PVD (Tsarin Turin Jiki, Turin jiki na jiki) fasaha ce ta shafi wanda ke adana fina-finai akan saman ƙasa ta hanyar canza tushen kayan (manufa) zuwa barbashi na gas (atom, kwayoyin ko ions) ta hanyoyin jiki a cikin yanayi mara kyau. Mahimmin ka'idar ita ce yin amfani da yanayin yanayi don rage watsar da kwayoyin gas a kan abubuwan da aka ajiye, ƙyale barbashi suyi tafiya a cikin layi mai zurfi zuwa substrate, don haka samun ci gaban fim mai sarrafawa.

 

Nau'o'in tsari gama gari sun haɗa da:

1. Rufin Tururi: Ana fitar da kayan da aka yi niyya ta hanyar dumama juriya, dumama wutar lantarki, da sauransu, kuma ƙwayoyin iskar gas suna taruwa su yi tauri a kan substrate (kamar shirya fina-finan hana haske don ruwan tabarau na gani);

 

2. Rufin da ke toshewa: Ion masu ƙarfi sosai suna jefa saman abin da ake nufi da shi a cikin iska don haifar da ƙwayoyin da ake nufi su tono su kuma su yi tsatsa (kamar shirya na'urorin lantarki na ƙarfe don guntun semiconductor ta hanyar amfani da magnetron sputtering);

 

3. Rufin ion: Ana mayar da barbashin da aka ajiye zuwa ion kuma ana hanzarta su ta hanyar amfani da filin lantarki don yin ruwan sama a kan substrate, yana ƙara mannewar fim ɗin (kamar shirya murfin TiAlN mai jure lalacewa don kayan aikin yankewa ta hanyar amfani da plating na arc ion).

 

Babban fasali na PVD sune:

- Babban tsabtataccen fim, mai yawa mai kyau, da mannewa mai ƙarfi ga substrate;

- sigogi na tsari (kauri, abun da ke ciki, tsari) ana iya sarrafa shi daidai tare da maimaitawa mai kyau;

- Ya dace da nau'ikan kayan (karfe, yumbu, semiconductor, polymers, da sauransu);

- Kyakkyawan aikin muhalli (babu mai cutarwa mai cutarwa, ƙarancin iskar gas).

 

Dukansu simintin gyare-gyare da ƙirƙira na iya ɗaukar PVD (jikin tururi na zahiri) murfin injin, amma dole ne a cika waɗannan sharuɗɗa:

1. Dacewar abu: Dole ne abin da aka yi amfani da shi ya zama ƙarfe (kamar ƙarfe, ƙarfe na aluminum, ƙarfe na titanium, da sauransu) ko kuma kayan yumbu mai takamaiman ƙarfin lantarki da juriyar zafi (zafin aikin PVD yawanci shine 100-500 ° C, kuma yawancin simintin ƙarfe/forgings na iya jure shi).

 

2. Gyaran saman da aka yi kafin a yi amfani da shi: Dole ne a cire lahani a saman kamar su oxide scale, pores, slacking caves, scars, da naɗewa ta hanyar hanyoyin kamar niƙa, gogewa, yashi mai laushi, da wanke acid (lalacewar simintin ya fi bayyana kuma yana buƙatar magani mai tsauri), kuma dole ne a ƙara ƙarfin saman ta hanyar bam ɗin ion da sauran hanyoyin kunnawa don tabbatar da manne fim ɗin.

 

Lura: Simintin gyare-gyare tare da babban abun ciki na carbon kamar simintin ƙarfe yana buƙatar kulawa ta musamman ga kula da lahani don guje wa sakin gas daga pores da ke haifar da gazawar fim; don simintin simintin gyare-gyare na aluminum, dole ne a cire fim ɗin oxide na saman (kamar wanke alkaline), kuma ana iya buƙatar madaurin canji (kamar nickel) don haɓaka mannewa idan ya cancanta.
