The girma dokar na injin evaporation shafi fim Layer

A lokacin shafewar evaporation, ƙaddamarwa da haɓakar fim ɗin fim ɗin shine tushen fasahar suturar ion daban-daban

1.Nuclear

Ininjin shafe fasahar,Bayan fim Layer barbashi suna evaporated daga evaporation tushen a cikin nau'i na atoms, suka tashi kai tsaye zuwa workpiece a high injin da samar da fim Layer ta nucleation da girma a saman da workpiece.A lokacin da iska mai iska, makamashin atom ɗin Layer na fim da ke tserewa daga tushen evaporation yana kusan 0.2eV.Lokacin da haɗin kai tsakanin barbashi na fim ɗin fim ɗin ya fi ƙarfin haɗin kai tsakanin atom ɗin Layer ɗin fim da aikin aikin, suna samar da tsibiri tsakiya.Atom Layer na fim guda ɗaya yana tsayawa a saman kayan aikin na tsawon lokacin yin motsi mara daidaituwa, watsawa, ƙaura, ko karo tare da wasu ƙwayoyin zarra don samar da gungu na atomic Yawan ƙwayoyin atom ɗin a cikin gungu na atomic ya kai wani ƙimar mahimmanci, barga. tsakiya yana samuwa, ana kiransa tsakiya mai siffar kamanni.

santsi, kuma ya ƙunshi lahani da matakai da yawa, wanda ke haifar da bambanci a cikin ƙarfin adsorption na sassa daban-daban na workpiece zuwa atom ɗin rediyoaktif.Ƙarfin adsorption na surface na lahani ya fi girma fiye da na al'ada, don haka ya zama cibiyar aiki, wanda ya dace da ƙaddamar da fifiko, wanda ake kira nucleation heterogeneous.Lokacin da haɗin kai ya zama daidai da ƙarfin ɗauri, ko ƙarfin dauri tsakanin ƙwayoyin membrane da aikin aiki ya fi ƙarfin haɗin kai tsakanin ƙwayoyin membrane, tsarin lamellar yana samuwa.A cikin fasaha na ion plating, tsibirin tsibirin yana samuwa a mafi yawan lokuta.

2. Girma

Da zarar an kafa ainihin fim ɗin, yana ci gaba da girma ta hanyar kama abubuwan da suka faru atom. Tsibirin suna girma kuma suna haɗuwa da juna don samar da mafi girma hemispheres, a hankali suna samar da wani yanki na tsibirin hemispherical wanda ya yada saman saman aikin.

Lokacin da makamashin atomic na fim ɗin fim ɗin yana da girma, zai iya yaduwa sosai a saman kuma za a iya samar da fim mai laushi mai laushi lokacin da gungu na atomic masu zuwa sun kasance ƙananan. Tarin da aka ajiye yana da girma, suna wanzuwa a matsayin manyan ɓangarorin ɓangarorin ɓangarorin. saman babban tsibiri yana da tasirin shading mai ƙarfi a kan ɓangaren da ke ɓoye, wato "tasirin inuwa". da haɓakar fifiko, wanda ke haifar da haɓakar ƙima a kan saman don samar da lu'ulu'u na conical ko columnar na isassun girman.Ana samun ɓoyayyen ɓoyayyiyar shiga tsakanin lu'ulu'u na conical kuma ƙimar ƙimar ƙasa tana ƙaruwa. Za'a iya samun nama mai kyau a babban injin, tare da raguwar injin injin, microstructure na membrane ya zama mai kauri da kauri.
