High Purity Niobium Tube

Lub tshuab nqus tsev brazing txoj kev rau kev tsim lub siab purity niobium raj thiab stainless hlau raj muaj cov kauj ruam hauv qab no:

1. Tus qub raug kho, thiab tom kawg yog electroplated nrog Nickel tom qab pretreatment.

2. Stainless hlau raj yog teem rau sab nraud ntawm high-purity niobium raj thiab stainless hlau hauv ob sab phlu yog teem rau sab hauv ntawm nws.

3. Lub voj voos voos yog teem rau ntawm qhov chaw sib cuag ntawm ob sab, thiab cov hlua ntawm AgCu20 coated nrog titanium hmoov yog muab tso rau hauv daim duab peb sab zawj, thiab tom qab ntawd lub tshuab nqus tsev brazing yog nqa tawm hauv lub tshuab nqus tsev brazing rauv.

4. Tom qab lub tshuab nqus tsev brazing tiav lawm, cov txheej txheem stainless hlau raug tshem tawm kom paub qhov vuam.

5. Lub tshuab nqus tsev brazing tsis tuaj yeem tsuas yog ua kom cov khoom ntim puv nkaus xwb tab sis kuj ua kom cov vuam huv huv thiab tsis txhob oxidation ntawm niobium phaj hauv cov txheej txheem cua sov dov, qhov teeb meem ntawm kev hloov NB-TI flanges nrog stainless hlau flanges vim qhov sib txawv loj ntawm ob lub Coefficient ntawm thermal expansion yog kov yeej, yog li daws qhov teeb meem ntawm lub tshuab nqus tsev sealing ntawm superconducting kab noj hniav.

Txoj kev tsim khoom belongs rau kev ua haujlwm ntawm superconducting accelerating kab noj hniav. Tam sim no, cov khoom nyiam tshaj plaws rau kev siv cov kab noj hniav superconducting yog cov hlau niobium, uas muaj qhov tseem ceeb tshaj plaws (9.26 K), qhov siab tshaj plaws superheat teb (kwv yees 200 MT), thiab cov cuab yeej zoo heev raws li kev faib Superconductor, tshwj xeeb tshaj yog tsim nyog. rau machining rau ntau yam duab ntawm lub superconducting kab noj hniav. High purity niobium raj-316L tau dhau los ua qhov kev thov ceev rau kev ua haujlwm siab ntawm cov kab noj hniav thiab tus nqi.

Vim tias qhov sib txawv loj hauv kev nthuav dav coefficient ntawm ob lub hlau, txoj kev vuam siv tau yooj yim los tsim cov khoom tawg thiab ua rau lub tshuab nqus tsev. AGÓN lub teb chaws kuaj tau ua tiav siv lub tshuab nqus tsev vacuum los txuas rau ob. Lub chaw soj nstuam siv cov tooj liab tsis muaj pa oxygen ua cov khoom muab tub lim, txawm li cas los xij, muaj Fe-Nb cov khoom sib txuas ntawm qhov chaw vuam, uas ua rau txo qis hauv vuam lub zog thiab tuaj yeem nqus tau. Vim tias qhov kub thiab txias ua haujlwm ntawm cov khoom siv vuam yog kua helium kub (4.2 K), nws yuav tsum tau nyiaj ntau lub sij hawm ntawm txias thiab kub shocks los ntawm 4.2 K mus rau 873 K thiab txaus txhua yam muaj zog, cov saum toj no cov kev cai yuav tsum tau muab tso rau siab heev cov kev cai rau lub brazing seam ntawm ob qhov chaw.

Lawv tau siv los ua cov ntaub ntawv hauv paus, thiab titanium hmoov coated AGCU20 solder tau siv los ua cov khoom siv, "High purity niobium tube" koom nrog RRR tus nqi (qhov piv ntawm kev tiv thaiv ntawm 300K rau resistivity ntawm 10K) ntau dua 300 thiab thickness ntau dua. mas 3mm. 316L stainless hlau raj rau lub tshuab nqus tsev flange.
