Inkqubo yokugquma i-vacuum ineemfuno eziqinileyo kwimeko yesicelo.Kwinkqubo yevacuum eqhelekileyo, iimfuno zayo eziphambili zococeko lwevacuum zezi: akukho mthombo wongcoliseko oluqokelelweyo kwiindawo okanye kumphezulu wesixhobo esikwi-vacuum, umphezulu wegumbi lokucoca ugudile kwaye awunazo izicubu ezithambileyo, iipores kunye nendawo yekona. , ngoko i-weld kumatshini we-vacuum ayiyi kuchaphazela i-vacuum, kwaye umatshini wokucoca ophezulu awuyi kusebenzisa ioli njenge-lubricant.I-oyile engenawo i-ultra-high vacuum system kufuneka igweme impembelelo ye-oyile ye-oyile ekucoceni, ukusebenza okusebenzayo okanye iimpawu zomphezulu wendawo yokusebenza.Inkqubo yetsimbi ye-vacuum ephezulu kakhulu ihlala isebenzisa i-1Cr18Ni9Ti njengesixhobo solwakhiwo.Ilabhoratri okanye indawo yokusebenzela apho umatshini wokugquma kufuneka ugcinwe ucocekile kwaye ucocekile.
Kwinkqubo yokucoca i-vacuum, unyango lokucoca umphezulu lubaluleke kakhulu.Ngokusisiseko, ngaphambi kokuba zonke ii-substrates zilayishwe kwigumbi lokucoca i-coating, kufuneka zihambe ngenkqubo yokucoca kwangaphambili ukuze kufezekiswe ukucocwa, ukucocwa kunye nokuncipha kwamanzi kwindawo yokusebenza.
Imithombo ephambili yongcoliseko lomphezulu weendawo ezicandiweyo zezi: uthuli, ukubila, igrisi, i-polish paste, i-oyile, i-oyile yokuthambisa kunye nezinye izinto ziya kuthotyelwa ngexesha lokucubungula, ukuhanjiswa, ukupakishwa kunye nezinye iinkqubo;Irhasi idsorbed kwaye ifunxwe kumphezulu wezixhobo zezixhobo;Ifilimu ye-oxide eyenziwe kumphezulu wamacandelo omatshini wokugquma emoyeni omanzi.Ungcoliseko oluvela kule mithombo, uninzi lwazo lunokususwa ngokucoca okanye ukucocwa kweekhemikhali.
Musa ukugcina izinto zokusebenza ezicociweyo kwindawo ye-atmospheri.Ukuze kuncitshiswe ukungcola kothuli kunye nokucoca ukugcinwa kwezinto zokusebenza, ngokuqhelekileyo zisebenzisa iikhabhinethi zokucoca okanye izitya ezivaliweyo zokugcina umsebenzi.I-substrate yeglasi kufuneka igcinwe kwi-container entsha ye-aluminiyam ene-oxidized, enokunciphisa i-adsorption yomphunga we-hydrocarbon.Ngenxa yokuba izikhongozeli ze-aluminiyam ezisanda kufakwa ngeoksijini ziya kuthanda ii-hydrocarbons.Imiphezulu ebuthathaka kumphunga wamanzi okanye engazinzanga kakhulu idla ngokugcinwa kwi-oveni efunxayo yokumisa.
Iimfuno ezisisiseko zenkqubo yokugquma i-vacuum kwindalo ziquka: ukucoceka okuphezulu kwigumbi lokucoca, uthuli olungenalo uthuli kwigumbi lokugquma, njl. amacandelo akwi-substrate kunye ne-vacuum room, kodwa kufuneka enze umsebenzi wokubhaka kunye nokucoca.Ukongezelela, ukwenzela ukukhusela ioli ekungeneni kwigumbi lokucoca, kuyafuneka kwakhona ukuba ubeke ingqalelo kwi-oyile yokubuyisela kunye nemilinganiselo yokuthintela ioli yepompo yokusasaza i-refueling.
