Chophimba cha vacuum evaporation (chotchedwa evaporationcoating) chili pamalo opanda mpweya, evaporator yotentha filimu kuti ipange mpweya, evaporator imayatsa tinthu tating'onoting'ono tomwe timatuluka mwachindunji ku substrate ndi substrate deposition, kupanga ukadaulo wolimba wa filimu. Evaporation ya vacuum ndi ukadaulo wa PVD womwe umapanga ukadaulo wakale kwambiri wa town film, ngakhale kuti pambuyo pake pakukula kwa sputtering ndi ion plating m'mbali zambiri kuposa vacuum evaporation superior, koma ukadaulo wa town film wa vacuum evaporation ukadali ndi zabwino zambiri, monga zida ndi njira ndizosavuta, zonse ziwiri zimakhala ndi filimu yoyera kwambiri, komanso zimatha kukonzedwa ndi kapangidwe ndi mawonekedwe enaake a filimu, ndi zina zotero. Zoyipa zazikulu za njira iyi ndikuti sikophweka kupeza mafilimu okhala ndi kapangidwe ka kristalo, kumamatira kwa filimuyo pa substrate ndi kochepa, ndipo kubwerezabwereza kwa njirayi sikukwanira.
M'zaka zaposachedwapa, chifukwa cha elekitirodi bombardment evaporation, high-frequency induction evaporation, komanso laser evaporation ndi ukadaulo wina mu vacuum evaporation technology ❖ kuyanika mu ntchito yonse ya technology, kotero kuti technology iyi ndi yangwiro kwambiri, ndipo imagwiritsidwa ntchito kwambiri mu makina, magetsi, wailesi, optics, atomiki energy kuti apeze mzinda.
