Hauv kev lag luam xws li microelectronics, optoelectronics thiab biopharmaceuticals,qaim annealing(BA), pickling lossis passivation (AP),electrolytic polishing (EP)thiab nqus tsev kho mob theem nrab feem ntau yog siv rau high-purity thiab huv si pipeline systems uas kis rhiab heev los yog corrosive media. Dissolved (VIM + VAR) cov khoom.
A. Electro-Polished (Electro-Polished) yog hu ua EP. Los ntawm electrochemical polishing, qhov chaw morphology thiab cov qauv tuaj yeem txhim kho tau zoo, thiab qhov tseeb ntawm qhov chaw tuaj yeem raug txo kom tsawg. Qhov saum npoo yog kaw, tuab chromium oxide zaj duab xis, lub zog yog nyob ze rau qib qub ntawm cov hlau, thiab cov xov xwm raug txo qis - feem ntau haum rau qib hluav taws xob.high-purity gases.
B. Bright Annealing (Bright Annealing) yog hu ua BA. Kev kho cua kub kub hauv hydrogenation lossis lub tshuab nqus tsev, ntawm ib sab, tshem tawm cov kev ntxhov siab sab hauv, thiab ntawm qhov tod tes, tsim cov yeeb yaj kiab passivation ntawm cov yeeb nkab los txhim kho cov qauv morphological thiab txo qis zog, tab sis tsis nce qhov roughness - feem ntau haum rau GN2 , CDA, thiab tsis yog txheej txheem inert gases.
C. Pickled & Passivated / Chemically Polished (Pickled & Passivated / Chemically Polished) yog hu ua AP thiab CP. Pickling los yog passivation ntawm cov yeeb nkab yuav tsis ua rau kom qhov chaw roughness, tab sis nws muaj peev xwm tshem tawm cov seem nyob rau saum npoo thiab txo lub zog theem, tab sis nws yuav tsis txo tus naj npawb ntawm interlayers - feem ntau yog siv nyob rau hauv industrial qib kav.
D. Nqus theem nrab dissolution huv raj Vim (Nqus Induction Melting) + Var (Nqus ArcRemelting), hu ua V + V, yog ib yam khoom ntawm Sumitomo Hlau tuam txhab. Nws tau raug ua tiav dua nyob rau hauv arc tej yam kev mob nyob rau hauv lub nqus tsev vacuum, uas zoo txhim kho corrosion kuj thiab nto roughness. Degree - feem ntau haum rau corrosive high-purity hluav taws xob qib roj hluav taws xob, xws li: BCL3, WF6, CL2, HBr, thiab lwm yam.
