Cemented carbide ndi aloyi wopangidwa ndi zinthu zolimba zazitsulo zowuma komanso zomangira zitsulo pogwiritsa ntchito zitsulo za ufa. Nthawi zambiri amapangidwa ndi zida zomangira zofewa (monga cobalt, faifi tambala, chitsulo kapena zosakaniza zomwe zili pamwambapa) kuphatikiza zida zolimba (monga tungsten carbide, molybdenum carbide, tantalum carbide, chromium carbide, vanadium carbide, titanium carbide kapena zosakaniza zake).
Simenti carbide ali mndandanda wa zinthu zabwino kwambiri, monga kuuma mkulu, kukana kuvala, mphamvu zabwino ndi kulimba, kukana kutentha, kukana dzimbiri, etc., makamaka kuuma kwake mkulu ndi kuvala kukana, amene amakhalabe kwenikweni osasintha ngakhale pa 500 ℃ ndipo akadali kuuma mkulu pa 1000 ℃. Muzinthu zathu wamba, kuuma kumachokera pamwamba mpaka pansi: sintered diamondi, cubic boron nitride, cermet, simenti carbide, chitsulo chothamanga kwambiri, ndipo kulimba kumachokera pansi mpaka pamwamba.
Cemented carbide chimagwiritsidwa ntchito monga zida kudula chida, monga kutembenuza zida, odula mphero, planers, kubowola, odula wotopetsa, etc., kudula kuponyedwa chitsulo, zitsulo sanali achitsulo, mapulasitiki, ulusi mankhwala, graphite, galasi, mwala ndi zitsulo wamba, komanso kudula kutentha zosagwira zitsulo, zitsulo zosapanga dzimbiri, mkulu manganese zovuta makina zitsulo ndi zitsulo zina zovuta makina, zitsulo ndi zitsulo.
Carbide yokhala ndi simenti imakhala yolimba kwambiri, mphamvu, kukana kuvala komanso kukana dzimbiri, ndipo imadziwika kuti "mano a mafakitale". Amagwiritsidwa ntchito popanga zida zodulira, zida zodulira, zida za cobalt ndi zida zosavala. Amagwiritsidwa ntchito kwambiri m'makampani ankhondo, zakuthambo, makina, zitsulo, kubowola mafuta, zida zamigodi, kulumikizana kwamagetsi, zomangamanga ndi zina. Ndi chitukuko cha mafakitale akumunsi, kufunikira kwa msika wa carbide simenti kukuchulukirachulukira. Ndipo m'tsogolomu, kupanga zida zamakono ndi zipangizo zamakono, kupita patsogolo kwa sayansi ndi luso lamakono ndi chitukuko chofulumira cha mphamvu za nyukiliya zidzakulitsa kwambiri kufunikira kwa mankhwala opangidwa ndi simenti ya carbide okhala ndi zipangizo zamakono komanso kukhazikika kwapamwamba.
Mu 1923, schlerter waku Germany adawonjezera 10% - 20% cobalt ku tungsten carbide ufa ngati binder, ndipo adapanga alloy yatsopano ya tungsten carbide ndi cobalt. Kuuma kwake ndi kwachiwiri kwa diamondi, yomwe ndi carbide yoyamba yopangira simenti padziko lapansi. Podula zitsulo ndi chida chopangidwa ndi alloy iyi, tsambalo lidzavala mofulumira, ndipo ngakhale tsambalo lidzasweka. Mu 1929, schwarzkov wa ku United States anawonjezera kuchuluka kwa ma carbides a tungsten carbide ndi titaniyamu carbide ku mapangidwe oyambirira, zomwe zinapangitsa kuti zida zodulira zitsulo zikhale bwino. Ichi ndi kupambana kwina m'mbiri ya chitukuko cha simenti ya carbide.
Carbide yokhala ndi simenti imathanso kugwiritsidwa ntchito popanga zida zobowola miyala, zida zamigodi, zida zobowolera, zida zoyezera, zida zosagwirizana, zomangira zitsulo, zomangira za silinda, zonyamulira zolondola, ma nozzles, nkhungu za Hardware (monga zojambulajambula za waya, zisankho za bawuti, nkhungu za mtedza, ndi magwiridwe antchito amtundu wapambuyo pang'onopang'ono. nkhungu).
M'zaka makumi awiri zapitazi, carbide yokhala ndi simenti yawonekeranso. Mu 1969, dziko la Sweden linapanga bwino chida cha titanium carbide. Gawo lapansi la chida ndi tungsten titaniyamu cobalt simenti carbide kapena tungsten cobalt simenti carbide. Makulidwe a titaniyamu carbide ❖ kuyanika pamwamba ndi ma microns ochepa, koma poyerekeza ndi aloyi zida za mtundu womwewo, moyo utumiki anawonjezera ndi nthawi 3, ndi kudula liwiro chawonjezeka ndi 25% - 50%. M'badwo wachinayi wa zida zokutira zidawonekera m'zaka za m'ma 1970, zomwe zitha kugwiritsidwa ntchito podula zida zomwe zimakhala zovuta kupanga makina.
