Cemented carbide wani gami abu ne da aka yi da wuya mahadi na refractory karafa da bonding karafa ta foda karfe tsari. Yawancin lokaci ana yin shi da kayan haɗin kai masu laushi (kamar cobalt, nickel, ƙarfe ko cakuda abubuwan da ke sama) da kayan aiki masu wuya (kamar tungsten carbide, molybdenum carbide, tantalum carbide, chromium carbide, vanadium carbide, titanium carbide ko gaurayawan su).
Cemented carbide yana da jerin kyawawan kaddarorin, kamar babban taurin, sa juriya, ƙarfi mai kyau da tauri, juriya mai zafi, juriya na lalata, da dai sauransu, musamman taurinsa mai ƙarfi da juriya, wanda ya kasance ba canzawa ko da a 500 ℃ kuma har yanzu yana da babban taurin a 1000 ℃. A cikin kayanmu na yau da kullun, taurin yana daga sama zuwa ƙasa: lu'u-lu'u mai laushi, cubic boron nitride, cermet, carbide cemented, ƙarfe mai sauri, kuma taurin yana daga ƙasa zuwa babba.
Cemented carbide ne yadu amfani da yankan kayan aiki kayan, kamar juya kayan aikin, milling cutters, planers, rawar soja rago, m cutters, da dai sauransu, domin yankan jefa baƙin ƙarfe, wadanda ba ferrous karafa, robobi, sinadaran zaruruwa, graphite, gilashin, dutse da talakawa karfe, da kuma ga yankan zafi-resistant karfe, bakin karfe, high manganese karfe, kayan aiki karfe da sauran wuya inji kayan.
Carbide da aka yi da siminti yana da tsayin daka, ƙarfi, juriya da juriya na lalata, kuma ana kiransa da "haƙoran masana'antu". Ana amfani da shi don kera kayan aikin yanke, kayan aikin yanke, kayan aikin cobalt da sassa masu jurewa. Ana amfani da shi sosai a masana'antar soji, sararin samaniya, injina, karafa, hako mai, kayan aikin hakar ma'adinai, sadarwar lantarki, gine-gine da sauran fannoni. Tare da haɓaka masana'antu na ƙasa, buƙatun kasuwa na simintin carbide yana ƙaruwa. Kuma a nan gaba, kera manyan makamai da na'urori, da ci gaban kimiyya da fasaha na zamani, da saurin bunkasuwar makamashin nukiliya za su kara yawan bukatar kayayyakin siminti na siminti tare da fasahohi masu inganci da kwanciyar hankali.
A cikin 1923, schlerter na Jamus ya ƙara 10% - 20% cobalt zuwa tungsten carbide foda a matsayin mai ɗaure, kuma ya ƙirƙira sabon gami na tungsten carbide da cobalt. Taurinsa shine na biyu kawai bayan lu'u-lu'u, wanda shine carbide na farko da aka yi da siminti a duniya. Lokacin yankan karfe tare da kayan aikin da aka yi da wannan gami, ruwan zai yi sauri da sauri, har ma da ruwan wukake zai tsage. A shekara ta 1929, Schwarzkov na Amurka ya ƙara wani adadin fili na tungsten carbide da titanium carbide zuwa ainihin abun da ke ciki, wanda ya inganta aikin kayan aikin yanke karfe. Wannan wata nasara ce a tarihin ci gaban siminti na siminti.
Hakanan za'a iya amfani da simintin carbide don yin kayan aikin hako dutse, kayan aikin hako ma'adinai, kayan aikin hakowa, kayan aikin aunawa, sassa masu jurewa, abrasives na ƙarfe, silinda liners, daidaitattun bearings, nozzles, gyare-gyaren kayan aiki (kamar zanen zanen waya, ƙwanƙwaran ƙwanƙwasa, ƙwanƙwasa goro, da nau'ikan gyare-gyaren fastener daban-daban. Kyakkyawan aiki na siminti a hankali ya maye gurbin siminti na baya).
A cikin shekaru ashirin da suka gabata, simintin siminti shima ya bayyana. A cikin 1969, Sweden ta sami nasarar haɓaka kayan aiki mai rufi na titanium carbide. Tushen kayan aikin shine tungsten titanium cobalt cimined carbide ko tungsten cobalt cimined carbide. Kauri na titanium carbide shafi a kan surface ne kawai 'yan microns, amma idan aka kwatanta da gami kayan aikin da iri guda iri, da sabis rayuwa yana kara da sau 3, da yankan gudun ya karu da 25% - 50%. Ƙarni na huɗu na kayan aikin shafa sun bayyana a cikin 1970s, waɗanda za a iya amfani da su don yanke kayan da ke da wuyar inji.
