Warshadaha sida microelectronics, optoelectronics iyo biopharmaceuticals,naaxinta dhalaalaya(BA), pickling ama passivation (AP),polishing electrolytic (EP)iyo daawaynta labaad ee faakuumka ayaa guud ahaan loo isticmaalaa nadiif-sare iyo nidaamyada dhuumaha nadiifka ah ee gudbiya warbaahinta xasaasiga ah ama daxalaysa. Alaabooyinka kala diri (VIM+VAR).
A. Electro-Polished (Electro-Polished) waxa loo yaqaan EP. Iyada oo loo marayo polishing electrochemical, morphology iyo qaab-dhismeedka dusha sare ayaa si weyn loo wanaajin karaa, iyo aagga dhabta ah ee dhabta ah waa la dhimi karaa ilaa xad. Dusha sare waa filim chromium oxide ah oo xiran, qaro weyn, tamartuna waxay ku dhowdahay heerka caadiga ah ee daawaynta, iyo qadarka warbaahinta waa la dhimay - sida caadiga ah waxay ku habboon tahay darajada elektiroonigga ah.gaasas saafi ah oo sarreeya.
B. Bright Annealing (Bright Annealing) waxaa loo tixraacaa BA. Daawaynta kulaylka heerkulka sare ee hydrogenation ama vacuum state, dhinaca kale, waxay baabi'isaa walbahaarka gudaha, iyo dhinaca kale, waxay sameeyaan filim passivation dusha sare ee tuubada si loo hagaajiyo qaab-dhismeedka morphological iyo in la yareeyo heerka tamarta, laakiin ma aha. kordhiyaan qallafsanaanta dusha sare - badiyaa ku habboon GN2, CDA, iyo gaasas aan shaqaynayn.
C. La miiray & Baasaboor/Kimiko la miiray (la soo guray oo la baastay/kiimikada la miiray) waxaa loo tixraacaa AP iyo CP. Qaadista ama bakhtiinta tuubada ma kordhin doonto qallafsanaanta dusha sare, laakiin waxay ka saari kartaa qaybaha haray ee dusha sare waxayna yareyn kartaa heerka tamarta, laakiin ma dhimi doonto tirada isku-dhafka - inta badan loo isticmaalo tuubooyinka darajada warshadaha.
D. Vacuum kala dirida sare ee nadiifka ah tuubo nadiif ah Vim (Vacuum Induction Melting) + Var (Vacuum ArcRemelting), oo loo yaqaan V+V, waa wax soo saarka Sumitomo Metal Company. Waxaa mar kale lagu farsameeyay xaaladaha arc ee xaalad faaruq ah, taas oo si wax ku ool ah u wanaajisa iska caabinta daxalka iyo qallafsanaanta dusha sare. Degree – caadi ahaan ku habboon gaasaska darajada elektiroonigga ah ee nadiifka ah ee aadka u wasakhaysan, sida: BCL3, WF6, CL2, HBr, iwm.
