Hauv kev lag luam xws li microelectronics, optoelectronics thiab biopharmaceuticals,ci ntsa iab(BA), pickling los yog passivation (AP),Kev sib tsoo electrolytic (EP)thiab kev kho mob theem ob ntawm lub tshuab nqus tsev feem ntau yog siv rau cov kav dej uas muaj kev ntshiab thiab huv si uas xa cov xov xwm rhiab heev lossis corrosive. Cov khoom yaj (VIM + VAR).
A. Electro-Polished (Electro-Polished) yog hu ua EP. Los ntawm electrochemical polishing, qhov morphology ntawm qhov chaw thiab cov qauv tuaj yeem txhim kho tau zoo heev, thiab qhov chaw tiag tiag tuaj yeem txo qis rau qee qhov. Qhov chaw yog ib zaj duab xis chromium oxide kaw, tuab, lub zog ze rau qib ib txwm ntawm cov hlau, thiab qhov ntau ntawm cov xov xwm raug txo qis - feem ntau yog tsim rau qib hluav taws xob.cov pa roj purity siab.
B. Kev Kho Kom Ci Ntxoov Ntxoo (Bright Annealing) yog hu ua BA. Kev kho cua sov kub siab hauv hydrogenation lossis lub xeev nqus tsev, ntawm ib sab tes, tshem tawm kev ntxhov siab sab hauv, thiab ntawm qhov tod tes, tsim cov zaj duab xis passivation rau ntawm qhov chaw ntawm cov yeeb nkab kom txhim kho cov qauv morphological thiab txo qib zog, tab sis tsis ua rau qhov roughness ntawm qhov chaw - feem ntau haum rau GN2, CDA, thiab cov pa roj inert uas tsis yog txheej txheem.
C. Pickled & Passivated/Chemically Polished (Pickled & Passivated/Chemically Polished) yog hu ua AP thiab CP. Pickling lossis passivation ntawm cov yeeb nkab yuav tsis ua rau qhov roughness ntawm qhov chaw nce ntxiv, tab sis nws tuaj yeem tshem tawm cov khoom seem ntawm qhov chaw thiab txo qib zog, tab sis nws yuav tsis txo cov naj npawb ntawm cov interlayers - feem ntau yog siv rau hauv cov yeeb nkab qib kev lag luam.
D. Lub raj nqus tsev thib ob uas yaj hauv lub tshuab nqus tsev Vim (Nqus Tsev Induction Melting) + Var (Nqus Tsev ArcRemelting), hu ua V+V, yog ib yam khoom ntawm Sumitomo Metal Company. Nws tau ua tiav dua hauv qab arc hauv lub xeev nqus tsev, uas ua rau zoo dua qhov kev tiv thaiv corrosion thiab qhov roughness ntawm qhov chaw. Qib - feem ntau haum rau cov pa roj hluav taws xob uas muaj corrosive heev, xws li: BCL3, WF6, CL2, HBr, thiab lwm yam.
