Kumashishini afana ne-microelectronics, i-optoelectronics kunye ne-biopharmaceuticals,ukukhanya okuqaqambileyo(BA), pickling okanye passivation (AP),ukuguliswa kwe-electrolytic (EP)kunye nonyango lwesibini lwe-vacuum lusetyenziselwa ukucoceka okuphezulu kunye neenkqubo zemibhobho ecocekileyo ezihambisa i-media media e-ecrosive or corrosion. Iimveliso ezichithwe (VIM + VAR).
A. I-Electro-Polished (i-Electro-Polished) ibizwa ngokuba yi-EP. Ngokusebenzisa i-electrochemical polishing, i-morphology yomhlaba kunye nesakhiwo sinokuphuculwa kakhulu, kwaye indawo yangempela yomhlaba ingancitshiswa ukuya kwinqanaba elithile. Umphezulu yifilimu evaliweyo, etyebileyo yechromium oxide, amandla asondele kwinqanaba eliqhelekileyo le-alloy, kwaye umthamo wemidiya uyancitshiswa - ngokuqhelekileyo ulungele ibakala lombane.iigesi ezicocekileyo.
B. Bright Annealing (Bright Annealing) kubhekiselwa kuko njengeBA. Ubushushu obuphezulu bonyango kwi-hydrogenation okanye i-vacuum state, kwelinye icala, kuphelisa uxinzelelo lwangaphakathi, kwaye ngakolunye uhlangothi, yenza ifilimu yokugqithisa phezu kombhobho wokuphucula ukwakheka kwe-morphological kunye nokunciphisa izinga lamandla, kodwa ayenzi. ukwandisa uburhabaxa bomphezulu - ngokuqhelekileyo ilungele i-GN2, i-CDA, kunye ne-non-process inert gases.
C. Pickled & Passivated/Chemically Polished (Pickled & Passivated/Chemically Polished) zibizwa ngokuba yi-AP kunye ne-CP. I-Pickling okanye i-passivation yombhobho ayiyi kwandisa ubuninzi bomhlaba, kodwa inokususa amaqhekeza asele phezu komhlaba kwaye inciphise izinga lamandla, kodwa ayiyi kunciphisa inani le-interlayers - ngokuqhelekileyo isetyenziswe kwimibhobho yomgangatho wezoshishino.
D. I-vacuum yesibini yokuchithwa kwe-tube ecocekileyo i-Vim (i-Vacuum Induction Melting) + i-Var (i-Vacuum ArcRemelting), ebizwa ngokuba yi-V + V, iyimveliso ye-Sumitomo Metal Company. Icutshungulwe kwakhona phantsi kweemeko ze-arc kwimeko ye-vacuum, ephucula ngokufanelekileyo ukuxhatshazwa kwe-corrosion kunye nobunzima bomhlaba. I-Degree - idla ngokufanelekileyo kwi-corrosive high-purity electronic grade gases, ezifana ne-BCL3, WF6, CL2, HBr, njl.
