isingeniso:
Emhlabeni wobunjiniyela obusezingeni eliphezulu, i-Physical Vapor Deposition (PVD) ivela njengendlela yokuya phambili yokuthuthukisa ukusebenza nokuqina kwezinto ezihlukahlukene. Wake wazibuza ukuthi le ndlela yokusika isebenza kanjani? Namuhla, sihlola ubukhenikha obuyinkimbinkimbi be-PVD, sinikeza ukuqonda okuphelele kokusebenza kwayo kanye nezinzuzo ezinikezayo. Qhubeka ufunda ukuze uthole ukusebenza kwangaphakathi kwe-PVD nokubaluleka kwayo ezimbonini ezihlukahlukene.
Ukuqonda i-PVD:
I-Physical Vapor Deposition, evame ukwaziwa ngokuthi i-PVD, iwuhlelo lokubeka ifilimu elincanyana elihlanganisa ukudlulisa ama-athomu noma ama-molecule ukusuka emthonjeni oqinile ukuya endaweni ngokusebenzisa izinto ezibonakalayo. Le nqubo isetshenziswa kabanzi ukuthuthukisa izakhiwo ezingaphezulu zezinto ezahlukahlukene, njengezinsimbi, ipulasitiki, i-ceramics, nokunye. Inqubo ye-PVD yenziwa ngaphansi kwezimo ze-vacuum, iqinisekisa ukulawula okunembile ekubunjweni kwamafilimu amancane.
Inqubo ye-PVD:
Inqubo ye-PVD ingahlukaniswa ngezinyathelo ezine eziyinhloko: ukulungiselela, ukuhwamuka, ukubekwa, nokukhula. Ake sihlole isigaba ngasinye ngokuningiliziwe.
1. Ukulungiselela:
Ngaphambi kokuqala inqubo yokufaka, impahla ezogcotshwa ihlanzwa ngokucophelela. Lesi sinyathelo siqinisekisa ukuthi indawo engaphezulu ayinakho ukungcola, okufana namafutha, izingqimba ze-oxide, noma izinhlayiya zangaphandle, ezingase zithiye ukunamathela. Indawo ehlanzekile ibalulekile ekuzuzeni ukumbozwa kwekhwalithi ephezulu nempilo ende yezinto ezibonakalayo.
2. Ukuhwamuka:
Kulesi sigaba, izinto ezisetshenziselwa ukwenza i-coating, ebizwa ngokuthi i-source material, iyahwamuka. Izinto eziwumthombo zifakwa egumbini le-vacuum, lapho zingaphansi kwamandla alawulwayo ashisayo noma e-electron beam. Ngenxa yalokho, ama-athomu noma ama-athomu avela kumthombo wempahla ayahwamuka, enze i-flux.
3. Ukubekwa:
Uma impahla yomthombo isihwamukile, umhwamuko uhamba egunjini levacuum futhi ufinyelele endaweni engaphansi. I-substrate, ngokuvamile into ezogcotshwa, ibekwe eduze nomthombo womhwamuko. Kuleli qophelo, izinhlayiya zomhwamuko zigxambukela phezu kwe-substrate, okuholela ekubekweni kwefilimu elincanyana.
4. Ukukhula:
Ngokufika kwe-athomu ngayinye noma i-molecule ku-substrate, ifilimu elincanyana liyakhula kancane kancane. Amandla ale nqubo yokukhula angasetshenziswa ngokulungisa amapharamitha afana nesikhathi sokubeka, izinga lokushisa, nokucindezela. Lawa mapharamitha anika amandla ukulawula ukujiya kwefilimu, ukufana, kanye nokwakheka kwayo, okuholela ezimpahleni eziklanyelwe ukuhlangabezana nezidingo ezithile.
