intshayelelo:
Kwihlabathi lobunjineli bomphezulu obuphambili, iPhysical Vapor Deposition (PVD) ivela njengendlela yokuya ekuphuculeni ukusebenza kunye nokuqina kwezinto ezahlukeneyo. Ngaba wakha wazibuza ukuba le ndlela yokusika iyasebenza njani? Namhlanje, sigocagoca kubuchwephesha obuntsonkothileyo bePVD, sibonelela ngengqiqo ebanzi yokusebenza kwayo kunye neenzuzo ezibonelela ngazo. Funda ukuze ufumane ukusebenza kwangaphakathi kwePVD kunye nokubaluleka kwayo kumashishini ahlukeneyo.
Ukuqonda iPVD:
I-Physical Vapor Deposition, eyaziwa ngokuba yi-PVD, yindlela yokubeka ifilimu ecekethekileyo ebandakanya ukuhambisa iiathomu okanye iiathom ukusuka kumthombo oqinileyo ukuya kumphezulu ngendlela ebonakalayo. Ubuchwephesha busetyenziswa ngokubanzi ukukhulisa iipropathi zomphezulu zezinto ezahlukeneyo, njengesinyithi, iiplastiki, iiseramics, nokunye. Inkqubo ye-PVD yenziwa phantsi kweemeko ze-vacuum, iqinisekisa ulawulo oluchanekileyo malunga nokuqulunqwa kweefilimu ezincinci.
Inkqubo yePVD:
Inkqubo yePVD inokwahlulwa ibe ngamanyathelo amane aphambili: ukulungiselela, ukuba ngumphunga, ukubekwa kunye nokukhula. Makhe sihlolisise isigaba ngasinye ngokweenkcukacha.
1. Ukulungiselela:
Ngaphambi kokuba uqalise inkqubo yokubeka, izinto eziza kugqunywa zicocwa ngononophelo. Eli nyathelo liqinisekisa ukuba umphezulu ukhululekile kwizinto ezingcolileyo, ezifana negrisi, i-oxide layers, okanye iincinci zangaphandle, ezinokuthi zithintele ukunamathela. Umphezulu ococekileyo ubalulekile ekufezekiseni umgangatho ophezulu wokugquma kunye nobomi obude bemathiriyeli.
2. Ukuguquka kwamanzi:
Kweli nqanaba, izinto ezisetyenziselwa ukwenza i-coating, ebizwa ngokuba yi-source material, i-evaporated. Imithombo yomthombo ibekwe kwigumbi lokucoca, apho iphantsi kolawulo lwe-thermal okanye i-electron beam beam. Ngenxa yoko, ii-athomu okanye iiathomu ezivela kwimithombo yomthombo zifakwe ngumphunga, zenza i-flux.
3. Ukubekwa:
Nje ukuba umthombo wemithombo uguqulwe ube ngumphunga, umphunga uhamba ngegumyum kwaye ufikelele kumphezulu wesubstrate. I-substrate, edla ngokuba yimathiriyeli eza kugqunywa, ibekwe kwindawo ekufutshane nomthombo womphunga. Ngeli xesha, amasuntswana omphunga achaphazela umphezulu we-substrate, okukhokelela ekubekweni kwefilimu ebhityileyo.
4. Ukukhula:
Nge-athomu nganye okanye i-molecule ehlala kwi-substrate, ifilimu encinci ikhula ngokuthe ngcembe. I-dynamics yale nkqubo yokukhula inokuguqulwa ngokulungelelanisa iiparamitha ezifana nexesha lokubeka, ubushushu kunye noxinzelelo. Ezi parameters zinika amandla ukulawula ubukhulu befilimu, ukufana, kunye nokwakheka kwayo, ekugqibeleni ikhokelele kwiipropathi ezilungiselelwe ukuhlangabezana neemfuno ezithile.
