Chiyambi cha mfundo ya PVD

chiyambi:

Mu dziko laukadaulo wapamwamba wa pamwamba, Physical Vapor Deposition (PVD) ikuwoneka ngati njira yofunikira kwambiri yowonjezera magwiridwe antchito ndi kulimba kwa zipangizo zosiyanasiyana. Kodi munayamba mwadzifunsapo momwe njira yamakonoyi imagwirira ntchito? Lero, tikufufuza njira zovuta za PVD, zomwe zimatithandiza kumvetsetsa bwino momwe imagwirira ntchito komanso ubwino wake. Pitirizani kuwerenga kuti mudziwe momwe PVD imagwirira ntchito komanso kufunika kwake m'mafakitale osiyanasiyana.

Kumvetsetsa PVD:

Kuyika Nthunzi Yathupi, komwe kumadziwika kuti PVD, ndi njira yoyika filimu yopyapyala yomwe imaphatikizapo kusamutsa maatomu kapena mamolekyu kuchokera ku gwero lolimba kupita pamwamba pogwiritsa ntchito njira zakuthupi. Njirayi imagwiritsidwa ntchito kwambiri kuti iwonjezere mawonekedwe a pamwamba pa zinthu zosiyanasiyana, monga zitsulo, mapulasitiki, ziwiya zadothi, ndi zina zambiri. Njira ya PVD imachitika pansi pa vacuum condition, kuonetsetsa kuti mafilimu opyapyala akuyang'aniridwa bwino.

Njira ya PVD:

Njira ya PVD ingagawidwe m'magulu anayi akuluakulu: kukonzekera, kusungunuka kwa madzi, kuyikamo madzi, ndi kukula. Tiyeni tiwone gawo lililonse mwatsatanetsatane.

1. Kukonzekera:

Musanayambe njira yoyikamo zinthu, zinthu zomwe ziyenera kuphimbidwa zimayeretsedwa mosamala. Gawoli limaonetsetsa kuti pamwamba pake palibe zinthu zodetsa monga mafuta, zigawo za oxide, kapena tinthu tachilendo, zomwe zingalepheretse kumamatira. Malo oyera ndi ofunikira kwambiri kuti zinthuzo zikhale zapamwamba komanso kuti zikhale ndi moyo wautali.

2. Kutuluka kwa nthunzi:

Pa gawo ili, zinthu zomwe zimagwiritsidwa ntchito popanga chophimbacho, chotchedwa gwero la zinthu, zimasanduka nthunzi. Zinthu zomwe zimagwiritsidwa ntchito zimayikidwa mu chipinda chopanda mpweya, komwe zimayikidwa mu mphamvu yolamulira kutentha kapena mphamvu ya ma elekitironi. Zotsatira zake, maatomu kapena mamolekyu ochokera ku gwero la zinthu amasanduka nthunzi, ndikupanga kusintha kwa madzi.

3. Kuyika:

Pamene chinthu choyambira chatha, nthunzi imadutsa m'chipinda chopanda mpweya ndikufikira pamwamba pa chinthucho. Chinthucho, chomwe nthawi zambiri chimakhala chophimbidwa, chimakhala pafupi ndi gwero la nthunzi. Pa nthawiyi, tinthu ta nthunzi timagunda pamwamba pa chinthucho, zomwe zimapangitsa kuti pakhale filimu yopyapyala.

4. Kukula:

Pamene atomu kapena molekyulu iliyonse ikufika pa substrate, filimu yopyapyala imakula pang'onopang'ono. Kusintha kwa njira yokulirayi kumatha kusinthidwa posintha magawo monga nthawi yoyika, kutentha, ndi kupanikizika. Magawo awa amalola kulamulira makulidwe, kufanana, ndi kapangidwe ka filimuyo, zomwe pamapeto pake zimapangitsa kuti ikhale ndi mawonekedwe okonzedwa kuti akwaniritse zofunikira zinazake.
