Izinto Zobunjiniyela Ezibalulekile Zokubhuleka Okuphezulu, Ukumelana Nokuguguleka, kanye Nokukhiqiza Ngokucophelela

Incazelo ye-Meta

Thola ukuthi i-black silicon carbide ithuthukisa kanjani izinhlelo zamabhuleki ze-carbon ceramic ngokulawula isakhiwo esincane, ukuqina kokungqubuzana, ukumelana nokushisa, kanye nomshini wokulungisa ngokunemba. Izinto ezibalulekile zobuchwepheshe obuthuthukisiwe bokubhuleka kwezimoto.

I-carbon ceramicIzinhlelo zamabhuleki sezibe yisisombululo esithandwayo sezimoto ezisebenza kahle kakhulu, amapulatifomu okugijima, izimoto zikagesi zekhwalithi ephezulu, kanye nezinhlelo zokusebenza zezindiza lapho ukwakhiwa okulula kanye nokuthembeka okukhulu kokushisa kubalulekile. Uma kuqhathaniswa nama-disc amabhuleki ensimbi ajwayelekile, ama-composite e-carbon ceramic anikeza izinzuzo ezibalulekile, kufaka phakathi isisindo esiphansi, amazinga okushisa aphezulu okusebenza, impilo yesevisi ende, kanye nokuziphatha okuhlala njalo kokubhuleka ngaphansi kokucindezeleka okuphindaphindiwe. Nokho, lezi zinzuzo azitholakali nge-carbon fiber yodwa. Umgogodla wangempela wamabhuleki e-carbon ceramic usekwakheni isigaba se-ceramic se-silicon carbide (SiC) esiqinisa isakhiwo se-composite futhi siqinise ukusebenza kokungqubuzana. Embonini yesimanje, i-black silicon carbide ibonakale ingenye yezinto ze-SiC ezisebenzayo nezisebenza kahle kakhulu zokusekela le nqubo. Ngenxa yobunzima bayo obuphezulu, ukuzinza kokushisa, ukungangeni kwamakhemikhali, kanye nokusebenza kahle kwezindleko, i-black SiC isetshenziswa kabanzi kusukela ekulungiseleleni izinto zokusetshenziswa kuya ekusetshenzisweni kokugcina, okwenza kube yinto ebalulekile enika amandla ubuchwepheshe obuthuthukisiwe be-carbon ceramic brake.

Ngesikhathi sesigaba sokucubungula izinto,i-carbon carbide emnyama idlala indima ebalulekile ekulawuleni inqubo yokubopha ukusabela noma inqubo yokungena kwe-silicon ewuketshezi esetshenziselwa ukukhiqiza ama-disc e-brake ceramic e-carbon. Kulesi sigaba, i-silicon encibilikisiwe ingena kwi-preform yekhabhoni enezimbobo bese isabela ekwakheni i-silicon carbide, idale i-composite ye-C/SiC exinene. Ukufana kwalokhu kusabela kuthinta ngqo amandla, ukuqina, kanye nokuthembeka kwesikhathi eside. Izinhlayiya ze-Black SiC zingasebenza njengezindawo ze-nucleation ezikhuthaza ukwakheka kwe-SiC okuqhubekayo ngenkathi kunciphisa ukukhula okungajwayelekile, izikhala zangaphakathi, noma amaphutha esakhiwo. Ngokusiza ekulawuleni ukusatshalaliswa kwesigaba kanye nokulungisa isakhiwo esincane, lezi zinhlayiya zithuthukisa ubuningi kanye nobuqotho bomshini, okuvumela i-disc yokugcina ye-brake ukuthi imelane nemithwalo enzima kanye nokujikeleza kokushisa. Lokhu kwakheka okulawulwayo kuthuthukisa namandla okucindezela, amandla okuguquguquka, kanye nokumelana nokukhathala, okuqinisekisa ukuthi izingxenye ze-brake zigcina ukusebenza okuzinzile ngisho nangaphansi kwezimo zokubopha ezinolaka, eziphindaphindwayo njengalezo ezitholakala ezindaweni zokugijima noma zokushayela ngesivinini esikhulu.

Ngokombono wokusebenza, isigaba se-silicon carbide esakhiwe ngosizo lwe-black SiC sinquma ngqo izici eziningi ezibalulekile zokusebenza kwezinhlelo zamabhuleki ze-carbon ceramic. Ubulukhuni obumangalisayo be-silicon carbide buhlinzeka ngokumelana nokuguguleka okuvelele, kunciphisa kakhulu ukulahleka kwezinto ezibonakalayo esibonakalayo sokungqubuzana phakathi kwediski nephedi yamabhuleki. Ngesikhathi esifanayo, ukuhanjiswa kwayo okuphezulu kokushisa kwenza ukushabalaliswa kokushisa okusheshayo, kuvimbele ukushisa ngokweqile futhi kunciphise ingozi yokushabalala kwamabhuleki. I-coefficient yokwanda kokushisa okuphansi ye-SiC iphinde ithuthukise ukumelana nokushaqeka kokushisa, okuvumela idiski yamabhuleki ukuthi ibekezelele izinguquko zokushisa ezisheshayo kusuka ezimweni ezizungezile kuya kumakhulu amaningana noma ngisho nangaphezu kwenkulungwane yama-degree Celsius ngaphandle kokuqhekeka noma ukuguquka. Lezi zici ezihlanganisiwe ziqinisekisa i-coefficient yokungqubuzana ezinzile, impendulo ebushelelezi yokubhuleka, umsindo ophansi nokudlidliza, kanye nokuphila isikhathi eside kakhulu uma kuqhathaniswa namabhuleki ensimbi avamile. Ngenxa yalokho, i-black silicon carbide ayinikezi nje kuphela ekuqinisweni kwesakhiwo kodwa futhi nasekuphepheni okuphelele kanye nokuvumelana kokusebenza kokubhuleka.

Ngaphandle kokufaka isandla ekwakhekeni kwenhlanganisela kanye nokusebenza kahle, i-black silicon carbide ibaluleke ngokulinganayo ezigabeni zokugaya nokuqeda izingxenye ze-carbon ceramic. Uma sezifakwe futhi zahlanganiswa, ama-brake disc e-C/SiC aba nzima kakhulu futhi kunzima ukuwacubungula kusetshenziswa amathuluzi ajwayelekile. Ama-abrasives endabuko avame ukubonisa ukuguguleka okusheshayo noma ukusebenza kahle okuphansi, okuholela ezindleleni zokukhiqiza eziphezulu kanye nekhwalithi ephansi.I-Black SiCNokho, ama-abrasives anikeza imiphetho yokusika ebukhali, ikhono lokugaya eliqinile, kanye nokuqina okuhle kakhulu, okwenza kube kuhle kakhulu ekugayeni ngokunembile, ekwakheni, ekunqumeni imiphetho, kanye nasekuqedeni ubuso. Lawa ma-abrasives avumela abakhiqizi ukuthi bafinyelele ukubekezelelana okuqinile, ukuba lukhuni kwendawo okubushelelezi, kanye nokuba bushelelezi okunembile, konke okubalulekile ekujikelezeni okulinganiselayo kanye nokubhuleka okuphephile. Ngenxa yokulinganisela kwayo okuhle phakathi kokusebenza kanye nezindleko, i-black silicon carbide isibe ngenye yezinto ezisetshenziswa kakhulu zokubhula ekushiseni amabhuleki e-carbon ceramic kokubili ekukhiqizweni okukhulu kwezimboni kanye nasekukhiqizeni okukhethekile okuphezulu.

I-black silicon carbide nayo isetshenziswa kabanzi ocwaningweni, ekuthuthukisweni, nasekuhlolweni kwekhwalithi kwezinto zokubhuleka ezithuthukisiwe. Ubukhulu obuhlukene begrit kanye namazinga empuphu kuvumela onjiniyela ukulingisa izimo zokuguguleka zangempela, bahlole ukuqina kokungqubuzana, futhi bafunde ukusebenzisana phakathi kwezindawo ze-ceramic nama-brake pad. Ezindaweni zelebhu, i-black SiC isiza ekuhloleni ukumelana nokuguguleka, ilungise ukwakheka, futhi icwenge izakhiwo ezihlanganisiwe ukuze ifinyelele ukuqina okungcono kanye nokuziphatha kokushisa. Ukuguquguquka kwayo kuyenza ifaneleke ekuthuthukisweni kwe-prototype, ukuhlolwa kweqembu elincane, kanye nokuthuthukiswa kwenqubo okuqhubekayo. Lokhu kusho ukuthi i-black silicon carbide ayisebenzi nje kuphela njengomkhiqizo ongasetshenziswa kodwa futhi njengethuluzi eliyisu lokusungula izinto ezintsha, isiza abacwaningi ukuthi bacindezele imingcele yobuchwepheshe be-carbon ceramic brake futhi bathuthukise izinto zesizukulwane esilandelayo zezinhlelo zokusebenza ezidinga kakhulu.

Njengoba izimboni zezimoto nezokuhamba ziqhubeka nokuya ekwakhiweni okulula, ukusebenza kahle okuphezulu, kanye nokuthembeka okuthuthukisiwe, ukwamukelwa kwezinhlelo zamabhuleki e-carbon ceramic kulindeleke ukuthi kwande ngale kwezimoto ezinkulu kuya ezimotweni zikagesi, amapulatifomu azimele, imidlalo yezimoto, kanye nemishini yezindiza. Lesi sidingo esikhulayo sigcizelela ukubaluleka kwekhwalithi ephezulu.i-silicon carbideizinto ezingaletha ukusebenza okulinganayo ngenkathi zigcina ukwenzeka kwezomnotho. Ngenhlanganisela yayo enhle kakhulu yokuqina, ukuzinza kokushisa, ukusebenza kahle kokucubungula, kanye nokungabizi, i-black silicon carbide ihlala ingenye yezinketho ezisebenzayo kakhulu nezikhuliswayo zabakhiqizi emhlabeni jikelele. Kusukela kubunjiniyela bezinto ezibonakalayo kanye nokubopha kokusabela kuya ekusetshenzisweni okunembile kanye nokuhlolwa kokusebenza, i-black SiC isekela zonke izinyathelo zochungechunge lokukhiqiza, okwenza kube ngaphezu kokukhuhla okulula noma okungeziwe. Empeleni, iyinto yobunjiniyela eyisisekelo eqhubeka nokuqhuba ukuvela kwezinhlelo zamabhuleki e-carbon ceramic eziphephile, ezilula, nezihlala isikhathi eside.
