Txhua tus neeg tsav tsheb tsawg kawg ib zaug tau hnov txog qhov muaj ntawm magnesium alloy log. Lawv paub, tab sis tsis ntau npaum li tib cov hlau lossis txhuas. Lub caij no, magnesium discs tuaj yeem khav theeb tag nrho cov txiaj ntsig zoo uas tsis tuaj yeem txhim kho kev ua haujlwm zoo ntawm ob lub discs thiab lub tsheb. Cia peb saib txhua qhov zoo thiab qhov tsis zoo ntawm cov khoom los ntawm cov alloys.

Ntawm cov log tsheb

Lub ntsiab ntxiv ntawm cov khoom siv lub teeb-alloy, txawm tias nws yog ua los ntawm aluminium alloy lossis nrog ntxiv ntawm magnesium, yog ib qho loj uas tsawg dua qhov hnyav ntawm lub stamped disc. Tsis tas li ntawd cam khwb cia lub log yog ntau ruaj, siab dua tiv thaiv corrosion. Thiab qhov tseem ceeb tshaj plaws yog tias lub log alloy muaj qhov zoo nkauj dua.

Nrog qhov hnyav, txhua yam yog qhov tseeb - qhov hnyav qis dua vim yog siv cov alloys sib dua. Lub zog thiab kev tiv thaiv corrosion kuj yog qhov tshwm sim ntawm cov khoom siv thiab kev siv tshuab ntau lawm. Yog li ntawd,lub log alloy muaj peev xwm tiv taus qhov hnyav hnyav yam tsis muaj kev puas tsuaj loj. Yog tias qhov chaw puas lawm, yuav tsis muaj xeb. Raws li rau cov tsos, txhua yam nyob ntawm lub matrix - koj tuaj yeem tsim ntau txhiab tus qauv sib txawv. Los ntawm kev pleev xim rau hauv cov xim sib txawv, koj tuaj yeem ua tiav qhov zoo nkauj heev.

Lub log alloy kuj muaj ob peb qhov tsis zoo. Nrog lub zog siab, cov khoom muaj tsawg ductility thiab brittleness. Tsis tas li ntawd, nyob rau hauv cov kev tshwm sim ntawm cov kab nrib pleb, kev kho ntawm cov khoom yog laborious thiab tus nqi ntawm kev ua hauj lwm yog heev heev. Ib qho khoom ua los ntawm lub teeb alloys tuaj yeem tiv taus qhov cuam tshuam loj, tab sis yog tias qhov cuam tshuam quab yuam ntau dua li lub peev xwm ntawm disk, ces nws yuav tsis tsuas deform, tab sis yuav tawg los yog tawg. Lub zog kuj tsis yog ib qho ntxiv, tab sis yog qhov rho tawm. Thaum lub log tsoo, lub zog yuav raug xa mus rau lub tsheb ncua kev kawm tiav.

Qhov zoo ntawm cov khoom lag luam magnesium

Hu rau magnesium discs txoj kev daws teeb meem tsis tsim nyog - cov ntaub ntawv no tau siv ntev heev thiab muaj kev vam meej hauv ntau qhov chaw ntawm kev lag luam niaj hnub no. Kev lag luam automotive tsis muaj qhov zam. Yog tias peb tham txog cov khoom tshwj xeeb, ces cov log magnesium tau tswj kom cua tau kaum tawm txhiab mais txij li thawj qhov tshwm sim ntawm kev ua lag luam. Tab sis nws kuj tsis tuaj yeem hais tias magnesium alloys sai sai yuav hloov cov tsoos hlau forgings thiab cov khoom siv txhuas.

ML5 alloy yog siv los tsim cov discs. Qhov no yog cam khwb cia magnesium alloy. Nws tau dav siv rau kev tsim cov compressor vaj tse, crankcases, twj tso kua mis, nres tsevsystems thiab lwm yam ntsiab lus. Raws li cov yam ntxwv kev, ML5 yog ze tshaj rau AL2, AL4, AL9 silumin alloys. Lub ntsiab kom zoo dua ntawm ML5 yog qhov ceev txo los ntawm 33% piv rau AL4. Cov khoom qub nrog tib qhov ntom ntom yuav yog ib feem peb sib dua li ib feem ua los ntawm silumin.

Nrog rau ntau qhov zoo, magnesium alloy log kuj muaj ntau qhov tsis zoo, yog li kev xaiv ntawm ib lossis lwm qhov kev xaiv yog cov ntsiab lus. Yog tias tus tswv lub tsheb tsis tau ntsib cov khoom zoo li no, ces nws yuav tsum paub txog qhov tsis zoo thiab qhov zoo.

Lub yuag

Raws li nyob rau hauv cov ntaub ntawv ntawm cam khwb cia txhuas lub log, lub ntsiab kom zoo dua ntawm aluminium-magnesium alloy yog nws qhov hnyav hnyav, nrog rau tag nrho lwm yam zoo cuam tshuam nrog qhov no. Lub teeb ci ntawm lub disc tso cai rau lub tsheb tsav tau zoo dua, thiab caij nws tus kheej yuav yooj yim dua. Cov log hlau muaj qhov loj 4 npaug ntau dua li lub log magnesium. Titanium cov khoom hnyav 2.5 npaug hnyav dua. Txawm tias aluminium poob magnesium hauv qhov hnyav. Cov khoom muaj qhov hnyav ib thiab ib nrab zaug tsawg dua qhov hnyav ntawm txhuas.

Tsim

Vim qhov tseeb tias magnesium muaj cov qauv tshwj xeeb, cov tuam ntxhab tuaj yeem sim nrog cov duab ntawm cov disc raws li lawv nyiam. Koj tuaj yeem tau txais tus qauv tsim tshwj xeeb uas tsis tuaj yeem ua tiav siv lwm cov ntaub ntawv, thiab yog tias koj ua, ces koj yuav tsum poob rau hauv cov yam ntxwv ntawm kev ua haujlwm lossis lub zog ntawm cov qauv. Polished magnesium log saib tshwj xeeb tshaj yog impressive. Cov hlau muaj golden impurities uas zoo li flawless.

Tsis muajhlau nkees

Tsis zoo li txhuas lossis hlau, magnesium alloys tsis raug rau qaug zog. Yog hais tias lub disk raug rau nruab nrab thiab qis loads, cov hlau muaj peev xwm khaws nws cov yam ntxwv ntawm lub sij hawm ntev heev.

YElasticity

Cov khoom siv yog elastic heev thiab qhov no tso cai rau nws khaws cov duab los ntawm cov chaw tsim khoom. Vim qhov elasticity no, lub disk yog yooj yim dua tawg dua li khoov. Qhov no qhia tau hais tias cov pas dej thiab cov pob me me ntawm cov curbs yuav tsis txaus ntshai rau lub log.

Thermal conductivity

Nws siab heev no. Nws muab dab tsi? Magnesium rims muaj peev xwm nqus tau qhov kub ntawm lub nres disc thiab hub. Koj tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm qhov chaw nres tsheb, nrog rau kev txhim kho cov txheej txheem braking zoo.

Cons

Cov discs muaj ntau qhov zoo. Thiab yog tias txhua yam zoo heev, vim li cas magnesium rims muag tsis zoo? Tag nrho cov no yog vim muaj qhov tsis txaus.

tsis zoo corrosion

Nws tau hais saum toj no tias cov tsis-ferrous aluminium alloy cam khwb cia log muaj kev tiv thaiv corrosion siab, tab sis qhov no tsis yog hais txog magnesium. Txawm tias tom qab lub caij ntuj sov, lub ntug muaj peev xwm poob saum npoo kev ncaj ncees thiab lub zog. Nyob rau lub caij ntuj no, kev sim tiag tiag pib rau lub log magnesium - cov no yog qhov hloov pauv tsis tu ncua, cov av noo siab, ntsev thiab cov tshuaj reagents. Tag nrho cov no ua ke thiab sib cais tuaj yeem yooj yim rhuav tshem cov hlau. Tib txoj kev tawm yog siv cov txheej txheem tshwj xeeb rau lub disc. Tab sis qhov uas ploj lawm yog qhov tshwj xeeb saib uas tsuas yog alloy magnesium log muaj.

Ntseeg ntawm magnesium

Lwm qhov tsis zoo yog qhov hlau thiab magnesium alloys yooj yim heev rau nkag mus rau hauv cov tshuaj tiv thaiv tshuaj, thaum qhov tshwm sim yog kev puas tsuaj ntawm magnesium. Mounting xws li ib tug disc yuav tsum tau ib tug tshwj xeeb mus kom ze thiab feem ntau cov nqi ntxiv rau cov khoom.

YElasticity

Saum toj no hauv cov npe ntawm cov txiaj ntsig, elasticity tau hais. Lub disk tuaj yeem tawg sai sai, sib cais. dua khoov. Ntawm txoj kev hauv tsev, muaj ntau txoj hauv kev kom tau lub log rau hauv qhov tob. Cov no yog cam khwb cia txhuas log, tab sis nws yuav tsum tau qhia meej tias qhov no muaj tseeb dua rau cov khoom siv magnesium - cov qauv hlau ntawm no muaj cov nplej loj thiab brittleness.

Forged magnesium disc yog tsim los ntawm kub stamping tshuab. Nyob rau hauv cov nqe lus ntawm lub zog, nws yog xyaum nyob rau hauv tsis muaj txoj kev inferior rau txhuas los yog titanium. Lub zog yog txawm tias siab dua titanium, thaum tuav ductility thiab muaj zog tiv thaiv corrosion. Tab sis cov khoom no kim dua li cov cam khwb cia.

Tus nqi siab

Yav dhau los, magnesium alloys tsuas yog muaj rau kev lag luam aviation thiab chaw. Txawm li cas los xij, tom qab ntawd cov khoom siv tau pheej yig dua thiab pib siv hauv kev lag luam tsheb. Tab sis txawm coj mus rau hauv tus account qhov no txo nqi, tus nqi ntawm cov disks yog kim heev. Qhov no muaj tseeb rau cov khoom lag luam forged txawv teb chaws ua los ntawm cov khoom lag luam npaj tau zoo.

Magnesium hauv USSR

Magnesium log tau txawm nyob hauv USSR. Lawv tau tsim los ntawm kev tiv thaiv kev lag luam thiab ua haujlwm los ntawm cov neeg tsav tsheb sib tw hauv Soviet. Cov ntaub ntawv hais txogmuaj ob peb lub log no tab sis tseem muaj.

Nyob rau hauv nruab nrab-1980s, KULZ cog hauv Kamensk-Uralsk pib tsim VAZ KA-85 Vesna magnesium discs. Lawv tau npaj rau AvtoVAZ 01-05 classic kab. Los ntawm 85 mus rau 87, lub tuam txhab tsim 400 teeb. Nyob rau hauv 1987, cov qauv ntau yam ntawm cov nroj tsuag tau ntxiv nrog ib kab ntawm disks rau VAZ-08 "Secret". Xyoo 1989, KA-89 "Comfort" discs pib tsim. Qhov hnyav ntawm txhua lub log tsis ntau tshaj tsib kilograms. Tam sim no cov khoom zoo li no tsuas pom muaj nyob hauv kev lag luam thib ob xwb.

Zoo kawg

Yog li peb tau saib ntawm magnesium alloy log. Cov yam ntxwv zoo li cas lawv muaj kuj yog qhov tseeb. Niaj hnub no, SMZ magnesium discs tuaj yeem pom ntawm muag. Qhov no yog ib qho kev lag luam hauv tsev hauv Solikamsk. Txawm hais tias qhov kev thov tsis muaj zog rau cov khoom no, cov nroj tsuag tau tsim ntau yam qauv ntawm rims, uas niaj hnub no tuaj yeem pom ntawm tus nqi tsim nyog ntawm Avito thiab cov chaw zoo sib xws.
