Mu mafakitale monga ma microelectronics, optoelectronics ndi biopharmaceuticals,kuwala kowonjezera(BA), pickling kapena passivation (AP),kupukuta kwamagetsi (EP)ndi mankhwala ena ochotsera mpweya nthawi zambiri amagwiritsidwa ntchito pa mapaipi oyera komanso oyera omwe amafalitsa zinthu zobisika kapena zowononga. Zinthu zosungunuka (VIM+VAR).
A. Yopukutidwa ndi Maginito (Yopukutidwa ndi Maginito) imatchedwa EP. Kudzera mu kupukuta kwa maginito, mawonekedwe ndi kapangidwe ka pamwamba zimatha kukonzedwa bwino, ndipo malo enieni a pamwamba amatha kuchepetsedwa kufika pamlingo winawake. Pamwamba pake ndi filimu yotsekedwa, yokhuthala ya chromium oxide, mphamvu yake ili pafupi ndi mulingo wabwinobwino wa alloy, ndipo kuchuluka kwa zinthu zolumikizira kumachepetsedwa - nthawi zambiri kumakhala koyenera kugwiritsa ntchito electron grade.mpweya woyera kwambiri.
B. Bright Annealing (Bright Annealing) imatchedwa BA. Kutenthetsa kutentha kwambiri mu hydrogenation kapena vacuum state, kumbali imodzi, kumachotsa kupsinjika kwamkati, ndipo kumbali ina, kumapanga filimu yodutsa pamwamba pa chitoliro kuti ikonze kapangidwe kake ka morphological ndikuchepetsa mphamvu, koma sikuwonjezera kukhwima kwa pamwamba - nthawi zambiri kumakhala koyenera GN2, CDA, ndi mpweya wopanda ntchito.
C. Kusakaniza ndi Kusakaniza/Kupukuta ndi Mankhwala (Kusakaniza ndi Kusakaniza/Kupukuta ndi Mankhwala) kumatchedwa AP ndi CP. Kusakaniza kapena kupukuta ndi madzi sikudzawonjezera kuuma kwa pamwamba, koma kungachotse tinthu totsala pamwamba ndikuchepetsa mphamvu, koma sikudzachepetsa kuchuluka kwa zigawo zolumikizirana - zomwe nthawi zambiri zimagwiritsidwa ntchito m'mapaipi apamwamba a mafakitale.
D. Chitoliro choyeretsera cha Vacuum secondary dissolving clean chubu Vim (Vacuum Induction Melting) + Var (Vacuum ArcRemelting), chomwe chimatchedwa V+V, ndi chinthu chopangidwa ndi Sumitomo Metal Company. Chakonzedwanso pansi pa mikhalidwe ya arc mu vacuum state, zomwe zimapangitsa kuti kukana dzimbiri kukhale bwino komanso kusakhazikika pamwamba. Degree - nthawi zambiri imakhala yoyenera kupopera mpweya wamagetsi woyera kwambiri, monga: BCL3, WF6, CL2, HBr, ndi zina zotero.
