Maitiro ekuisa vapor mumuviri (PVD) akavakirwa pakupisa kwemvura,Hunhu hwefirimu hahungoonekwi chete ne vacuum level, substrate material, kana process parameters. Magadzirirwo echimiro che evaporation source anoita basa guru mukuona kugadzikana kwe deposition, kufanana kwefirimu, microstructure, uye repeatment process kwenguva refu.
Sezvo mashandisirwo ekuputira achiramba achiwedzera kusvika pakugadzira magirazi emotokari, magirazi ekushongedza, mafirimu ekudzivirira anoshanda, uye nzvimbo dzemagirazi, zvinodiwa kuti firimu rirambe rakafanana uye rive rakavimbika zvave kuramba zvichiwedzera kuoma. Pasi pemamiriro ezvinhu aya, dhizaini yenzvimbo yekubuda kwemvura haisisiri chinhu chechipiri chaunofanira kufunga nezvacho—ichinhu chakakosha pakugadzira magadzirirwo emagetsi.
1. Kunobva Kubuda Kwemvura Mukati meKuumbwa Kwemafirimu
Muhurongwa hwekubuda kwemvura mumhepo inopisa, sosi yekubuda kwemvura inoshanda senzvimbo huru yekubuda kwemvura mumhepo, ichisarudza zvakananga:
Kugadzikana kwehuwandu hwekubuda kwemvura
Kupararira kwemarudzi akapwanyika nemhepo
Kugoverwa kwesimba rezvimedu zveutsi
Kuenderana kwenguva pfupi kwekubuda kwezvinhu
Chero kusagadzikana kana kudziviswa kwechimiro padanho rekutanga kuchapararira kuburikidza nemaitiro ese ekuisa zvinhu, zvichizoonekwa sekuchinja kweukobvu hwefirimu, kusabatana zvakanaka, kana zvikanganiso zve microstructure.
2. Kugadzika Kwechivakwa Uye Kugadzikana Kwekubuda Kwemvura
2.1 Kufanana kwekupisa uye kutamiswa kwekupisa
Nzvimbo yekubuda kwemvura yakagadzirwa zvakanaka inofanira kuve nechokwadi chekuti kupisa kuri kupararira zvakaenzana pazvinhu zvekubuda kwemvura. Kupisa kusina kuenzana kunogona kukonzera kupisa kwakanyanya munzvimbo, kusvipira zvinhu, kana kupera simba nguva isati yakwana, zvichikonzera:
Kuchinja-chinja kwemitengo yekuisa zvinhu
Kusvibiswa kwezvikamu
Kuwedzera kwekuoma pamusoro
Geometry yakagadzirwa zvakanaka, pamwe chete nezvinhu zvakakodzera zvekupisira uye marongerwo echinhu chinodziya, zvinobatsira kuchengetedza kupwa kwemvura kwakasimba panguva yakareba yekuputira.
2.2 Kudya Nekushandisa Zvakanaka Zvinhu
Zvinhu zvinofungwa nezvazvo muchimiro chazvo zvakaita semagadzirirwo emidziyo, kudzika kwemidziyo, uye dhizaini yekuburitsa utsi zvinokanganisa zvakananga kushandiswa zvakanaka kwezvinhu. Manyuko asina kugadzirwa zvakanaka anogona kukanganiswa ne:
Kupwanya zvinhu zvisina kukwana
Kugadziriswa kwemvura uye kuiswazve kwemvura mukati mechinhu chacho
Kuderera kwegoho rekufukidza uye mitengo yepamusoro yekushanda
Sosi yemvura yakagadziriswa inogonesa kushandiswa kwezvinhu zvakarongwa uye maitiro ekufungidzira ekuisa zvinhu, izvo zvakakosha pakugadzirwa kwemaindasitiri.
3. Kugoverwa kweVapor Flux uye Kufanana kweFirimu
3.1 Kutungamira uye Kupararira kweAngular
Hukama hwejometri pakati penzvimbo inobuda mvura ne substrate hunosarudza kupararira kwemvura inobuda. Kugadzirwa kwenzvimbo isina kunaka kunogona kukonzera:
Ukobvu hwefirimu husina kufanana munzvimbo huru
Kutetepa kwemucheto kana kukora kwepakati
Chitarisiko chemaziso kana chekushongedza chisingaenderane
Zvivakwa zvemhando yepamusoro zvemanyuko emvura zvakagadzirwa kuti zvipe hutsi hwakasimba uye hunodzorwa, zvichiita kuti huve nechokwadi chekuti hunhu hwakaenzana kunyangwe pazvinhu zvakaoma kana kuti zvine mativi matatu.
3.2 Kudyidzana neSubstrate Motion
Mumasystem emazuva ano ekuputira, dhizaini yematsime ekubuda kwemvura inofanira kuenderana nekutenderera kwesubstrate, kufamba kwepuraneti, kana nzira dzekufambisa dzakatwasuka. Chinangwa ndechekuwana ukobvu hwefirimu hwakafanana uye kuumbwa kwaro musubstrate dzese, zvisinei nenzvimbo yadzo mukamuri.
4. Kukanganisa paMagadzirirwo eFirimu uye Kunamatira
Kunobva kupwanyika kunokanganisa mafambiro efirimu nenzira isina kunanga nekudzora simba remuchina uye mwero wekusvika kwezvikamu zvemuchina. Mamiriro ekupwanyika akasimba anobatsira ku:
Maumbirwo efirimu rakakora
Kuderera kwezvikanganiso zvekukura kwekoramu
Kubatana kwemukati mefacial kwakagadziridzwa
Mukushandiswa kwakadai sekuputira marambi emotokari kana mafirimu ekudzivirira, uko kunamira uye kugara kwenguva refu kwakakosha, sosi yemhepo yakagadzirwa zvakanaka yakakosha kuti ibudirire.
5. Kudzokororwa Kwemaitiro uye Kuvimbika Kwemaindasitiri
Kubva pamaonero emaindasitiri, kunaka kwepurasitiki kunofanirwa kudzokororwa, kuyerwa, uye kudzorwa. Zvivako zvinobva mukubuda kwemvura zvinosangana nekushanduka-shanduka kwemamiriro ekunze, kupisa kusingawanzoitiki, kana kuunganidzwa kwezvinhu zvinounza kutenderera kwemaitiro nekufamba kwenguva.
Magadzirirwo emhando yepamusoro emvura inobuda mumvura anotarisa pane zvinotevera:
Kugadzikana kwenguva refu kwechimiro
Zviri nyore kugadzirisa uye kutsiva zvinhu
Kushanda kwakasimba mumatanho akawanda ekugadzira
Zvinhu izvi zvinokanganisa zvakananga nguva yekushanda kwemidziyo, mwero wegoho, uye mutengo wezvose zvemuridzi wayo.
6. Mhedziso
Muma "vacuum coating systems" anogadzirwa nekupisa, "evaporation source" yacho inopfuura chinhu chinobata kana kuti chinhu chinodziisa. Chinhu chakakosha chinotsanangura maitiro ayo chinokanganisa zvakananga kunaka kwefirimu, kugadzikana kwekugadzirwa, uye kuvimbika kwe "coating".
Sezvo matekinoroji ekuputira achichinja kuita kuti pave nekushanda kwakasimba uye kushivirira kwakasimba, magadzirirwo ekungwarira echimiro chemushonga wekupwanya kwave chinhu chakakosha. Kune vagadziri vari kutsvaga mafirimu matete anogara aripo, emhando yepamusoro mukushandiswa kwakaoma, kuisa mari mukugadzira musanganiswa wemushonga wekupwanya hakusi sarudzo - chinhu chakakosha.
