Kusiyana Pakati pa Kupaka kwa Evaporation ndi Sputtering Coating

Monga tonse tikudziwira, njira zomwe zimagwiritsidwa ntchito popaka vacuum ndizotulutsa mpweya ndi ion sputtering.Kodi pali kusiyana kotani pakati pa zokutira transpiration ndi sputtering zokutira Ambirianthu muli ndi mafunso otere.Tiyeni tigawane nanu kusiyana pakati pa zokutira za transpiration ndi zokutira zopopera

Vacuum transpiration filimu ndi kutentha deta kuti transpiration kwa kutentha kokhazikika mwa kukana Kutentha kapena elekitironi mtengo ndi laser zipolopolo mu chilengedwe ndi vacuum digiri osachepera 10-2Pa, kuti matenthedwe kugwedera mphamvu mamolekyu kapena. ma atomu mu data amaposa mphamvu zomangira zapamtunda, kotero kuti mamolekyu ambiri kapena ma atomu amatuluka kapena kuwonjezeka, ndikuyika mwachindunji gawo lapansi kuti apange filimu.Kupaka kwa ion sputtering kumagwiritsa ntchito kayendedwe kapamwamba ka ma ion abwino opangidwa ndi kutulutsa mpweya pansi pa mphamvu ya magetsi kuti aphulitse chandamale ngati cathode, kotero kuti maatomu kapena mamolekyu omwe ali mu chandamale amatha kuthawa ndikuyika pamwamba pa chogwiriracho kuti apange. filimu yofunika.

Njira yomwe imagwiritsidwa ntchito kwambiri pakupaka vacuum transpiration ndi njira yotenthetsera yopinga.Ubwino wake ndi dongosolo losavuta la kutentha gwero, mtengo wotsika komanso ntchito yabwino.kuipa kwake ndi kuti si oyenera zitsulo refractory ndi kutentha kugonjetsedwa TV.Kutentha kwa ma elekitironi ndi kutentha kwa laser kumatha kuthana ndi kuipa kwa kukaniza kutentha.Potenthetsera mtengo wa ma elekitironi, mtengo wa elekitironi wolunjika umagwiritsidwa ntchito kutenthetsera deta yomwe ili ndi zipolopolo, ndipo mphamvu ya kinetic ya mtengo wa electron imakhala mphamvu ya kutentha kuti data ipite.Kutentha kwa laser kumagwiritsa ntchito laser yamphamvu kwambiri ngati gwero la kutentha, koma chifukwa cha kukwera mtengo kwa laser yamphamvu kwambiri, imatha kugwiritsidwa ntchito m'ma laboratories ochepa chabe.

Luso la sputtering ndi losiyana ndi luso la vacuum transpiration.Sputtering imatanthawuza chodabwitsa chomwe tinthu tating'onoting'ono timawombera pamwamba (chandamale) cha thupi, kotero kuti maatomu olimba kapena mamolekyu amatulutsidwa kuchokera pamwamba.Zambiri mwa tinthu tating'onoting'ono timene timapangidwa ndi atomiki, zomwe nthawi zambiri zimatchedwa maatomu ophulika.Tinthu tating'onoting'ono tomwe timagwiritsa ntchito popangira zipolopolo zitha kukhala ma elekitironi, ma ion kapena tinthu tating'ono.Chifukwa ma ion ndi osavuta kupeza mphamvu yamagetsi yofunikira pansi pamagetsi, ma ion amasankhidwa ngati tinthu tating'onoting'ono.

Dongosolo la sputtering limatengera kutulutsa kowala, ndiko kuti, ma ion a sputtering amachokera kutulutsa mpweya.Maluso osiyanasiyana a sputtering ali ndi njira zosiyanasiyana zotulutsa kuwala.DC diode sputtering imagwiritsa ntchito kutulutsa kowala kwa DC;Triode sputtering ndi kutulutsa kowala komwe kumathandizidwa ndi cathode yotentha;RF sputtering imagwiritsa ntchito kutulutsa kowala kwa RF;Magnetron sputtering ndi kutulutsa kowala komwe kumayendetsedwa ndi maginito a annular.

Poyerekeza ndi zokutira za vacuum transpiration, kupaka utoto kumakhala ndi zabwino zambiri.Ngati chinthu chilichonse chikhoza kutayidwa, makamaka zinthu ndi mankhwala okhala ndi malo osungunuka kwambiri komanso kutsika kwa nthunzi;Kulumikizana pakati pa filimu yotayidwa ndi gawo lapansi ndikwabwino;Kuchuluka kwa mafilimu;Makulidwe a kanema amatha kuyendetsedwa ndipo kubwereza ndikwabwino.Choyipa chake ndi chakuti zidazo ndizovuta ndipo zimafuna zida zamphamvu kwambiri.

Kuphatikiza apo, kuphatikiza kwa transpiration njira ndi sputtering njira ndi ion plating.Ubwino wa njirayi ndi kumamatira mwamphamvu pakati pa filimuyo ndi gawo lapansi, kutsika kwakukulu komanso kusachulukira kwakukulu kwa filimuyo.
