M'mafakitale monga ma microelectronics, optoelectronics ndi biopharmaceuticals,kuwala kowala(BA), pickling kapena passivation (AP),electrolytic polishing (EP)komanso chithandizo chachiwiri cha vacuum nthawi zambiri chimagwiritsidwa ntchito poyeretsa kwambiri komanso kuyeretsa mapaipi omwe amafalitsa zinthu zovutirapo kapena zowononga. Zida zosungunuka (VIM + VAR).
A. Electro-Polished (Electro-Polished) imatchedwa EP. Kupyolera mu electrochemical kupukuta, morphology pamwamba ndi kapangidwe akhoza bwino kwambiri, ndipo kwenikweni pamwamba dera akhoza kuchepetsedwa kumlingo wakutiwakuti. Pamwambapo ndi filimu yotsekedwa, yochuluka ya chromium oxide, mphamvu ili pafupi ndi mlingo wamba wa alloy, ndipo kuchuluka kwa zofalitsa kumachepetsedwa - nthawi zambiri kumakhala koyenera pamagetsi.mpweya wabwino kwambiri.
B. Bright Annealing (Bright Annealing) amatchedwa BA. Kutentha kwapamwamba kwa kutentha kwa hydrogenation kapena vacuum state, kumbali imodzi, kumathetsa nkhawa zamkati, ndipo kumbali ina, kumapanga filimu ya passivation pamwamba pa chitoliro kuti apititse patsogolo mapangidwe a morphological ndi kuchepetsa mphamvu, koma kuonjezera roughness pamwamba - nthawi zambiri oyenera GN2, CDA, ndi sanali ndondomeko mpweya inert.
C. Pickled & Passivated/Chemically polished (Pickled & Passivated/Chemically Polished) amatchedwa AP ndi CP. Pickling kapena passivation ya chitoliro sichidzawonjezera kuuma kwa pamwamba, koma ikhoza kuchotsa tinthu tating'ono tating'ono pamwamba ndi kuchepetsa mphamvu ya mphamvu, koma sikungachepetse chiwerengero cha interlayers - zomwe zimagwiritsidwa ntchito m'mapaipi a mafakitale.
D. Vacuum secondary dissolution clean tube Vim (Vacuum Induction Melting) + Var (Vacuum ArcRemelting), yotchedwa V + V, ndi mankhwala a Sumitomo Metal Company. Idakonzedwanso pansi pamikhalidwe ya arc mu vacuum state, yomwe imathandizira bwino kukana dzimbiri komanso kuuma kwa pamwamba. Digiri - nthawi zambiri yoyenera kuwononga kwambiri mpweya wamagetsi wamagetsi, monga: BCL3, WF6, CL2, HBr, etc.
