Kub tiv thaiv Niobium hais

Los ntawm saum npoo si daim txheej (xws li nbsi ₂) lossis alloying (xws li niobium}} {{{{{} Cov yam ntxwv no ua rau nws yog cov khoom siv ntxiv rau cov foob pob hluav taws Ib txhij siv los ua cov rwb thaiv tsev thaiv cov txheej rau molten ntsev reflectors, tiv taus rau 800℃c fluoride ntsev corrosion thiab thermal poob siab.
Lub purity ntawm niobium hais yog ntau dua los yog sib npaug ntawm 99.95%, nrog kev tswj nruj dhau ntawm oxygen (O<500ppm) and nitrogen (N<100ppm) content, and possessing low neutron absorption cross section (1.1 bar) and radiation damage resistance (>5 dpa). Cov yeeb yaj kiab no muaj feem xyuam rau cov cas tiv thaiv ntawm qhov chaw nuclear lub zog, ua haujlwm ntev ootope thermoelectric cov tshuab hluav taws xob hauv cov chaw nyob hauv Irradiation; Nws tseem siv rau thawj lub cuab yeej siv phab ntsa txheej ntawm cov khoom siv fusion li tiv thaiv cov ntshav irradiation yision.

• Kev Kho Mob Ua Ke

Ntxiv cov ntsiab xws li tungsten (W), HF), zirconium (xws li NB-10ZR), thiab ua kom muaj kev sib xyaw ua ke los ntawm lub tshuab nqus tsev arc melting (var).
2, hmoov acting txheej txheem

• Plasma Atomization (PA)

Alloy niobium ingots are melted into liquid droplets by a plasma torch under an inert atmosphere, and after cooling, they form high sphericity (>95%) cov lus nrog cov me me muaj ntau ntawm 15-150 μ m.

• Hydrogenated dehydrogenation (HDH)

Niobium Ingots yog crushed tom qab hydrogen embrittlement ntawm cov khoom siv hluav taws xob siab, thiab tom qab ntawd ua kom lub tshuab nqus tsev nrog tus nqi qis dua tab sis me ntsis siab dua oxygen cov ntsiab lus.

• Mechanical Ntsuam Xyuas thiab Kev Kawm

Los ntawm kev siv kev ntsuam xyuas thiab siv dav hlau siv dav hlau, cov particle loj tuaj yeem raug tswj hwm yog qhov tseeb (xws li 15-53 μ m rau addecting kev tsim khoom).
3, Kev Kho Mob Dua Li Nto

• Kev npaj ntawm silight

Chemical Vapor Deposition (CVD) yog siv los tsim Nbsi ₂ lossis Mosi ₂ txheej txheem (tuab oxidation tsis kam ntawm 600℃c txog 1400℃C.

• Nqus cua sov kho cua sov

Ua diffusion annaling hauv lub tshuab nqus tsev ib puag ncig 1200 {{100}} 1400} 1400℃c los txhim kho cov nplaum ntawm cov nplaum thiab cov ntaub qhwv thiab tsis txhob muaj qhov kub thiab txias.

• passivation

Txo cov npoo av (RA<0.5 μ m) and minimize stress concentration in high-temperature environments through electrolytic polishing or chemical polishing.
4, Kev sim tshuaj thiab tswj kev tswj hwm zoo

• Xeem Ntawv

Particle loj tso cai (Laser Differaction txoj kev), sphericity (duab analyzer), willowmeter (high flatmeter);
Qiv ntom ntom ntom ntom (ntau dua lossis sib npaug rau 4.5 g / cm ³) thiab khav theeb nrhiav kom tau.

• Tshuaj Lom Neeg Tshuaj Ntsuam

Kev ntsuas ntawm O thiab n cov ntsiab lus siv cov pa oxygen thiab nitrogen analyzer (O<500ppm, N<100ppm);
ICP - ms kuaj pom kev sib txuam ntawm alloyterter faib.

• Kev ntsuas qhov kub thiab txias

1400 DEGree C Oxidation Test (Oxidation Qhov hnyav nce<1 mg/cm ² · h);
Kev ntsuas kub kub thiab txias thiab nkag mus rau hauv qhov ncauj<1% at 1000 ° C/100h).
