Tau ntau xyoo los no, muaj kev nce qib tseem ceeb hauv kev siv tshuab txheej, ib qho ntawm cov no yog kev siv tshuab electron beam PVD (Physical Vapor Deposition). Cov thev naus laus zis tshiab no muab kev ua kom zoo ntawm electron beam evaporation nrog rau qhov tseeb ntawm PVD los tsim cov txheej txheem txheej zoo thiab zoo.
Yog li, e-beam PVD yog dab tsi tiag? Hauv kev luv luv, nws cuam tshuam txog kev tso cov zaj duab xis nyias nyias rau ntawm ntau qhov chaw siv cov kab hluav taws xob muaj zog siab. Cov kab no ua rau cov khoom siv vaporizes, uas tom qab ntawd condenses rau ntawm lub substrate xav tau los ua ib txheej nyias, sib xws. Qhov tshwm sim yog qhov ruaj khov thiab zoo nkauj tiav uas ua rau e-beam PVD yog thawj qhov kev xaiv rau ntau yam kev siv.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm e-beam PVD yog lub peev xwm los yooj yim txheej cov duab thiab cov qauv nyuaj. Qhov no txhais tau tias cov lag luam xws li tsheb, aerospace thiab electronics tuaj yeem tau txais txiaj ntsig zoo los ntawm cov thev naus laus zis no. Txawm hais tias nws yog ib qho txheej tiv thaiv rau cov khoom siv dav hlau lossis ib qho tiav kho kom zoo nkauj rau cov khoom siv hluav taws xob, electron beam PVD muab kev ua tau zoo heev.
Lwm yam tseem ceeb ntawm electron beam PVD yog nws txoj kev phooj ywg ib puag ncig. Tsis zoo li cov txheej txheem txheej txheem ib txwm muaj, uas feem ntau muaj cov tshuaj lom neeg txaus ntshai, electron beam PVD yog ib qho txheej txheem huv si thiab ruaj khov. Nws tsim cov khib nyiab tsawg kawg nkaus thiab muaj kev cuam tshuam me ntsis rau ib puag ncig, ua rau nws zoo tagnrho rau cov tuam txhab uas tsom mus rau kev txo lawv cov pa roj carbon dioxide.
Tsis tas li ntawd xwb, cov txheej PVD uas siv hluav taws xob muaj qhov nplaum zoo heev thiab tawv, ua kom muaj kev tiv thaiv ntev tiv thaiv kev hnav, xeb thiab lwm yam kev puas tsuaj. Lub zog siab ntawm cov txheej hluav taws xob tso cai rau kev tswj hwm qhov tuab thiab cov khoom sib xyaw ntawm cov txheej, ua rau cov kws ua haujlwm kho cov txheej kom ua tau raws li cov kev xav tau tshwj xeeb.
Tsis ntev los no muaj xov xwm tshwm sim hais tias ib lub koom haum tshawb fawb loj tau tshaj tawm txog kev tshawb pom tshiab hauv kev siv tshuab electron beam PVD. Lawv pab neeg tau ua tiav hauv kev nce tus nqi tso tawm yam tsis muaj kev cuam tshuam rau kev ua kom zoo ntawm cov txheej. Qhov kev nce qib no qhib cov cib fim tshiab rau cov lag luam uas xav tau kev tsim khoom sai dua yam tsis muaj kev cuam tshuam rau qhov zoo.
Xaus lus, e-beam PVD sawv cev rau qhov kev hloov pauv tshiab hauv kev siv tshuab txheej. Nws lub peev xwm los xa cov khoom zoo tshaj plaws, kev hloov pauv tau yooj yim thiab cov yam ntxwv ib puag ncig ua rau nws yog qhov kev daws teeb meem nrov thoob plaws hauv kev lag luam. Thaum muaj ntau R&D txuas ntxiv txhim kho cov thev naus laus zis, peb xav tias e-beam PVD yuav dhau los ua ntau dua hauv kev tsim khoom, tsav tsheb tsim kho tshiab thiab tsim cov khoom zoo.
