1. Thezokutira za vacuum evaporationndondomeko zikuphatikizapo evaporation wa zipangizo filimu, zoyendera maatomu nthunzi mu zingalowe mkulu, ndi ndondomeko nucleation ndi kukula kwa nthunzi maatomu padziko workpiece.
2. Kuyika kwa vacuum degree ya zokutira za vacuum ndikokwera, nthawi zambiri 10-510-3Pa. Njira yaulere ya mamolekyu a gasi ndi 1 ~ 10m dongosolo la kukula, lomwe ndi lalikulu kwambiri kuposa mtunda kuchokera ku gwero la evaporation kupita ku workpiece, mtunda uwu umatchedwa evaporation mtunda, kawirikawiri 300 ~ 800mm. Tinthu ting'onoting'ono tomwe timapaka simagundana ndi mamolekyu a gasi ndi ma atomu a nthunzi ndikufika pamalo ogwirira ntchito.
3. The vakuyumu evaporation ❖ kuyanika wosanjikiza si bala plating, ndi nthunzi maatomu amapita molunjika workpiece pansi vakuyumu mkulu. Mbali yokhayo yomwe ikuyang'anizana ndi gwero la evaporation pa workpiece ingapeze filimu yosanjikiza, ndipo mbali ndi kumbuyo kwa workpiece sikungathe kupeza filimu yosanjikiza, ndipo filimuyi imakhala yosauka.
4. Mphamvu ya tinthu tating'onoting'ono evaporation ❖ kuyanika wosanjikiza ndi otsika, ndi mphamvu kufika workpiece ndi kutentha mphamvu kutengedwa ndi evaporation. Popeza workpiece si kukondera pa vakuyumu evaporation ❖ kuyanika, zitsulo maatomu okha kudalira kutentha vaporization pa nthunzi, kutentha evaporation ndi 1000 ~ 2000 °C, ndi mphamvu ananyamula ndi wofanana 0.1 ~ 0.2eV, kotero mphamvu ya filimu tinthu tating'onoting'ono ndi otsika, filimu wosanjikiza ndi zovuta pawiri wosanjikiza ndi mphamvu pawiri wosanjikiza ndi mphamvu ya masanjidwewo ndi wosanjikiza. zokutira.
5. Wosanjikiza wa vacuum evaporation № ali ndi dongosolo labwino. The vakuyumu evaporation plating ndondomeko aumbike pansi mkulu zingalowe, ndi filimu particles mu nthunzi ali kwenikweni atomiki lonse, kupanga pachimake chabwino pamwamba pa workpiece.
