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 zazo).
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 kusenobunzima 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 njengento yokusika ithuluzi, njengamathuluzi okuguqula, ama-milling cutters, amapulani, ama-drill bits, ama-cutters ayisicefe, njll., ukusika insimbi, izinsimbi ezingezona ayoni, amapulasitiki, imicu yamakhemikhali, i-graphite, ingilazi, itshe nensimbi evamile, kanye nokusika insimbi engashisi, insimbi engagqwali, insimbi ephezulu ye-manganese enzima umshini womshini, insimbi.
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 ingabuye isetshenziselwe ukwenza amathuluzi okumba amatshe, amathuluzi okumba, amathuluzi okumba, amathuluzi okulinganisa, izingxenye ezingagugi, ama-abrasives ensimbi, ama-cylinder liners, ama-precision bearings, imibhobho, isikhunta se-hardware (njengesikhunta sokudweba ucingo, isikhunta sebhawodi, isikhunta samantongomane, kanye nokusebenza okuhle kakhulu kwe-fastener yensimbi yangaphambilini. isikhunta).
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.
