PVD txheej - cov txheej txheem kev tsim cov hmoov txheej; Hmoov txheej, siab lubrication, oxidation kub, txheej tshuab nqus tsev, PVD txheej tuam txhab, kev sib txhuam coefficient tsawg, txhim kho qhov nyuaj ntawm cov npoo; Ua haujlwm zoo tshaj plaws, txais tos rau kev nug ~
PVD yog dab tsi? Kev daws teeb meem rau cov lus nug ntsig txog tshuab nqus plating plua plav kom nqus cov txheej txheem:
Cov yam ntxwv ntawm PVD: PVD thev naus laus zis tshwm sim hauv kev npaj cov yeeb yaj kiab nrog lub siab hardness, tsis tshua muaj kev sib txhuam coefficient, zoo hnav tsis kam thiab tshuaj lom neeg ruaj khov.
Txheej txheem cej luam ntawm PVD: PVD kuj tseem hu ua rational vapor deposition, hais txog kev siv cov txheej txheem ntawm lub cev kom ua tiav cov khoom xa mus, hloov chaw ntawm atoms lossis molecules los ntawm qhov xa mus rau txheej txheej txheej txheej txheej txheej.
Daim ntawv thov ntawm PVD: txog tam sim no, lub cev vapor deposition thev naus laus zis tsis tuaj yeem tsuas yog nqus hlau zaj duab xis, txhuas zaj duab xis, tab sis kuj tuaj yeem tso cov khoom sib txuas, tej hub, semiconductor, polymer film, thiab lwm yam
PVD txheej thev naus laus zis yog siv los plating zaj duab xis txheej, nrog lub siab hardness, siab hnav tsis kam (tsis tshua muaj kev sib txhuam coefficient), zoo corrosion tsis kam thiab tshuaj lom neeg ruaj khov, zaj duab xis lub neej ntev dua; tib lub sijhawm, zaj duab xis txheej tau zoo heev txhim kho kom zoo nkauj kev ua haujlwm ntawm qhov chaw ua haujlwm.
PVD txheej txheem tshuab yog ib puag ncig zoo rau txheej txheem kev kho mob uas tuaj yeem tau txais micron qib txheej txheej tsis muaj kuab paug. Nws tuaj yeem npaj ntau cov yeeb yaj kiab hlau (xws li txhuas, titanium, zirconium, chromium, thiab lwm yam), nitride films (TiN [titanium], ZrN [zirconium], CrN, TiAlN), carbide films (TiC, TiCN), thiab oxide cov yeeb yaj kiab (xws li TiO, thiab lwm yam).

Txawm hais tias kev siv PVD txheej txheem tshuab tuaj yeem plated tawm ntawm cov txheej txheej zaj duab xis zoo, tab sis tus nqi ntawm PVD txheej txheem qhov tseeb tsis yog qhov siab, nws yog qhov kev siv nyiaj ntau dhau los kho cov txheej txheem, yog li xyoo tsis ntev los no, PVD txheej txheej tshuab tau tsim ceev heev.PVD txheej tau dhau los ua cov kev taw qhia kev txhim kho ntawm kev kho saum npoo hauv kev lag luam kho vajtse.
