intshayelelo:
Kwihlabathi lobunjineli bomphezulu obuphambili, iPhysical Vapor Deposition (PVD) ivela njengendlela esetyenziswa kakhulu ekuphuculeni ukusebenza kunye nokuqina kwezixhobo ezahlukeneyo. Ngaba wakha wazibuza ukuba le ndlela intsha isebenza njani? Namhlanje, sijonga indlela entsonkothileyo yePVD, sinikezela ngokuqonda okubanzi kokusebenza kwayo kunye neenzuzo ezibonelelayo. Qhubeka ufunda ukuze ufumane indlela esebenza ngayo iPVD kunye nokubaluleka kwayo kumashishini ahlukeneyo.
Ukuqonda i-PVD:
Ukususwa koMphunga oPhilayo, okwaziwa ngokuba yiPVD, yindlela yokubeka ifilimu encinci equka ukudlulisa iiathom okanye iimolekyuli ukusuka kumthombo oqinileyo ukuya kumphezulu ngeendlela ezibonakalayo. Le ndlela isetyenziswa kakhulu ukuphucula iipropati zomphezulu wezinto ezahlukeneyo, ezifana neesinyithi, iiplastiki, iiseramikhi, nokunye. Inkqubo yePVD yenziwa phantsi kweemeko zokungasebenzi kakuhle, ukuqinisekisa ulawulo oluchanekileyo malunga nokwakheka kweefilimu ezincinci.
Inkqubo ye-PVD:
Inkqubo ye-PVD ingahlulwahlulwa ibe ngamanyathelo amane aphambili: ukulungiswa, ukufuma, ukubekwa kwayo, kunye nokukhula. Makhe sihlolisise isigaba ngasinye ngokweenkcukacha.
1. Ukulungiselela:
Ngaphambi kokuba kuqaliswe inkqubo yokubeka, izinto eziza kugqunywa zicocwa ngononophelo. Eli nyathelo liqinisekisa ukuba umphezulu awunazo izinto ezingcolisayo, ezinje ngamafutha, iileya ze-oxide, okanye amasuntswana angaphandle, anokuthintela ukunamathela. Umphezulu ococekileyo ubalulekile ekufezekiseni iingubo ezisemgangathweni ophezulu kunye nobomi obude bezinto.
2. Ukufuma komphunga:
Kule nqanaba, izinto ezisetyenziselwa ukwenza i-coating, ebizwa ngokuba yi-source material, ziyatshintshwa zibe ngumphunga. Izinto ezisetyenziswayo zifakwa kwigumbi le-vacuum, apho zilawulwa khona ngamandla obushushu okanye e-electron beam. Ngenxa yoko, ii-athomu okanye iimolekyuli ezivela kwizinto ezisetyenziswayo ziyatshintshwa zibe ngumphunga, zenze i-flux.
3. Ukubekwa kwetyala:
Xa izinto ezisisiseko ziphelisiwe, umphunga uhamba ngegumbi le-vacuum uze ufikelele kumphezulu we-substrate. I-substrate, edla ngokuba yinto eza kugqunywa, ibekwe kufutshane nomthombo womphunga. Kule ndawo, amasuntswana omphunga angena kumphezulu we-substrate, nto leyo ebangela ukuba kubekho ifilimu encinci.
4. Ukukhula:
Njengoko iathom okanye imolekyuli nganye ifika kwi-substrate, ifilimu encinci ikhula kancinci kancinci. Iindlela ezisebenza ngayo le nkqubo yokukhula zinokulawulwa ngokulungelelanisa iiparameter ezifana nexesha lokubeka, ubushushu, kunye noxinzelelo. Ezi parameter zivumela ulawulo phezu kobukhulu befilimu, ukufana, kunye nokwakheka kwayo, ekugqibeleni zikhokelela kwiipropati ezilungiselelwe ukuhlangabezana neemfuno ezithile.
