Ib qho ntawm cov ntsiab lus siv ntawm Lanthhan thiab Cerium hlau nyob hauv kev tsim khoom ntawm lub ntiaj teb tsis tshua muaj cov hlau thiab lub teeb yuag. Qhov sib ntxiv ntawm LA-CE txheej txheem txhim kho cov khoom siv cov tshuab ntawm cov ntaub ntawv no, ua rau muaj zog thiab ua rau muaj zog ntxiv. Qhov no yog tau txais txiaj ntsig tshwj xeeb tshaj plaws rau kev lag luam uas xav tau lub teeb yooj yim tseem muaj cov ntaub ntawv muaj zog, xws li aerospace thiab kho tsheb. LA-CE alloys tseem siv nyob rau hauv tsawg-lub ntiaj teb magnesium-txhuas me ntsis alloys uas nyhav yog qhov hnyav txo yog qhov tseem ceeb tsis muaj kev ua tau zoo.

Sib xyaw tsis tshua muaj lub ntiaj teb ruaj khov cov hlau nplaum cov ntaub ntawv

Lanthhanum-Alloy Nkaus ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov hlau nplaum tsis tshua muaj cov khoom siv tsis tshua muaj. Cov hlau nplaum yog qhov tseem ceeb hauv ntau cov ntawv thov, suav nrog cov tshuab hluav taws xob, cov tshuab hluav taws xob thiab kev sib nqus Revoning kev kuaj (MRI). Ntxiv cov ntawv sau LA-CE rau cov khoom siv no ua rau lawv cov khoom sib nqus muaj zog, ua rau lawv tau txais txiaj ntsig ntau dua thiab siv tau hauv lawv cov ntawv thov.

Kev Ua Haujlwm Siab Hydrogen Cia Alloy

Lwm qhov kev cog lus thov rau Lanthanum-Cerium alloys yog hauv hydrogen cia. Lub alloy yog siv los tsim cov kev ua tau zoo uas tsis tshua muaj muaj txiaj ntsig Raws li lub ntiaj teb hloov mus rau lub zog huv si, qhov xav tau ntawm hydrogen txuag cov kev khaws cia kom nce. Cov khoom ntawm LA-CE cov neeg sib tw ua rau lawv zoo tshaj plaws rau kev txhim kho hydrogen cia ntawm kev khaws cia zoo thiab tso hydrogen.

Lub neej yav tom ntej kev cia siab ntawm cov rwb thaiv tsev thermal thiab cov khoom siv thermal

Lanthhanum-cerium alloys muaj cov kev siv yuav dhau ntawm lawv cov kev siv tam sim no. Cov kws tshawb nrhiav raug tshawb nrhiav nws cov peev txheej hauv rwb thaiv tsev thiab cov ntawv thov thermal cia. Cov khoom tshwj xeeb ntawm LA-CE alloys tuaj yeem pab txhawb kev txhim kho cov ntaub ntawv ntawm cov kub ua tau zoo, ua rau lub zog txuag kev tsim kho thiab kev siv khoom lag luam. Tsis tas li ntawd, nws lub peev xwm ua kom muaj peev xwm siv tau rau cov ntawv thov hauv cov khoom siv hluav taws xob txuas ntxiv yog qhov tseem ceeb.

Hauv kev xaus

Hauv cov ntsiab lus, lanthhanum-cerium (LA-CE) Alloy Hlau yog cov khoom siv ntau ntau nrog ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau qhov kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau qhov kev lag luam hauv ntau qhov kev lag luam. Nws cov hluav taws xob zoo, cov khoom sib nqus thiab kho qhov muag ua rau siv rau hauv lub ntiaj teb tsis tshua muaj alloys, tas mus li hlau nplaum thiab hydrogen cia lub tshuab. Raws li kev tshawb fawb txuas ntxiv mus txiav tawm cov ntawv thov tshiab, LA-CE alloys yuav tsum ua lub luag haujlwm tseem ceeb hauv kev tsav tsheb thev naus laus zis thiab txhawb nqa kev txhim kho kom zoo dua qub yav tom ntej. Kev tshawb nrhiav txuas ntxiv hauv nws lub peev xwm hauv insulating thiab cov khoom siv thermal cia tseem ceeb nyob rau hauv cov khoom siv hloov zuj zus. Nyob rau tib lub sijhawm, cov lus qhia Cerium muaj cov khoom siv hauv tsev, cov khoom siv hluav taws xob, tsis tshua muaj cov ntaub ntawv ntawm lub ntiaj teb, tsis tshua muaj lub ntiaj teb lub ntiaj teb ceramics thiab lwm cov ntaub ntawv tshiab.
