Raws li qhov tseeb tias cov ntshiab titanium thiab TiZr series muaj qhov sib npaug siab ntawm adsorbed hydrogen, muaj peev xwm txhim kho helium, thiab tsim hydride muaj cov khoom siv tshuaj lom neeg ruaj khov thiab kev nyab xeeb siab, nws tuaj yeem siv rau lub sijhawm ntev cia ntawm tritium roj, thiab Qhov teeb meem tseem ceeb uas yuav tsum tau daws yog txo qhov kev tuav pov hwm; Raws li qhov siab desorption hydrogen tshuav nyiaj li cas siab ntawm TiFe system thiab TiMn system, nws tuaj yeem tsim thiab kawm txog hydrogen cia thiab siv hauv cov txheej txheem tsim khoom. Qhov teeb meem tseem ceeb uas yuav tsum tau daws yog kom paub txog qhov rov ua dua ntawm cov ntaub ntawv thiab txo cov nqi.
Yuav kom daws tau cov teeb meem saum toj no, cov kev taw qhia kev tshawb fawb tam sim no feem ntau yog hloov pauv. Nws cia siab tias los ntawm kev tshawb fawb ntawm ternary los yog multicomponent alloying, hydrogen absorption thiab desorption thiab tag nrho cov khoom ntawm multicomponent alloys yuav tawg los ntawm.
1, Ntshiab Titanium
Piv nrog rau lwm cov ntaub ntawv, titanium muaj kev ua tau zoo heev hauv hydrogen cia. Ua ntej, titanium muaj qhov zoo ntawm adsorption sai thiab desorption ntawm hydrogen. Tsis tas li ntawd, qhov sib npaug siab ntawm adsorbed hydrogen ntawm titanium ntawm chav tsev kub (25 degree) yog 10-8 PA, thiab qhov poob ntawm hydrogen yog txo vim qhov qis adsorption equilibrium siab; Thib ob, hais txog kev nyab xeeb, titanium hydrogen compounds ruaj khov heev. Txawm hais tias raug huab cua ntawm chav tsev kub, lawv yooj yim los tuav. Tshwj tsis yog tias qhov kub siab yog thov, hydrogen yuav tsis raug tso tawm; Thaum kawg, titanium yog cov hlau tsis tshua muaj nqi. Titanium yog nplua nuj nyob rau hauv natural resources. Nws cov ntsiab lus nyob rau hauv lub ntiaj teb pob zeb yog 5 npaug ntawm hlau thiab 100 npaug ntawm tooj liab.
Lub ntsiab qhov tsis zoo ntawm titanium hydrogen cia yog qhov desorption kub ntawm titanium hydride siab dhau lawm thiab khaws cia loj. Txhawm rau kom ncav cuag qhov sib npaug ntawm hydrogen siab ntawm 100KPA, nws yuav tsum tau muab tso rau hauv qhov kub ntawm 800 degrees.
2, TiFe system
TiFe series alloy yog ib hom hydrogen cia khoom nrog kev ua tau zoo, thiab nws kuj yog ib hom AB-hom hydrogen cia alloy. Xyoo 1974, nws tau pom los ntawm Reilly thiab Wiswell ntawm Tebchaws Meskas. Raws li cov khoom siv hydrogen cia, TiFe alloy tau maj mam tau txais kev saib xyuas los ntawm cov kws tshawb fawb thiab tau ua ntau yam kev tshawb fawb.
Tom qab ua kom tiav, TiFe series alloy muaj qhov zoo ntawm hydrogen nqus thiab desorption kev ua tau zoo, thiab nws cov hydrogen nqus thiab desorption muaj peev xwm loj, nrog rau qhov siab tshaj plaws hydrogen nqus peev xwm ntawm (feem ntau), thiab nws adsorption equilibrium hydrogen siab ntawm chav tsev kub yog 300kPa.TiFe alloys. raws li hydrogen cia cov ntaub ntawv muaj ntau qhov zoo, tab sis kuj muaj qee qhov teeb meem: 1) kev ua kom muaj zog yog qhov nyuaj; 2) Kev tuav yog loj.
3, TiZr series
Zr thiab Ti yog pawg Ⅳ B hlau ntsiab. Zoo ib yam li Ti, Zr kuj yog cov khoom siv hlau uas muaj hydrogen nqus ntom ntom. Kev tshawb fawb qhia tau hais tias qhov tsim nyog ti / Zr piv tuaj yeem txhim kho cov khoom ntawm cov hlau; Tsis tas li ntawd, ntxiv cov khoom thib peb ntawm cov hlau M (qhov twg m yog Co, Cr, V, Fe, thiab lwm yam) tuaj yeem txhim kho kev ua haujlwm ntawm hydrogen cia ntawm TiZr. Benvenuti C et al. Qhia tau tias TiZrV muaj qhov ua tau zoo hydrogen nqus tau zoo thiab muaj kev cia siab rau kev siv dav hauv thaj chaw ntawm hydrogen thiab nws cov isotope cia thiab purification.
