I-carbide enesamente ibhekiselele kwimathiriyeli yealloyi eyenziwe ngekhompawundi yentsimbi ephikisayo njengematrix kunye nentsimbi yotshintsho njengesigaba sokubopha, emva koko yenziwe ngomgubo wesinyithi. Isetyenziswa kakhulu kwimoto, kwezonyango, emkhosini, kukhuselo lwesizwe, i-aerospace, inqwelomoya kunye namanye amacandelo. . Kuyafaneleka ukuba uqaphele ukuba ngenxa yeentlobo ezahlukeneyo kunye neziqulatho ze-carbides zetsimbi kunye nezibophelelo, iipropati ezibonakalayo kunye neekhemikhali ze-carbide ezilungiselelwe i-cemented nazo zihluke, kwaye iimpawu zabo zoomatshini kunye nezomzimba zixhomekeke kakhulu kuhlobo lwe-carbide yensimbi. Ngokwamacandelo aphambili ahlukeneyo, i-carbide ene-cemented inokwahlulwa ibe yi-YT uhlobo kunye ne-YG uhlobo lwe-cemented carbide.
Ukusuka kwinkcazo yembono, i-YT-type cemented carbide ibhekisela kwi-tungsten-titanium-cobalt-type cemented carbide, amacandelo aphambili yi-tungsten carbide, i-titanium carbide kunye ne-cobalt, kunye negama le-brand "YT" ("nzima, titanium" amagama amabini Chinese Pinyin prefix) Iqulunqwe ngumyinge womxholo we-titanium carbide, efana ne-YT15, okuthetha ukuba umxholo ophakathi we-titanium carbide yi-15%, kwaye enye i-carbide enesamente ene-tungsten carbide kunye nomxholo we-cobalt. I-YG-uhlobo lwe-cemented carbide ibhekisa kwi-tungsten-cobalt-uhlobo lwe-cemented carbide. Amacandelo aphambili yi-tungsten carbide kunye ne-cobalt. Umzekelo, i-YG6 ibhekisa kwi-tungsten-cobalt carbide enomndilili we-cobalt we-6% kwaye enye i-tungsten carbide.
Ngokwembono yokusebenza, zombini i-YT kunye ne-YG ye-cemented carbides inokusebenza kakuhle kokusila, amandla okugoba kunye nokuqina. Kufuneka kuqatshelwe ukuba ukuxhatshazwa kokugqoka kunye ne-thermal conductivity ye-YT-type cemented carbide kunye ne-YG-type cemented carbide zichasene. Owokuqala unokumelana nokunxiba okungcono kunye nokungahambi kakuhle kwe-thermal, ngelixa lo mva unokumelana nokunxiba kakubi kunye ne-thermal conductivity. Kulungile. Ukusuka kwimbono yesicelo, uhlobo lwe-YT olune-cemented carbide lufanelekile ukujika, ukucwangciswa ngokukrakra, ukugqiba isiqingatha, ukugaya ngokukrakra kunye nokubhobhoza kwendawo engapheliyo xa icandelo elingalinganiyo le-carbon steel kunye ne-alloy steel linqunyulwa ngokukhawuleza; Uhlobo lwe-YG uhlobo lwe-alloy enzima Kufanelekile ukujika ngokukrakra ekusikeni okuqhubekayo kwentsimbi etyhidiweyo, iintsimbi ezingenayo i-ferrous kunye ne-alloys yazo kunye nezixhobo ezingezizo zetsimbi, ukugqiba i-semi-finishing kunye nokugqiba kwi-intermittent cutting.
Kukho amazwe angaphezu kwama-50 ehlabathini avelisa i-carbide ene-cemented, kunye nesiphumo esipheleleyo se-27,000-28,000t-. Abavelisi abaphambili yi-United States, iRashiya, iSweden, iChina, iJamani, iJapan, i-United Kingdom, iFransi, njl njl. , ukhuphiswano lweemarike lunzima kakhulu. Ishishini laseTshayina lesamente le-carbide laqala ukumila ngasekupheleni kweminyaka yoo-1950. Ukusukela ngeminyaka yoo-1960 ukuya koo-1970, ishishini laseTshayina lesamente le-carbide lakhula ngokukhawuleza. Ekuqaleni kweminyaka yee-1990, umthamo wemveliso we-China we-cemented carbide ufikelele kwi-6000t, kwaye imveliso epheleleyo ye-carbide ene-cemented yafikelela kwi-5000t, okwesibini kuphela eRashiya nase-United States, ikwindawo yesithathu emhlabeni.
