I-carbide enosimende iyingxubevange eyenziwe ngezinhlanganisela eziqinile zezinsimbi eziphikisayo nezinsimbi ezibophayo ngenqubo ye-powder metallurgy.Ngokuvamile kwenziwa ngezinto ezibophayo ezithambile (njenge-cobalt, i-nickel, insimbi noma ingxube yezinto ezingenhla) kanye nezinto eziqinile (njenge-tungsten carbide, molybdenum carbide, tantalum carbide, chromium carbide, vanadium carbide, titanium carbide noma izingxube).
I-carbide enosimende inochungechunge lwezakhiwo ezinhle kakhulu, njengokuqina okuphezulu, ukumelana nokugqoka, amandla amahle nokuqina, ukumelana nokushisa, ukumelana nokugqwala, njll., ikakhulukazi ubulukhuni bayo obuphezulu nokumelana nokugqoka, okuhlala kungashintshile ngisho naku-500 ℃ futhi kusenayo. ubulukhuni obuphezulu ku-1000 ℃.Ezintweni zethu ezivamile, ubulukhuni busuka phezulu kuye phansi: idayimane elidayimane, i-cubic boron nitride, i-cermet, i-carbide enosimende, insimbi enesivinini esikhulu, futhi ukuqina kusuka phansi kuya phezulu.
I-carbide enosimende isetshenziswa kabanzi njengamathuluzi okusika, njengamathuluzi okujika, abasiki bokugaya, amapulani, izinsimbi zokubhoboza, izisiki eziyisicefe, njll., ukusika insimbi ensimbi, izinsimbi ezingezona ayoni, amapulasitiki, imicu yamakhemikhali, igraphite, ingilazi, itshe kanye insimbi evamile, kanye nokusika insimbi engangeni ekushiseni, insimbi engagqwali, insimbi ephezulu ye-manganese, insimbi yamathuluzi nezinye izinto okunzima ukuzenza ngomshini.
I-carbide enosimende inokuqina okuphezulu, amandla, ukumelana nokugqoka kanye nokumelana nokugqwala, futhi yaziwa ngokuthi "amazinyo ezimboni".Isetshenziselwa ukwenza amathuluzi okusika, amathuluzi okusika, amathuluzi e-cobalt nezingxenye ezingagugi.Isetshenziswa kabanzi embonini yezempi, i-aerospace, machining, i-metallurgy, ukumba uwoyela, amathuluzi ezimayini, ukuxhumana ngogesi, ukwakhiwa kanye neminye imikhakha.Ngokuthuthuka kwezimboni ezansi nomfula, isidingo semakethe ye-carbide enosimende siyakhula.Futhi esikhathini esizayo, ukukhiqizwa kwezikhali nemishini yobuchwepheshe obuphezulu, inqubekelaphambili yesayensi nobuchwepheshe obusezingeni eliphezulu kanye nokuthuthukiswa okusheshayo kwamandla enuzi kuzokwandisa kakhulu isidingo semikhiqizo ye-carbide enosimende enokuqukethwe kobuchwepheshe obuphezulu nokuzinza kwekhwalithi ephezulu. .
Ngo-1923, u-schlerter waseJalimane wengeza u-10% - 20% we-cobalt ku-tungsten carbide powder njenge-binder, futhi wasungula i-alloy entsha ye-tungsten carbide ne-cobalt.Ukuqina kwayo kungokwesibili ngemva kwedayimane, okuyi-carbide yokuqala eyenziwe usimende emhlabeni.Lapho usika insimbi ngethuluzi elenziwe ngele-alloy, i-blade izogqoka ngokushesha, futhi ngisho ne-blade izoqhekeka.Ngo-1929, u-schwarzkov wase-United States wengeza inani elithile le-carbides ehlanganisiwe ye-tungsten carbide ne-titanium carbide ekubunjweni kokuqala, okwathuthukisa ukusebenza kwamathuluzi okusika insimbi.Lena enye impumelelo emlandweni wokuthuthukiswa kwe-carbide esimende.
I-carbide enosimende ingaphinda isetshenziselwe ukwenza amathuluzi okumba amatshe, amathuluzi okumba, amathuluzi okumba, amathuluzi okulinganisa, izingxenye ezingagugi, ama-abrasives ensimbi, ama-cylinder liners, ama-precision bearings, imibhobho, isikhunta sehardware (njengesikhunta sezintambo zokudweba, isikhunta sebhawodi, nati. isikhunta, kanye nezibunjwa ezihlukahlukene zokubopha.Ukusebenza okuhle kakhulu kwe-carbide enosimende kancane kancane kuthathe indawo yokubumba insimbi yangaphambilini).
Emashumini amabili eminyaka adlule, i-carbide enosimende eboshiwe nayo iye yavela.Ngo-1969, iSweden yathuthukisa ngempumelelo ithuluzi elihlanganiswe ne-titanium carbide.I-substrate yethuluzi i-tungsten titanium cobalt cemented carbide noma i-tungsten cobalt cemented carbide.Ubukhulu be-titanium carbide coating ebusweni bungama-microns ambalwa kuphela, kodwa uma kuqhathaniswa namathuluzi e-alloy yomkhiqizo ofanayo, impilo yesevisi inwetshwa izikhathi ezingu-3, futhi ijubane lokusika lenyuka ngo-25% - 50%.Isizukulwane sesine samathuluzi okugcoba savela ngawo-1970, angasetshenziswa ukusika izinto okunzima ukuzisebenzisa ngomshini.
