PVD txheej yog ib qho ntawm cov thev naus laus zis tseem ceeb rau kev npaj cov ntaub ntawv nyias nyias
Cov zaj duab xis txheej endows cov khoom nto nrog hlau zoo nkauj thiab nplua nuj xim, txhim kho hnav tsis kam thiab corrosion kuj, thiab ncua kev pab cuam lub neej.
Sputtering thiab lub tshuab nqus tsev vacuum yog ob txoj hauv kev tseem ceeb tshaj plaws PVD txheej.
1. Kev txhais
Lub cev vapor deposition yog ib hom ntawm lub cev vapor tshuaj tiv thaiv txoj kev loj hlob.Cov txheej txheem deposition yog nqa tawm nyob rau hauv lub tshuab nqus tsev los yog tsis tshua muaj siab gas paug tej yam kev mob, uas yog, nyob rau hauv uas tsis muaj-kub plasma.
Cov khoom siv ntawm txheej txheej yog cov khoom siv tawv.Tom qab "evaporation lossis sputtering", cov khoom siv tshiab txheej txheej txawv kiag li ntawm cov khoom siv hauv paus kev ua tau zoo yog tsim rau ntawm qhov chaw.
2, Cov txheej txheem yooj yim ntawm PVD txheej
1. Emission ntawm hais los ntawm raw khoom (los ntawm evaporation, sublimation, sputtering thiab decomposition);
2. Cov khoom raug thauj mus rau hauv lub substrate (cov khoom sib tsoo nrog ib leeg, ua rau ionization, recombination, cov tshuaj tiv thaiv, kev sib pauv zog thiab kev hloov pauv ntawm kev hloov pauv);
3. Cov particles condense, nucleate, loj hlob thiab tsim zaj duab xis ntawm substrate.
