Hauv kev siv tshuab niaj hnub no uas hloov zuj zus, cov txheej txheem kho qhov muag ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua tau zoo thiab kev ua haujlwm ntawm ntau yam khoom siv kho qhov muag. Ntawm ntau qhov kev tshawb pom tshiab hauv daim teb no, cov txheej txheem kho qhov muag PVD yog qhov txheej txheem uas ntxim nyiam tshaj plaws. Raws li ib qho ntawm thaj chaw loj hlob sai tshaj plaws hauv kev lag luam kho qhov muag, nws tau txais kev saib xyuas dav dav rau nws cov peev xwm tshwj xeeb. Hauv tsab ntawv blog no, peb yuav nkag mus rau hauv qhov nyuaj ntawm cov thev naus laus zis hloov pauv no thiab kawm paub tias nws hloov pauv lub ntiaj teb ntawm kev kho qhov muag li cas.
Txheej Optical PVD (Physical Vapor Deposition) yog ib txoj kev siv tshuab ua kom nyias nyias uas muaj cov txheej txheem sib npaug thiab sib xws ntawm cov khoom siv rau ntawm cov khoom siv kho qhov muag. Cov txheej txheem tso cov khoom siv no tshwm sim hauv lub tshuab nqus tsev uas ntau yam khoom siv xws li hlau thiab oxides raug evaporated thiab condensed rau ntawm qhov chaw ntawm cov khoom siv. Cov txheej txheem ua rau cov khoom siv kho qhov muag zoo dua xws li kev cuam tshuam, kev xa mus thiab kev ruaj khov, ua rau nws yog ib qho kev daws teeb meem nrov rau ntau yam kev siv.
Lub peev xwm los tswj cov tuab ntawm cov txheej, cov khoom sib xyaw thiab cov qauv yog qhov sib txawv ntawm cov txheej PVD optical los ntawm lwm cov txheej txheem txheej ib txwm muaj. Los ntawm kev kho cov kev ntsuas no kom raug, cov chaw tsim khoom tuaj yeem ua tiav cov khoom siv optical xav tau, xws li tiv thaiv kev cuam tshuam lossis kev cuam tshuam siab, nyob ntawm seb daim ntawv thov xav tau. Qib kev hloov kho no ua kom ntseeg tau tias cov txheej optics ua haujlwm zoo tshaj plaws thiab ua tau raws li cov kev xav tau tshwj xeeb ntawm ntau yam lag luam.
Cov ntawv thov rau cov txheej txheem PVD kho qhov muag muaj ntau yam thiab sib txawv. Ib qho tseem ceeb uas cov thev naus laus zis no muaj kev cuam tshuam loj yog hauv kev sib txuas lus. Fiber optics, lub hauv paus ntawm cov kab ke sib txuas lus niaj hnub no, feem ntau raug kev poob siab ntawm cov teeb liab vim yog kev cuam tshuam ntawm lub teeb tsis xav tau. Txhawm rau kom txo qhov teeb meem no, cov txheej txheem PVD kho qhov muag tau siv rau ntawm qhov kawg ntawm fiber, uas txo qhov kev poob ntawm kev cuam tshuam thiab txhim kho kev ua haujlwm ntawm kev xa cov teeb liab.
Lwm daim ntawv thov zoo siab rau cov txheej txheem PVD kho qhov muag yog kev tsim cov iav tsom iav uas raug. Los ntawm kev txheej cov iav no nrog cov ntaub ntawv xaiv zoo rau cov khoom cuam tshuam lossis tiv thaiv kev cuam tshuam, kev ua haujlwm pom kev zoo tag nrho tau txhim kho zoo heev. Qhov no tau hloov pauv kev lag luam xws li kev thaij duab, microscopy thiab laser thev naus laus zis, qhov twg kev tswj hwm lub teeb meej yog qhov tseem ceeb.
Ntxiv rau, cov txheej txheem PVD kho qhov muag tau nkag mus rau hauv kev lag luam tsheb. Cov teeb taub hau thiab daim iav tau coated nrog cov thev naus laus zis, uas txhim kho qhov pom kev thiab txo qhov ci ntsa iab rau kev tsav tsheb muaj kev nyab xeeb dua. Kev lag luam aerospace kuj tau txais txiaj ntsig los ntawm cov thev naus laus zis no vim nws txhim kho kev ua haujlwm ntawm cov sensors kho qhov muag thiab cov duab siv hauv kev tsav dav hlau thiab kev soj ntsuam.
Lub zeem muag yav tom ntej ntawm kev siv tshuab PVD los ua kom pom kev zoo nkauj yog qhov dav heev. Kev tshawb fawb thiab kev txhim kho tas mus li tab tom ua rau muaj kev siv tshuab tshiab hauv ntau yam lag luam. Raws li qhov xav tau ntawm cov khoom siv kho qhov muag ua tau zoo txuas ntxiv mus, cov chaw tsim khoom tab tom tshawb nrhiav cov ntaub ntawv tshiab thiab cov thev naus laus zis los thawb cov ciam teb ntawm cov thev naus laus zis no.
