Chiyambi cha mfundo ya PVD

mawu oyamba:

M'dziko laukadaulo wapamwamba kwambiri, Physical Vapor Deposition (PVD) imatuluka ngati njira yopititsira patsogolo magwiridwe antchito ndi kulimba kwa zida zosiyanasiyana. Kodi munayamba mwadzifunsapo kuti njira yamakonoyi imagwirira ntchito bwanji? Masiku ano, tikufufuza zamakanikidwe ovuta a PVD, tikumamvetsetsa bwino momwe imagwirira ntchito komanso mapindu ake. Werengani kuti mudziwe momwe PVD imagwirira ntchito komanso kufunikira kwake m'mafakitale osiyanasiyana.

Kumvetsetsa PVD:

Physical Vapor Deposition, yomwe imadziwika kuti PVD, ndi njira yoyika mafilimu yopyapyala yomwe imaphatikizapo kusamutsa maatomu kapena mamolekyu kuchokera kugwero lolimba kupita kumtunda pogwiritsa ntchito njira zakuthupi. Njirayi imagwiritsidwa ntchito kwambiri kupititsa patsogolo zida zamitundu yosiyanasiyana, monga zitsulo, mapulasitiki, ceramics, ndi zina zambiri. Njira ya PVD imachitidwa pansi pa mikhalidwe yopanda kanthu, kuwonetsetsa kuwongolera kolondola pamapangidwe amafilimu opyapyala.

Njira ya PVD:

Njira ya PVD ingagawidwe m'magulu anayi: kukonzekera, kutuluka kwa nthunzi, kuika, ndi kukula. Tiyeni tione gawo lililonse mwatsatanetsatane.

1. Kukonzekera:

Asanayambe kuyika, zinthu zomwe ziyenera kuphimbidwa zimayeretsedwa bwino. Njirayi imatsimikizira kuti pamwamba pamakhala opanda zonyansa, monga mafuta, zigawo za oxide, kapena particles zakunja, zomwe zingalepheretse kumamatira. Malo abwino kwambiri ndi ofunikira kuti mukwaniritse zokutira zapamwamba komanso moyo wautali wazinthu.

2. Kutentha:

Pa nthawiyi, zinthu zomwe zimagwiritsidwa ntchito popanga zokutira, zomwe zimatchedwa kuti source material, zimasanduka nthunzi. Zomwe zimayambira zimayikidwa m'chipinda chopanda vacuum, momwe zimayendetsedwa ndi mphamvu yamafuta kapena ma elekitironi. Zotsatira zake, ma atomu kapena mamolekyu ochokera kumagwero amasinthidwa, kupanga flux.

3. Kuyika:

Pamene gwero la gwero lakhala nthunzi, nthunziwo umadutsa mu chipinda chounikira ndi kukafika pagawo la gawo lapansi. Gawo lapansi, lomwe nthawi zambiri limakutidwa, limayikidwa pafupi ndi gwero la nthunzi. Panthawi imeneyi, tinthu ta nthunzi timalowa pamwamba pa gawo lapansi, zomwe zimapangitsa kuti filimu yopyapyala ikhalepo.

4. Kukula:

Ndi atomu iliyonse kapena molekyulu ikamatera pa gawo lapansi, filimu yowondayo imakula pang'onopang'ono. Mphamvu za kukula kumeneku zimatha kusinthidwa ndikusintha magawo monga nthawi yoyika, kutentha, ndi kupanikizika. Izi zimathandizira kuwongolera makulidwe, kufanana, ndi kapangidwe ka filimuyo, zomwe zimapangitsa kuti filimuyo ikhale yogwirizana kuti ikwaniritse zofunikira zenizeni.
