Tam sim no daim ntawv thov txheej xwm ntawm titanium alloys nyob rau hauv rail tsheb thauj mus los

Railroad tsheb (Railway Tsheb, RVs) yog ib qho kev thauj mus los uas khiav ntawm txoj kab tsheb ciav hlau. Lawv xa mus rau cov tsheb ciav hlau uas siv cov tsheb ciav hlau lossis tsheb ciav hlau hauv nroog raws li lawv cov chaw khiav haujlwm. Lawv yog tsim los ntawm lub hwj chim systems, braking systems, traction systems thiab lwm yam auxiliary systems. Nws yog cov khoom siv thev naus laus zis engineering nrog cov haujlwm tshwj xeeb uas ua tau raws li cov kev xav tau ntawm kev thauj mus los thiab muaj kev cuam tshuam rau ib puag ncig.

Cov tsheb thauj mus los hauv kev tsheb ciav hlau siv hluav taws xob los ua lub zog thiab feem ntau suav nrog locomotives, cov neeg caij tsheb, tsheb thauj khoom thiab tsheb ciav hlau. Tam sim no, peb lub teb chaws muaj txoj kev tsheb ciav hlau loj tshaj plaws hauv ntiaj teb thiab yog tib lub tebchaws hauv ntiaj teb uas muaj plaub hom kev thauj mus los niaj hnub no: subway, tsheb ciav hlau, tsheb ciav hlau ceev thiab cov neeg caij tsheb tshwj xeeb.
Hauv kev tsheb ciav hlau, cov ntaub ntawv tseem ceeb tshaj plaws tam sim no yog aluminium alloy thiab steel. Ntawm lawv, aluminium alloy yog dav siv hauv tsheb ciav hlau cov ntaub ntawv vim nws qhov zoo xws li lub teeb yuag, siab zog thiab zoo corrosion kuj; steel yog dav siv hauv tsheb lub cev cov ntaub ntawv vim nws qhov zoo xws li lub zog siab thiab zoo corrosion kuj.
Nrog rau kev nrawm ntawm kev loj hlob hauv nroog hauv peb lub tebchaws, kev tsheb ciav hlau hauv nroog tau tsim kho sai, uas tseem tau muab cov kev xav tau siab dua rau cov khoom siv hauv tsheb.
Yog li ntawd, cov ntaub ntawv xws li txhuas alloys thiab steel siv nyob rau hauv lub nroog rail tsheb thauj mus los yuav tsum tau lub teeb yuag tsim rau ib tug tej yam kev mob. Nyob rau hauv xyoo tsis ntev los no, titanium alloys tau siv dav hauv kev tsheb ciav hlau hla kev vim lawv lub zog qis, kev kub siab thiab kub tsis kam thiab lwm yam khoom.
Tshawb nrhiav cov xwm txheej ntawm titanium alloys hauv cov tsheb thauj mus los
Daim ntawv thov ntawm titanium alloys thawj zaug pib thaum xyoo 1940. Vim nws cov txiaj ntsig zoo xws li lub zog siab, lub teeb yuag, thiab kev tiv thaiv corrosion, daim ntawv thov ntawm titanium alloys hauv kev tsheb ciav hlau tsheb ciav hlau feem ntau yog tsom rau hauv traction thiab braking systems.
Nyob rau xyoo 1960, Fabkis cov kws tshawb fawb tau siv cov titanium alloys hauv kev tsheb ciav hlau tsheb thauj mus los, feem ntau hauv kev sib txhuam coefficient CRH2 EMUs, tsis tshua muaj kev sib txhuam TGV EMUs thiab kev sib txhuam qis TGV subway tsheb.
Lub CRH2 tsheb ciav hlau traction system tsim los ntawm Fabkis engineers yog ua los ntawm titanium alloy. Qhov no yog thawj zaug hauv ntiaj teb uas titanium alloy tau siv.

Nyob rau xyoo 1970, German thiab Italian railway departments siv titanium alloys nyob rau hauv rail transit tsheb braking systems, feem ntau nyob rau hauv lub tsheb ciav hlau braking pab kiag li lawm, xws li lub ntsiab brakes, nres discs thiab nres nres.
Thaum lub sij hawm lub tsheb ciav hlau braking txheej txheem, titanium alloy muaj peev xwm nqus tau ib tug loj npaum li cas ntawm tshav kub zog, yog li no zoo txo ​​cov kev sib txhuam coefficient ntawm lub log thiab ntsia; Nyob rau tib lub sijhawm, titanium alloy yuav tsis tsim sparks thaum lub sijhawm braking, tsis txhob muaj hluav taws kub nyhiab los ntawm kev sib txhuam.
Tom qab xyoo 1980, cov teb chaws thoob plaws ntiaj teb maj mam paub qhov zoo thiab muaj txiaj ntsig ntawm titanium alloys hauv tsheb thauj mus los, thiab pib siv lawv rau cov tsheb thauj mus los.
Fabkis, Lub teb chaws Yelemees, Ltalis, Nyiv thiab lwm lub tebchaws tau nquag kawm txog kev siv thev naus laus zis thiab kev vam meej ntawm titanium alloys hauv tsheb thauj mus los. Fabkis pib tshawb fawb txog kev siv cov titanium alloys hauv tsheb thauj mus los hauv 1980s lig.
Nyiv pib ua kev tshawb fawb txog kev siv thev naus laus zis ntawm titanium alloys hauv kev tsheb ciav hlau thauj mus los hauv nruab nrab -1980s. Lub Tsev Kawm Ntawv Qib Siab Tokyo, Hokkaido University, Waseda University, thiab lwm yam, thiab cov tuam txhab tsim tsheb ciav hlau tau sib koom ua ke tshawb fawb txog kev siv thev naus laus zis ntawm titanium alloys hauv tsheb thauj mus los.
Txij li thaum nruab nrab -1990s, lub teb chaws thoob ntiaj teb tau ua tiav ntau dua hauv kev tshawb fawb txog kev siv thev naus laus zis ntawm titanium alloys hauv tsheb thauj mus los. Tebchaws Asmeskas, United Kingdom, Australia, Canada thiab lwm lub tebchaws siv cov titanium alloys los tsim cov brakes thiab nres nres rau cov tsheb ciav hlau ceev.
Lub Tsev Kawm Ntawv Qib Siab Tokyo hauv Nyij Pooj tau ua tiav kev tshawb fawb ntau yam ntawm kev kub ceev tsheb ciav hlau nres disc cov ntaub ntawv thiab cov txheej txheem tsim khoom. Lub teb chaws Yelemees pib titanium alloying ntawm nres discs rau high-ceev tsheb ciav hlau nyob rau hauv thaum ntxov 1990s.
Txawm li cas los xij, daim ntawv thov ntawm titanium alloys nyob rau hauv domestic tsheb thauj mus los yog tseem nyob rau hauv nws cov me nyuam mos. Yog tias peb xav txhawb kev siv cov titanium alloys hauv cov tsheb thauj mus los ntawm kev loj, cov teeb meem hauv qab no yuav tsum tau daws:
Txhawm rau txhim kho daim ntawv thov kev ua tau zoo thiab zoo ntawm titanium alloys hauv tsheb thauj mus los, nws yog qhov tseem ceeb los daws cov teeb meem xws li cov kab nrib pleb, qhov pores thiab slag inclusions uas nquag tshwm sim hauv titanium alloys thaum lub sij hawm vuam, thiab tsim kev sib koom ua ke, tsim qauv thiab scientific titanium alloy vuam txheej txheem specifications thiab xeem txoj kev coj thiab txhim kho qhov zoo ntawm titanium alloy vuam.
Raws li cov yam ntxwv ntawm cov tsheb ciav hlau thauj mus los thiab cov kev xav tau ntawm kev pabcuam ib puag ncig, cov txheej txheem sib raug zoo raug tsim los coj kev siv cov titanium alloys hauv tsheb thauj mus los hauv kuv lub tebchaws. Tau kawg, kuv lub teb chaws tseem tab tom ntsib ntau yam teeb meem hauv kev siv cov titanium alloys hauv tsheb thauj mus los.
