1. Isantya somphunga siya kusebenza kwiipropathi ze-evaporated coating
Izinga lokuguquka komphunga linempembelelo enkulu kwifilimu efakiweyo.Ngenxa yokuba ulwakhiwo lokugquma olubunjwe ngesantya esiphantsi sokubekwa lukhululekile kwaye kulula ukuvelisa ukubekwa kwamasuntswana amakhulu, kukhuselekile kakhulu ukukhetha izinga eliphezulu lokunyuka komphunga ukuze kuqinisekiswe ukuthotyelwa kwesakhiwo sokugquma.Xa uxinzelelo lwegesi eseleyo kwigumbi lokucoca lihlala lihlala, izinga le-bombardment ye-substrate lixabiso eliqhubekayo.Ngoko ke, i-gas eseleyo equlethwe kwifilimu egciniweyo emva kokukhetha izinga eliphezulu lokubeka i-deposition iya kuncitshiswa, ngaloo ndlela inciphisa ukusabela kweekhemikhali phakathi kwee-molecule ze-gas eziseleyo kunye neengqungquthela zefilimu e-evaporated.Ngoko ke, ukucoceka kwefilimu egciniweyo kunokuphuculwa.Kufuneka kuqatshelwe ukuba ukuba izinga lokubeka likhawuleza kakhulu, linokunyusa uxinzelelo lwangaphakathi lwefilimu, luya kwandisa iziphene kwifilimu, kwaye luze lukhokelele ekuqhekekeni kwefilimu.Ngokukodwa, kwinkqubo ye-reactive evaporation plating, ukuze wenze i-reactivity yegesi isabele ngokupheleleyo kunye namasuntswana ezinto zefilimu ephuphumayo, ungakhetha ireyithi yokubeka esezantsi.Ngokuqinisekileyo, izixhobo ezahlukeneyo zikhetha amazinga ahlukeneyo okuphuma komphunga.Njengomzekelo osebenzayo- ukubekwa kwefilimu ebonakalisayo, Ukuba ubukhulu befilimu yi-600 × 10-8cm kwaye ixesha lokuphuma komphunga liyi-3s, ukubonakaliswa yi-93%.Nangona kunjalo, ukuba izinga lokuphuma kwamanzi liyancipha phantsi kwemeko yobukhulu obufanayo, kuthatha imizuzu eyi-10 ukugqiba ukubeka ifilimu.Ngeli xesha, ubukhulu befilimu bufana.Nangona kunjalo, ukubonakala kwehle ukuya kuma-68%.
2. Iqondo lobushushu elingaphantsi liya kusebenza kwi-evaporation coating
Ubushushu be-substrate bunempembelelo enkulu kwi-evaporation coating.Iimolekyuli zerhasi ezishiyekileyo ezibhengezwe kumphezulu we-substrate kubushushu obuphezulu be-substrate kulula ukususwa.Ngokukodwa ukupheliswa kweemolekyuli zomphunga wamanzi kubaluleke ngakumbi.Ngaphezu koko, kumaqondo okushisa aphezulu, akulula nje ukukhuthaza ukuguqulwa komzimba kwi-adsorption ye-chemical adsorption, ngaloo ndlela ukwandisa amandla okubopha phakathi kwamaqhekeza.Ngaphezu koko, kunokunciphisa umahluko phakathi kweqondo lokushisa elihlaziyiweyo leemolekyuli zomphunga kunye nobushushu be-substrate, ngaloo ndlela ukunciphisa okanye ukuphelisa uxinzelelo lwangaphakathi kwi-interface esekwe kwifilimu.Ukongezelela, ngenxa yokuba ukushisa kwe-substrate kuhambelana ne-crystalline state yefilimu, ngokuqhelekileyo kulula ukwenza i-amorphous okanye i-microcrystalline coatings phantsi kwemeko yokushisa kwe-substrate ephantsi okanye akukho ukufudumeza.Ngokuchasene noko, xa ubushushu buphezulu, kulula ukwenza i-crystalline coating.Ukwandisa ukushisa kwe-substrate kukwanceda ekuphuculeni iimpawu zomatshini zokugquma.Ngokuqinisekileyo, ubushushu be-substrate akufanele bube phezulu kakhulu ukukhusela ukuvela kwengubo.
3. Uxinzelelo lwerhasi eshiyekileyo kwigumbi le-vacuum luya kusebenza kwiipropati zefilimu
Uxinzelelo lwegesi eseleyo kwigumbi lokucoca linempembelelo enkulu ekusebenzeni kwe-membrane.Iimolekyuli zegesi ezishiyekileyo ezinoxinzelelo oluphezulu kakhulu azilula nje ukungqubuzana neengqungquthela eziphumayo, eziza kunciphisa amandla e-kinetic abantu kwi-substrate kwaye ichaphazele ukunamathela kwefilimu.Ukongeza, uxinzelelo lwegesi oluphezulu kakhulu luya kuchaphazela kakhulu ukucoceka kwefilimu kunye nokunciphisa ukusebenza kwengubo.
4. Isiphumo sobushushu bomphunga kwi-evaporation coating
Isiphumo sobushushu bomphunga kwi-membrane yokusebenza iboniswa ngotshintsho lwesantya sobushushu kunye nobushushu.Xa ubushushu bobushushu buphezulu, ubushushu bomphunga buya kuncipha.Ukuba i-membrane imathiriyeli i-evaporated ngaphezu kobushushu be-evaporation, nokuba utshintsho oluncinci kwiqondo lokushisa lunokubangela utshintsho olubukhali kwisantya sokunyuka kwe-membrane.Ngoko ke, kubaluleke kakhulu ukulawula ubushushu bomphunga ngokuchanekileyo ngexesha lokubekwa kwefilimu ukuphepha i-gradient enkulu yobushushu xa umthombo wokufudumala ushushu.Kwizinto zefilimu ezilula ukuzithoba, kubaluleke kakhulu ukukhetha izinto ngokwazo njenge-heater yokufudumala kunye namanye amanyathelo.
5. Ukucoca imeko ye-substrate kunye negumbi lokugquma liya kusebenza ekusebenzeni kokwambathisa
Umphumo wokucoceka kwe-substrate kunye negumbi lokugubungela ekusebenzeni kwengubo ayinakungahoywa.Ayiyi kuchaphazela kakhulu kuphela ukucoceka kwefilimu egciniweyo, kodwa nokunciphisa ukunamathela kwefilimu.Ngoko ke, ukucocwa kwe-substrate, ukucocwa kokucoca kwegumbi lokugubungela i-vacuum kunye nezixhobo ezihambelanayo (ezifana nesakhelo se-substrate) kunye ne-surface degassing zizo zonke iinkqubo eziyimfuneko kwinkqubo yokugqoka i-vacuum.
