Titanium tawg los ntawm "oxygen", uas tsis tshua muaj nqi tsim khoom kom tau txais kev tawg tshiab

Nyob rau hauv lub ntiaj teb loj heev ntawm cov ntaub ntawv science, titanium, nrog nws cov cim lub cev thiab tshuaj lom neeg, tau ntev ua lub hnub qub keeb hauv kev tshawb fawb thiab kev lag luam. Txawm li cas los xij, titanium txoj kev nyob ze nrog cov pa oxygen yog ib qho tseem ceeb ntawm kev txwv nws daim ntawv thov dav. Hmoov zoo, nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, qhov nyuaj no tau maj mam tawg. Tsis ntev los no, University of Tokyo, Nyiv, cov xov xwm zoo siab - lawv tau ua tiav kev tsim cov titanium yaj ncaj qha kev tsim cov pa oxygen tsawg ntawm titanium txiav-ntug thev naus laus zis, uas tsis yog tsuas yog ua rau muaj kev vam meej hauv titanium ua technology, ntau titanium kev lag luam yav tom ntej kev loj hlob. depicts ib daim ntawv loj.
Titanium, raws li lub teeb yuag, muaj zog thiab tshuaj tiv thaiv cov khoom, muaj ntau yam kev siv hauv aerospace, cov khoom siv kho mob, cov tsheb loj thiab lwm yam haujlwm. Txawm li cas los xij, tus nqi siab ntawm kev rho tawm cov pa oxygen los ntawm titanium ore tau khaws cov nqi ntawm cov khoom siv titanium ntshiab siab, txwv kev nthuav dav ntawm nws daim ntawv thov. Txhawm rau daws qhov teeb meem no, cov kws tshawb fawb ntawm University of Tokyo's Institute of Industrial Science tau ua haujlwm tau ntau xyoo los tsim ib txoj hauv kev tshiab uas txo tus nqi ntawm kev tsim cov pa oxygen titanium tsawg.

Lub hauv paus ntawm txoj kev no yog ib qho kev siv tshuab tshiab raws li cov hlau tsis tshua muaj hauv ntiaj teb. Los ntawm reacting molten titanium nrog yttrium hlau thiab cov khoom zoo sib xws xws li yttrium trifluoride, cov kws tshawb fawb tau ua tiav hauv kev tshem tawm cov pa oxygen ntawm titanium mus rau qib qis heev ntawm 0.02 feem pua ​​ntawm ib pawg. Hauv cov txheej txheem no, yttrium txuas nrog oxygen los tsim lub ntiaj teb tsis tshua muaj halide oxide, uas ua tiav qhov txo qis hauv cov ntsiab lus oxygen ntawm titanium yaj. Txawm tias zoo siab dua, lub reacted yttrium tuaj yeem rov ua dua, txo cov nqi ntau lawm.
Kev tawg ntawm cov thev naus laus zis no tsis yog tsuas yog nyob rau hauv nws tus nqi qis, tab sis kuj nyob rau hauv nws txoj kev cia siab rau kev siv dav. Ua ntej, vim qhov txo qis ntawm cov nqi tsim khoom, cov tuam ntxhab tuaj yeem siv ntau yam khoom zoo ntawm titanium los tsim cov khoom lag luam zoo thiab cov khoom zoo. Thib ob, thev naus laus zis kuj tseem tsim nyog rau kev ua cov khoom siv titanium uas muaj cov pa oxygen ntau, ntxiv rau qhov chaw ntawm cov ntaub ntawv titanium. Thaum kawg, qhov yooj yim thiab kev ua haujlwm siab ntawm cov thev naus laus zis ua rau nws muaj txiaj ntsig zoo rau cov ntawv thov kev lag luam, thiab nws xav tias yuav ua rau kev txhim kho tshiab hauv kev lag luam titanium yav tom ntej.
Txawm hais tias cov cuab yeej no tam sim no muaj qee qhov kev txwv, xws li cov khoom siv deoxidized titanium muaj qee qhov nyiaj ntawm yttrium, uas yuav muaj kev cuam tshuam rau cov khoom siv thiab tshuaj lom neeg ntawm titanium alloys. Txawm li cas los xij, cov kws tshawb fawb tau hais tias lawv tab tom nrhiav kev daws teeb meem, nrog rau kev pom kom daws tau qhov teeb meem yav tom ntej. Thaum qhov teeb meem ntawm yttrium contamination raug daws, lub tshuab yuav tsum tau siv dav hauv kev tsim khoom, txhaj tshuaj tshiab rau hauv kev tsim kho ntawm titanium kev lag luam.
Txoj kev tsim khoom qis qis tshiab no tsim los ntawm cov kws tshawb fawb tsis yog tsuas yog rhuav tshem cov txheej txheem ntawm cov nqi tsim khoom titanium xwb, tab sis tseem ua rau txoj hauv kev rau kev siv dav dav ntawm cov ntaub ntawv titanium. Peb muaj laj thawj ntseeg tias yav tom ntej, titanium yuav qhia nws qhov tshwj xeeb ntxim nyiam thiab muaj txiaj ntsig hauv ntau thaj chaw, thiab ua kom muaj txiaj ntsig ntau dua rau kev txhim kho ntawm tib neeg lub neej.
