Inkqubo yokugquma i-vacuum ineemfuno eziqinileyo kwimeko yesicelo. Kwinkqubo yokucoca yesiqhelo, iimfuno zayo eziphambili zococeko lwevacuum zezi: akukho mthombo wongcoliseko oluqokelelweyo kwiindawo okanye kumphezulu wesixhobo kwi-vacuum, umphezulu wegumbi lokucoca ugudile kwaye awunazo izihlunu ezithambileyo, iipores kunye nendawo yekona, ngoko ke i-weld kumatshini wokucoca ayiyi kuchaphazela i-vacuum, kwaye umatshini wokucoca i-oyile awuyi kusebenzisa umatshini wokuthambisa ophakamileyo. 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 engqongileyo zibandakanya: ukucoceka okuphezulu kwigumbi lokuhlambela, uthuli olungenathuli kwigumbi lokugquma, njl njl. Kwezinye iindawo, ukufuma komoya kuphezulu kakhulu, ngoko ke ngaphambi kokutyalwa, akufuneki kuphela ukucoca amacandelo kwi-substrate kunye negumbi lokucoca, kodwa kufuneka kwakhona ukwenza umsebenzi wokubhaka kunye nokukhupha amanzi. Ukongezelela, ukwenzela ukukhusela ioli ekungeneni kwigumbi lokucoca, kuyafuneka kwakhona ukuba ubeke ingqalelo kwi-oyile yokubuyisela kunye nemilinganiselo yokuthintela ioli yepompo yokusasaza i-refueling.
