Mumaindasitiri akadai sema microelectronics, optoelectronics uye biopharmaceuticals,kupenya kwakajeka(BA), kusvina kana kupfava (AP),kukwesha kwemagetsi (EP)uye mushonga wevacuum secondary zvinowanzo shandiswa kumapaipi akachena uye akachena anotumira zvinhu zvinokuvadza kana zvinopisa. Zvigadzirwa zvakanyungudutswa (VIM+VAR).
A. Electro-Polished (Electro-Polished) inonzi EP. Kuburikidza ne electrochemical polishing, chimiro chepamusoro uye chimiro zvinogona kuvandudzwa zvakanyanya, uye nzvimbo chaiyo yepamusoro inogona kuderedzwa kusvika pamwero wakati. Pamusoro payo ifirimu rakavharwa, gobvu re chromium oxide, simba riri pedyo nechiyero chenguva dzose che alloy, uye huwandu hwe media hunoderedzwa - kazhinji hwakakodzera giredhi remagetsi.magasi akachena kwazvo.
B. Bright Annealing (Bright Annealing) inonzi BA. Kurapa kupisa kwakanyanya muhydrogenation kana vacuum state, kune rumwe rutivi, kunobvisa kushushikana kwemukati, uye kune rumwe rutivi, kunogadzira firimu repassivation pamusoro pepombi kuti ivandudze chimiro che morphological uye kuderedza simba, asi haiwedzere kuomarara kwepamusoro - kazhinji yakakodzera GN2, CDA, uye magasi asina process inert.
C. Kupisa & Kupwanya/Kuporiswa Nemakemikari (Kupisa & Kupwanya/Kuporiswa Nemakemikari) kunonzi AP neCP. Kupisa kana kupwanya pombi hakuzowedzera kuomarara kwepanzvimbo, asi kunogona kubvisa zvidimbu zvasara pamusoro uye kuderedza simba, asi hazvizoderedzi huwandu hwezvikamu zvinopindirana - zvinowanzoshandiswa mumapombi emhando yepamusoro.
D. Chubhu yakachena yekubvisa ngura yeVim (Vacuum Induction Melting) + Var (Vacuum ArcRemelting), inonzi V+V, inogadzirwa neSumitomo Metal Company. Yakagadziriswazve pasi pemamiriro e arc mu vacuum state, izvo zvinovandudza kuramba ngura uye kuomarara kwenzvimbo. Dhigirii - inowanzo shandiswa kumagasi emagetsi ane hunyoro hwakawanda, akadai se: BCL3, WF6, CL2, HBr, nezvimwewo.
