Impumelelo kubuchwepheshe bokwelapha okungaphezulu ichaza kabusha ukusebenza kweamathuluzi e-carbide ayisicefe, ethembisa izinzuzo ezibalulekile ekusebenzeni kahle, ikhwalithi yokuqeda, nokuphila isikhathi eside kwamathuluzi kubakhiqizi abanembile emhlabeni wonke. Ngokusebenzisa inqubo ethuthukisiwe yokwamukela izinto ethuthukiswe eJalimane, isizukulwane sakamuva samathuluzi siletha indida eyingqayizivele: unqenqema oluguquliwe nge-microscopically olusika kakhulu, ngokushesha, futhi luhlanzeke kunangaphambili.
Emashumini eminyaka, ukuphishekela ubukhali bokugcina ekusetshenzisweni kwamathuluzi e-carbide kuvame ukuholela ekubeni sengozini okubalulekile: imiphetho entekenteke, insingo ezacile ejwayele ukucwiywa kancane kanye nokuguga okusheshayo, ikakhulukazi ngaphansi kokusebenza okuyisicefe okuphezulu ezintweni eziqinile njengezinsimbi eziqinile, ama-superalloy, nezinsimbi ezisansimbi. Lokhu kuba ntekenteke kubangele ukuqedwa okungaguquguquki, ukwanda kokumelana nokusika, ukwehluleka kwamathuluzi ngaphambi kwesikhathi, kanye nento ekhungathekisayo "yokusika izimila" - unqenqema olwakhiwe (BUE) lapho okubalulekile kwengcezu yokusebenza kushisela ethuluzini, okonakalisayo kanye nekhwalithi ephezulu.
Inqubo esanda kuthuthukiswa yokudlula ibhekana ngqo nale nselele. Ukudlulela ngale kokuzungezisa unqenqema noma uhlelo lokuhlanganisa oluvamile, lobu buchwepheshe bobunikazi baseJalimane bubandakanya ukwelashwa kwamakhemikhali nokwemishini okulawulwa kakhulu. Ilungisa kahle i-micro-geometry yonqenqema lokusika ezingeni le-sub-micron.
Isayensi Yokulawulwa "Ukudunga":
Indalo Ye-Minus-Bevel Eqondiwe: Esikhundleni sokushiya unqenqema olucijile ngokwe-athomu (noluphukayo), inqubo idala okungaguquguquki ngendlela emangalisayo, i-bevel eminuscule noma irediyasi eduze konqenqema lokusika. Le-micro-bevel yakhelwe ukuthi ibe nkulu ngokwanele ukuqeda amaphoyinti abuthakathaka, ajwayele ukuphuka.
Ukuqeda Ukukhubazeka Okuncane: Inqubo kanye kanye yenza bushelelezi futhi isuse ukungahambi kahle kwe-microscopic okungokwemvelo kanye nezindawo zokucindezeleka ezisele enqubweni yokugaya, idale indawo yoguquko engenasici ngemuva komkhawulo wangempela wokusika.
Ubuqotho Bomphetho Obuthuthukisiwe: Umphumela uba unqenqema olugcina ukucijile okukhethekile kokusika kodwa olunamandla akhuphukile kanye nokumelana nokuqhekeka nokubhakuzisa.
Izinzuzo Zokusebenza Emhlabeni Wangempela:
Lolu nqenqema oluklanywe ngobunyoninco luhumusha ezinzuzweni ezibambekayo endaweni yesitolo:
Ukusika "okubukhali futhi kuyashesha": Ngokuphambene nomuzwa, unqenqema oludlulisiwe luzwa ukumelana nokusika okuncane kakhulu. Ngokuvimbela i-micro-chipping kanye nokuqaliswa kwe-BUE, ithuluzi ligcina i-geometry yalo eklanyelwe kanye nobukhali isikhathi eside. Lokhu kuvumela isivinini esiphezulu somshini (Vc) namazinga okuphakelayo (f) ngaphandle kokudela ubuqotho bonqenqema, okuthuthukisa ukukhiqiza ngokuqondile.
I-Superior High Finish: Ukuqedwa kwe-micro-chipping kanye nonqenqema olwakhiwe kubalulekile ukuze kuzuzwe ukuqedwa okukhethekile. Isenzo sokusika esizinzile, esibushelelezi sikhiqiza ama-bores anamanani aphansi ka-Ra, ngokuvamile asusa imisebenzi yokuqedela yesibili. Ifa "lenqubo yokwenza imishini yaseJalimane" ligcizelela lokhu kuphokophela kokunemba okuphelele nokuphelela kwendawo.
I-Reduced Cutting Tumors (BUE): Ngokushelela unqenqema nokususa amaphuzu okucindezeleka, i-passivation inciphisa izingosi ze-nucleation lapho izinto zokusebenza zinganamathela khona. Kuhlanganiswe nesenzo sokusika esibushelelezi kanye nokungqubuzana okuncishisiwe, lokhu kunciphisa kakhulu ukwakheka konqenqema olwakhiwe, kuqinisekisa ukugeleza kwe-chip okungaguquki namandla okusika azinzile.
Impilo Yethuluzi Elinwetshiwe: Amandla onqenqema athuthukisiwe kanye nokumelana nokuqoshwa nokuguga kuhumusheka ngokuqondile ekuphileni kwamathuluzi asebenzisekayo isikhathi eside. Amathuluzi asebenza ngokungaguquki ezingxenyeni eziningi ngaphambi kokudinga ukushintshwa noma ukulungiswa kabusha, ukunciphisa isikhathi sokuphumula nezindleko zamathuluzi ingxenye ngayinye.
Ukwethenjelwa Kwenqubo Ekhulayo: Ukunciphisa ukumelana nokusika kanye nokucindezelwa kwe-BUE kuholela ezimweni zokubikezela, ezinzile. Lokhu kunciphisa ukudlidliza, kuthuthukisa ukunemba kobukhulu, futhi kunciphisa ubungozi bezingxenye ezilahliwe ngenxa yokwehluleka kwamathuluzi noma ikhwalithi yendawo ephansi.
Umthelela Wemboni Nokutholakala:
Ubuchwepheshe buyasiza kakhulu ekufuneni izicelo ezivamile ku-aerospace, i-automotive powertrain, ukukhiqizwa kwemishini yezokwelapha, kanye nemikhakha yamandla, lapho izimbobo ezijulile eziyisicefe, ezinembile ezintweni ezinzima ziyinjwayelo. Abakhiqizi abazabalaza nekhwalithi yokuqeda, ukungahambisani kwempilo yamathuluzi, noma izinkinga ezakhiwe ngamaphethelo bangalabo abazuzayo.
