1. Thechophimba cha vacuum evaporationNjirayi imaphatikizapo kusungunuka kwa zinthu zopangidwa ndi filimu, kunyamula maatomu a nthunzi mu vacuum yambiri, ndi njira yopangira nucleation ndi kukula kwa maatomu a nthunzi pamwamba pa workpiece.
2. Mlingo wa vacuum cleaner woyikapo vacuum evaporation ndi wokwera, nthawi zambiri 10-510-3Pa. Njira yaulere ya mamolekyu a gasi ndi kukula kwa 1 ~ 10m, komwe ndi kwakukulu kwambiri kuposa mtunda wochokera ku gwero la evaporation kupita ku workpiece, mtunda uwu umatchedwa mtunda wa evaporation, nthawi zambiri 300 ~ 800mm. Tinthu tomwe timapaka timagundana ndi mamolekyu a gasi ndi maatomu a nthunzi ndipo timafika pa workpiece.
3. Chophimba cha vacuum evaporation sichili chophimba mabala, ndipo maatomu a nthunzi amapita molunjika ku chogwirira ntchito pansi pa vacuum yambiri. Mbali yokhayo yomwe ikuyang'ana gwero la evaporation pa chogwirira ntchito ndi yomwe ingapeze gawo la filimu, ndipo mbali ndi kumbuyo kwa chogwirira ntchito sizingafikire gawo la filimu, ndipo gawo la filimuyo lili ndi mabala osakwanira.
4. Mphamvu ya tinthu tating'onoting'ono ta vacuum evaporation ndi yochepa, ndipo mphamvu yomwe imafika pa workpiece ndi mphamvu ya kutentha yomwe imatengedwa ndi evaporation. Popeza workpiece siili ndi tsankho panthawi ya evaporation, maatomu achitsulo amadalira kutentha kwa evaporation panthawi ya evaporation, kutentha kwa evaporation ndi 1000 ~ 2000 °C, ndipo mphamvu yomwe imatengedwa ndi yofanana ndi 0.1 ~ 0.2eV, kotero mphamvu ya tinthu tating'onoting'ono ta filimu ndi yochepa, mphamvu yolumikizana pakati pa film layer ndi matrix ndi yaying'ono, ndipo n'zovuta kupanga composite coupling.
5. Chophimba cha vacuum evaporation chili ndi kapangidwe kabwino. Njira yopangira vacuum evaporation plating imapangidwa pansi pa vacuum yambiri, ndipo tinthu ta filimu mu nthunzi kwenikweni ndi atomic scale, kupanga pakati pa fine pamwamba pa workpiece.
