus cov txheej txheem txuas ntxiv txhim kho, thiab cov thev naus laus zis tshiab thiab cov ntaub ntawv tau tsim tawm tas li. Piv txwv li, pulsed laser deposition (PLD) thiab atomic layer deposition (ALD) sawv cev rau cov thev naus laus zis tshiab uas tso cai rau kev txiav txim siab ntau dua thiab tswj cov txheej txheem txheej. Tsis tas li ntawd, peb siv zog los txhim kho ib puag ncig tus phooj ywg thiab cov ntaub ntawv txheej txheem kom tau raws li qhov xav tau loj zuj zus ntxiv rau kev tsim khoom zoo ib puag ncig.
nyob rau hauv xaus:
Cov txheej txheem nqus tsev vacuum tau hloov pauv ntau yam kev lag luam los ntawm kev ua kom daim ntawv thov ntawm cov yeeb yaj kiab nyias nrog cov khoom zoo thiab kev ua haujlwm. Los ntawm kev ua kom muaj zog ntawm cov khoom siv tsheb mus rau kev txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob, cov tshuab nqus tsev ua lub luag haujlwm tseem ceeb hauv kev tsim khoom niaj hnub. Qhov cuam tshuam ntawm cov txheej txheem no tsuas yog nthuav dav raws li kev siv thev naus laus zis thiab cov ntaub ntawv tshiab tau tshawb pom, tsav tsheb tshiab thiab thawb cov ciam teb ntawm qhov ua tau hauv cov khoom siv engineering.
