Kodi ukadaulo wokutira wa PVD ndi chiyani?

Kuphimba kwa PVD ndi imodzi mwa njira zazikulu zopangira zinthu zopyapyala za filimu

Filimuyi imapatsa pamwamba pake mawonekedwe achitsulo ndi mtundu wowala, imawonjezera kukana kuwonongeka ndi kukana dzimbiri, komanso imawonjezera nthawi yogwira ntchito.

Kutulutsa madzi ndi kupopera mpweya ndi njira ziwiri zodziwika bwino zophikira PVD.

1, Tanthauzo

Kuyika nthunzi ya thupi ndi mtundu wa njira yokulira ya nthunzi ya thupi. Njira yoyika nthunzi imachitika pansi pa vacuum kapena mpweya wochepa, kutanthauza, mu plasma yotsika kutentha.

Gwero la chophimbacho ndi chinthu cholimba. Pambuyo pa "kutuluka kwa nthunzi kapena kutulutsa madzi", chophimba chatsopano cholimba chosiyana kwambiri ndi momwe zinthu zoyambira zimagwirira ntchito chimapangidwa pamwamba pa gawolo.

2, Njira yoyambira yopangira PVD

1. Kutuluka kwa tinthu tating'onoting'ono kuchokera ku zinthu zopangira (kudzera mu nthunzi, kusungunuka kwa madzi, kutayikira ndi kuwonongeka);

2. Tinthu tating'onoting'ono timasamutsidwira ku substrate (tinthu tating'onoting'ono timagundana, zomwe zimapangitsa kuti ionization, recombination, reaction, energy exchange and movement direction change);

3. Tinthu tating'onoting'ono timaundana, timapanga nucleate, timakula ndikupanga filimu pa substrate.
