I-carbide enesimenti ibhekisa kwizinto ezenziwe ngentsimbi enokukhanyelwa njenge-matrix kunye ne-transition metal njenge-binder phase, ize yenziwe ngendlela ye-powder metallurgy. Isetyenziswa kakhulu kwiimoto, kwezonyango, emkhosini, kukhuselo lwesizwe, kwi-aerospace, kwi-aircraft nakwamanye amasimi. . Kubalulekile ukuqaphela ukuba ngenxa yeentlobo ezahlukeneyo kunye nomxholo wee-carbide zesinyithi ezingenakukhanyelwa kunye nee-binder, iipropati zomzimba nezekhemikhali zee-carbide ezilungisiweyo ze-cemented nazo zahlukile, kwaye iipropati zazo zoomatshini nezomzimba zixhomekeke kakhulu kuhlobo lwe-carbide yesinyithi. Ngokwezinto eziphambili ezahlukeneyo, i-carbide enesimenti inokwahlulwa ibe yi-YT type kunye ne-YG type cemented carbide.
Ngokwembono yenkcazo, i-carbide eqinisiweyo yohlobo lwe-YT ibhekisa kwi-carbide eqinisiweyo yohlobo lwe-tungsten-titanium-cobalt, izinto eziphambili yi-tungsten carbide, i-titanium carbide kunye ne-cobalt, kwaye igama lophawu yi-"YT" ("i-hard, titanium" amagama amabini isimaphambili se-Chinese Pinyin). Yenziwe ngumxholo ophakathi we-titanium carbide, njenge-YT15, oko kuthetha ukuba umxholo ophakathi we-titanium carbide yi-15%, kwaye okuseleyo yi-carbide eqinisiweyo enomxholo we-tungsten carbide kunye nomxholo we-cobalt. I-carbide eqinisiweyo yohlobo lwe-YG ibhekisa kwi-carbide eqinisiweyo yohlobo lwe-tungsten-cobalt. Izinto eziphambili yi-tungsten carbide kunye ne-cobalt. Umzekelo, i-YG6 ibhekisa kwi-carbide ye-tungsten-cobalt enomxholo ophakathi we-cobalt we-6% kwaye okuseleyo yi-tungsten carbide.
Ngokwembono yokusebenza, zombini ii-carbides zesamente ze-YT kunye ne-YG zisebenza kakuhle ekugayeni, amandla okugoba kunye nokuqina. Kufuneka kuqatshelwe ukuba ukumelana nokuguguleka kunye nokuqhuba ubushushu kwe-carbide yesamente yohlobo lwe-YT kunye ne-carbide yesamente yohlobo lwe-YG zichasene. Eyokuqala inokumelana nokuguguleka okungcono kunye nokuqhuba ubushushu okungekho mthethweni, ngelixa eyesibini inokumelana nokuguguleka okubi kunye nokuqhuba ubushushu. Ilungile. Ngokwembono yesicelo, i-carbide yesamente yohlobo lwe-YT ifanelekile ekujikeni okurhabaxa, ekuplanini okurhabaxa, ekugqibeni okuncinci, ekugayeni okurhabaxa kunye nokubhoboza umphezulu ongaqhubekiyo xa icandelo elingalinganiyo lesinyithi sekhabhoni kunye nentsimbi ye-alloy lisikwa ngokuphindaphindiweyo; i-alloy enzima yohlobo lwe-YG ifanelekile ekujikeni okurhabaxa ekusikeni okuqhubekayo kwesinyithi esityhidiweyo, iintsimbi ezingezizo iintsimbi kunye nee-alloys zazo kunye nezinto ezingezizo iintsimbi, ekugqityweni okuncinci kunye nokugqiba ekusikeni okuncinci.
Kukho amazwe angaphezu kwama-50 ehlabathini avelisa i-carbide eqinisiweyo, enemveliso iyonke eyi-27,000-28,000t-. Abavelisi abaphambili yi-United States, iRashiya, iSweden, iTshayina, iJamani, iJapan, i-United Kingdom, iFrance, njl. Imarike ye-carbide eqinisiweyo yehlabathi igcwele kakhulu. , ukhuphiswano lwemarike lunamandla kakhulu. Ishishini le-carbide eqinisiweyo laseTshayina laqala ukubonakala ngasekupheleni kweminyaka yoo-1950. Ukususela kwiminyaka yoo-1960 ukuya koo-1970, ishishini le-carbide eqinisiweyo laseTshayina lakhula ngokukhawuleza. Ekuqaleni kweminyaka yoo-1990, amandla emveliso iyonke ye-carbide eqinisiweyo yaseTshayina afikelela kwi-6000t, kwaye imveliso iyonke ye-carbide eqinisiweyo ifikelele kwi-5000t, yesibini emva kweRashiya ne-United States, ikwindawo yesithathu kwihlabathi liphela.
