La daabacay:23-05-24

Inta lagu jiro daahan uumi-baxa, nucleation-ka iyo koritaanka lakabka filimku waa saldhigga tignoolajiyada daahan kala duwan

1.Nuclearka

InTignoolajiyada dahaarka uumiga uumiga,ka dib markii qaybaha lakabka filimka la uumi ka soo isha uumiga qaab atamka ah, waxay si toos ah u duuli workpiece ee vacuum sare oo ay sameeyaan lakabka filimka by nucleation iyo koritaanka dusha workpiece ah.Inta lagu jiro uumiga faakuumka, tamarta lakabka filimaanta atamka ka baxsanaya uumiga waa qiyaastii 0.2eV.Marka isku xidhka u dhexeeya qaybaha lakabka filimku ka weyn yahay xoogga isku xidhka ee u dhexeeya atamka lakabka filimka iyo qaybta shaqada, waxay sameeyaan bu'da jasiiradda.Hal lakab oo atom ah ayaa ku sii jiraya dusha sare ee shaqada inta lagu jiro wakhtiga samaynta dhaqdhaqaaq aan caadi ahayn, faafin, guuritaanka, ama isku dhaca atamka kale si ay u sameeyaan rucubyada atomiga Tirada atamka ee kutlada atamka waxay gaartaa qiimo gaar ah, xasilloon nukleus ayaa samaysmay, oo loo yaqaan bu'dud qaabaysan.

siman, oo ka kooban cillado badan iyo tillaabooyin, taas oo sababta farqiga u xoog adsorption ee qaybaha kala duwan ee workpiece in atamka shucaaca.Tamarta adsorption ee dusha sare ee cilladdu way ka weyn tahay tan caadiga ah, sidaas darteed waxay noqotaa xarun firfircoon, taas oo ku habboon nukleation doorbidista, oo loo yaqaan nucleation heterogeneous.Marka xoogga isku xidhani uu le'eg yahay xoogga isku xidhka, ama xoogga isku xidha ee u dhexeeya atamka xuubka iyo shaqada uu ka weyn yahay xoogga isku xidhan ee u dhexeeya atamka xuubka, qaabka lamellar ayaa la sameeyaa.Tignoolajiyada ion plating, xudunta jasiiradda ayaa la sameeyay kiisaska intooda badan.

2.Kobaca

Marka xudunta u ah filimka la sameeyay, waxay sii wadaysaa inay koraan iyada oo dabinaysa atomamka dhacdada. Jasiiraduhu way koraan oo isku daraan midba midka kale si ay u sameeyaan hemispheres weyn, si tartiib tartiib ah u samee lakabka jasiiradda hemispherical kaas oo ku faafaya dusha sare ee workpiece.

Marka tamarta atamka ee lakabka filimku uu sarreeyo, waxay si ku filan ugu faafi kartaa dusha sare iyo filim joogto ah oo siman ayaa la samayn karaa marka kooxaha atomiga ee soo socda ay yar yihiin. Haddii faafinta atamka ee dusha sare ay daciif tahay iyo cabbirka Dusha sare ee jasiiradda xudunta u ah waxay leedahay saamayn hadh xoog leh oo ku saabsan qaybta concave, taas oo ah "saamaynta hadh". iyo korriinka doorbidka leh, taasoo keentay in kor u kaca heerka miyir-beelka ee dusha sare si uu u sameeyo kareemooyin konical ama tiirar ah oo cabbir ku filan leh.Bannaanka dhex galka ah ayaa ka dhex abuurma kiristaalo conical ah, qiimaha qallafsanaanta dusha sare ayaa kor u kaca. Nudaha fiican waxaa laga heli karaa vacuum sare, iyadoo hoos u dhaca heerka faakuumka, qaabdhismeedka yar ee xuubka ayaa noqda mid dhumuc iyo dhumuc leh.
