Ukungqubuzana nokuguga kudlangile ezinhlelweni zemishini, okuhlanganisa izinjini, ngenxa yokusebenzisana phakathi kwezingxenye zemishini I-Friction idla amandla amaningi, futhi ukuguga kuzoholela ekuhlulekeni ngaphambi kwesikhathi kwezingxenye. Ukuze kuthuthukiswe ukusebenza kahle kwesevisi nempilo yenjini, ukungqubuzana nokuguga phakathi kwezingxenye kufanele kuncishiswe. Ubuchwepheshe bokuthambisa buwubuchwepheshe obubalulekile bokuxazulula ukungqubuzana nokuguga, ukwelula impilo yesevisi yenjini kanye nokunciphisa ukusetshenziswa kwamandla.
Ukusetshenziswa kwe-graphene, i-nanomaterial eyingqayizivele, kuthuthukisa kakhulu izici zokugcoba zamafutha e-base engine, ngaleyo ndlela kuthuthukisa ukusebenza kwe-tribological.Lapho injini iqaliswa, izinhlayiya ze-graphene nano zivumela ukungena nokumboza imifantu egugile (i-surface asperities) yakhe ifilimu elincane elivikelayo phakathi kwensimbi. izingxenye zamaphistoni anyakazayo nama-cyliner.Ngenxa yezinhlayiya zamangqamuzana amancane kakhulu e-graphene, ingakwazi ukukhiqiza umphumela webhola phakathi nokungqubuzana phakathi kwesilinda nepiston, iguqule ukuslayida okuslayidayo phakathi kwezingxenye zensimbi kube ukungqubuzana okugoqayo phakathi kwezingqimba zegraphene. Ngokunciphisa kakhulu ukungqubuzana nokuguga, kuhlanganiswe nezakhiwo zempushana ezithuthukisiwe, amandla angonga futhi ukusetshenziswa kukaphethiloli kuphumelela kakhulu. Ngaphandle kwalokho, ngesikhathi sengcindezi ephezulu kanye nezinga lokushisa, i-graphene izonamathisela endaweni yensimbi futhi ilungise ukuguga kwenjini (ubuchwepheshe be-carburizing), okuzokwandisa impilo yesevisi yenjini. Uma injini isebenza kahle, ukukhishwa kwekhabhoni nobuthi endaweni ezungezile kuyehla futhi imisindo/ukundindizela kuzokwehla ngenxa yalokho.
I-Graphene iyinto eguquguqukayo ehlanganisa ungqimba olulodwa lwama-athomu ekhabhoni ahlelwe ngehele lekhekheba lezinyosi elinezinhlangothi ezimbili. Yatholwa ngo-2004, yazuza u-Andre Geim no-Konstantin Novoselov uMklomelo kaNobel we-Physics ka-2010. I-Graphene ikhombisa izakhiwo ezingajwayelekile eziyenza ithandeke ngokwedlulele ezinhlelweni ezihlukene. Iqine kakhulu, kodwa ilula, inamandla aqinile aphindwe izikhathi eziyi-100 kunensimbi. Iphinde ibe nokuhamba kahle kukagesi, okuvumela ama-electron ukuthi ageleze kuwo ngesivinini esiphezulu kakhulu. Ngaphezu kwalokho, ine-conductivity ye-thermal ehlaba umxhwele, eyivumela ukuthi ikhiphe ukushisa ngokuphumelelayo. Lezi zakhiwo ezimangalisayo ziletha i-graphene ezinhlelweni eziningi ezingasetshenziswa ezimbonini ezahlukahlukene. Kwezogesi, ithembisa ukushayela intuthuko kuma-transistors asheshayo, asebenza kahle, izibonisi eziguqukayo namabhethri asebenza kahle kakhulu. Emkhakheni wamandla, izinto ezisekelwe ku-graphene ziyahlolwa ukuze kutholwe amaseli elanga asebenza kahle kakhulu, amaseli kaphethiloli kanye nemishini yokugcina amandla. Amandla ayo kanye nokuguquguquka kwayo kuyenza ilungele ukusetshenziswa kwesayensi yezinto ezifana nezinhlanganisela, okokuhlanganisa nezindwangu. Naphezu kwamandla ayo amakhulu, ukukhiqizwa okukhulu kwe-graphene kanye nokuhlanganiswa kwayo emikhiqizweni yezohwebo kuseyinselele. Kodwa-ke, ucwaningo oluqhubekayo nentuthuko iyaqhubeka nokuqhuba ukusetshenziswa okungokoqobo kwezakhiwo ezimangalisayo ze-graphene.
Ngemva kokwengeza imikhiqizo yethu, ukuhlola kubonisa ukuthi ukungqubuzana kunciphe kakhulu futhi ukusebenza kahle kokugcoba kuthuthukiswa kakhulu.
