Zipangizo Zofunikira Zaukadaulo Zopangira Mabuleki Ogwira Ntchito Kwambiri, Kukana Kuwonongeka, ndi Kupanga Molondola

Kufotokozera kwa Meta

Dziwani momwe black silicon carbide imathandizira mabuleki a ceramic a carbon kudzera mukuwongolera kapangidwe ka microstructure, kukhazikika kwa kukangana, kukana kutentha, komanso kukonza molondola. Chinthu chofunikira kwambiri paukadaulo wapamwamba wa mabuleki a magalimoto.

Chomera cha kaboniMakina oyendetsera mabuleki akhala njira yabwino kwambiri yogwiritsira ntchito magalimoto ogwira ntchito bwino, malo othamanga, magalimoto amagetsi apamwamba, ndi ntchito zoyendera ndege komwe kapangidwe kopepuka komanso kudalirika kwambiri kwa kutentha ndikofunikira. Poyerekeza ndi ma disc achikhalidwe a brake achitsulo chopangidwa ndi chitsulo, ma carbon ceramic composites amapereka zabwino zazikulu, kuphatikiza kulemera kochepa, kutentha kwambiri kogwira ntchito, moyo wautali wautumiki, komanso machitidwe okhazikika a braking pansi pa kupsinjika mobwerezabwereza. Komabe, maubwino awa sapezeka ndi ulusi wa kaboni wokha. Msana weniweni wa mabuleki a ceramic a carbon uli mukupanga gawo la ceramic la silicon carbide (SiC) lomwe limalimbitsa kapangidwe kake ndikukhazikitsa magwiridwe antchito a friction. Pakupanga kwamakono, black silicon carbide yatsimikiziridwa kukhala imodzi mwazinthu zothandiza kwambiri komanso zogwira mtima za SiC zothandizira njirayi. Chifukwa cha kuuma kwake kwakukulu, kukhazikika kwa kutentha, kusakhala bwino kwa mankhwala, komanso kugwiritsa ntchito bwino ndalama, black SiC imagwiritsidwa ntchito kwambiri kuyambira kukonzekera zinthu zopangira mpaka kukonza komaliza, zomwe zimapangitsa kuti ikhale yothandiza kwambiri paukadaulo wapamwamba wa brake wa carbon ceramic.

Pa nthawi yokonza zinthu,kabide wakuda wa silikoni Imagwira ntchito yofunika kwambiri powongolera njira yolumikizirana kapena njira yolowera ya silicon yamadzimadzi yomwe imagwiritsidwa ntchito popanga ma disc a brake a carbon ceramic. Pa gawoli, silicon yosungunuka imalowa mu preform ya carbon yokhala ndi porous ndipo imachitapo kanthu kuti ipange silicon carbide, ndikupanga C/SiC composite yolimba. Kufanana kwa izi kumakhudza mwachindunji mphamvu, kulimba, komanso kudalirika kwa nthawi yayitali. Tinthu ta Black SiC titha kugwira ntchito ngati mfundo za nucleation zomwe zimalimbikitsa mapangidwe a SiC nthawi zonse pomwe zimachepetsa kukula kosakhazikika, malo obisika mkati, kapena zolakwika za kapangidwe kake. Mwa kuthandiza kuwongolera kugawa kwa gawo ndikukonzanso kapangidwe ka microstructure, tinthu tating'onoting'ono timawongolera kuchulukana ndi umphumphu wa makina, kulola disc yomaliza ya brake kupirira katundu wolemera kwambiri komanso kutentha. Kapangidwe kolamulidwaka kamathandizanso mphamvu yokakamiza, mphamvu yosinthasintha, komanso kukana kutopa, kuonetsetsa kuti zigawo za brake zimasunga magwiridwe antchito okhazikika ngakhale pansi pa mikhalidwe yolimba, yobwerezabwereza monga yomwe imachitikira m'malo othamanga kapena oyendetsa mwachangu kwambiri.

Kuchokera pakuwona momwe zinthu zilili, gawo la silicon carbide lomwe limapangidwa mothandizidwa ndi black SiC limatsimikizira mwachindunji zinthu zambiri zofunika kwambiri pamakina oyendetsera mabuleki a ceramic a carbon. Kulimba kwapadera kwa silicon carbide kumapereka kukana kwakukulu kwa kuwonongeka, kuchepetsa kwambiri kutayika kwa zinthu pakati pa diski ndi brake pad. Nthawi yomweyo, kutentha kwake kwakukulu kumathandiza kuti kutentha kutayike mwachangu, kupewa kutentha kwambiri ndikuchepetsa chiopsezo cha kutha kwa mabuleki. Kuchuluka kwa kutentha kochepa kwa SiC kumathandiziranso kukana kutentha, kulola brake disc kupirira kusintha kwadzidzidzi kwa kutentha kuchokera kumadera ozungulira mpaka madigiri Celsius mazana angapo kapena kupitirira chikwi popanda kusweka kapena kusintha. Makhalidwe ophatikizidwawa amatsimikizira kuti brake coefficient yokhazikika, yankho losalala la braking, phokoso lochepa ndi kugwedezeka, komanso moyo wautali wautumiki poyerekeza ndi mabuleki achitsulo wamba. Zotsatira zake, black silicon carbide imathandizira osati kokha kulimbitsa kapangidwe kake komanso chitetezo chonse komanso kusinthasintha kwa magwiridwe antchito a braking.

Kupatula phindu lake pakupanga zinthu zophatikizika komanso magwiridwe antchito, black silicon carbide ndi yofunika kwambiri pakupanga ndi kumaliza zinthu za carbon ceramic. Akangoyatsidwa ndi kulumikizidwa, ma disc a C/SiC brake amakhala ovuta kwambiri komanso ovuta kuwagwiritsa ntchito pogwiritsa ntchito zida wamba. Ma abrasives achikhalidwe nthawi zambiri amawonongeka mwachangu kapena amagwira ntchito yochepa, zomwe zimapangitsa kuti pakhale ndalama zambiri zopangira komanso kuti pamwamba pake pakhale bwino.Black SiCKomabe, ma abrasives amapereka m'mbali zakuthwa zodulira, mphamvu yopukutira mwamphamvu, komanso kulimba bwino, zomwe zimapangitsa kuti zikhale zoyenera kupukutira molondola, kupanga mawonekedwe, kudula m'mphepete, komanso ntchito zomaliza pamwamba. Ma abrasives awa amalola opanga kuti akwaniritse kulekerera kolimba, kusalala kwa pamwamba, komanso kusalala kolondola, zonse zomwe ndizofunikira kwambiri pakuzungulira bwino komanso kuletsa mabuleki. Chifukwa cha kulinganiza bwino pakati pa magwiridwe antchito ndi mtengo, black silicon carbide yakhala imodzi mwazipangizo zodulira zomwe zimagwiritsidwa ntchito kwambiri popanga mabuleki a ceramic a carbon m'mafakitale akuluakulu komanso opanga zinthu zapamwamba kwambiri.

Carbide yakuda ya silicon imagwiritsidwanso ntchito kwambiri pakufufuza, kupanga, ndi kuyesa bwino zipangizo zamakono zoyendetsera mabuleki. Kukula kosiyanasiyana kwa grit ndi magiredi a ufa zimathandiza mainjiniya kutsanzira momwe zinthu zimagwirira ntchito, kuwunika kukhazikika kwa kukangana, ndikuphunzira momwe zinthu zadothi zimagwirira ntchito ndi mabuleki. M'malo ochitira kafukufuku, SiC yakuda imathandiza kuwunika kukana kukanda, kukonza mapangidwe ake, ndikukonzanso kapangidwe kake kuti kakhale kolimba komanso kutentha. Kusinthasintha kwake kumapangitsa kuti ikhale yoyenera kupanga zitsanzo, kuyesa pang'ono, komanso kukonza njira zopitilira. Izi zikutanthauza kuti carbide yakuda ya silicon siigwira ntchito yopangira yokha komanso yogwiritsidwa ntchito popanga zinthu zatsopano, kuthandiza ofufuza kupititsa patsogolo ukadaulo wa mabuleki a ceramic a carbon ndikupanga zipangizo zam'badwo wotsatira kuti zigwiritsidwe ntchito molimbika kwambiri.

Pamene makampani opanga magalimoto ndi magalimoto oyenda akupitilizabe kupita ku kapangidwe kopepuka, magwiridwe antchito apamwamba, komanso kudalirika kwakukulu, kugwiritsa ntchito makina oyendetsera mabuleki a kaboni akuyembekezeka kufalikira kupitirira magalimoto akuluakulu kupita ku magalimoto amagetsi, nsanja zodziyimira pawokha, masewera a njinga zamoto, ndi zida zamlengalenga. Kufunika kumeneku kukuwonjezeranso kufunika kwapamwamba kwambiri.kabide ya silikonizipangizo zomwe zingapereke magwiridwe antchito okhazikika pamene zikusunga kuthekera kwachuma. Ndi kuphatikiza kwake kwabwino kwa kuuma, kukhazikika kwa kutentha, magwiridwe antchito, komanso kutsika mtengo, black silicon carbide ikadali imodzi mwazosankha zothandiza kwambiri komanso zokulirapo kwa opanga padziko lonse lapansi. Kuyambira paukadaulo wazinthu ndi kulumikizana kwa reaction mpaka makina olondola komanso kuyesa magwiridwe antchito, black SiC imathandizira gawo lililonse la unyolo wopanga, zomwe zimapangitsa kuti ikhale yoposa yopepuka kapena yowonjezera. Kwenikweni, ndi chinthu choyambirira chaukadaulo chomwe chikupitilizabe kutsogolera kusintha kwa machitidwe otetezeka, opepuka, komanso olimba a carbon ceramic brake.
