Carbide yopangidwa ndi simenti imatanthauza zinthu zopangidwa ndi zitsulo zosakanikirana ngati matrix ndi chitsulo chosinthira ngati gawo lolumikizira, kenako n’kupangidwa ndi njira ya ufa wa metallurgy. Imagwiritsidwa ntchito kwambiri m’magalimoto, zamankhwala, zankhondo, chitetezo cha dziko, ndege, ndege ndi madera ena. Ndikofunikira kudziwa kuti chifukwa cha mitundu yosiyanasiyana ndi zomwe zili mu carbide ndi zolumikizira zitsulo zosakanikirana, mphamvu zakuthupi ndi zamakemikolo za carbide zokonzedwa ndi zosiyana, ndipo mphamvu zawo zamakanika ndi zakuthupi zimadalira kwambiri mtundu wa carbide yachitsulo. Malinga ndi zigawo zazikulu zosiyanasiyana, carbide yopangidwa ndi simenti ikhoza kugawidwa m’mitundu ya YT ndi YG.
Kuchokera pamalingaliro a tanthauzo, carbide yolimba ya YT imatanthauza carbide yolimba ya tungsten-titanium-cobalt, zigawo zazikulu ndi tungsten carbide, titanium carbide ndi cobalt, ndipo dzina la kampani ndi "YT" (“hard, titanium” mawu awiri oyamba a Chinese Pinyin). Imapangidwa ndi kuchuluka kwa titanium carbide, monga YT15, zomwe zikutanthauza kuti kuchuluka kwa titanium carbide ndi 15%, ndipo yotsalayo ndi carbide yolimba yokhala ndi tungsten carbide ndi cobalt. Carbide yolimba ya YG imatanthauza carbide yolimba ya tungsten-cobalt. Zigawo zazikulu ndi tungsten carbide ndi cobalt. Mwachitsanzo, YG6 imatanthauza tungsten-cobalt carbide yokhala ndi kuchuluka kwa cobalt kwapakati pa 6% ndipo yotsalayo ndi tungsten carbide.
Kuchokera pakuwona momwe zinthu zikuyendera, ma carbide onse a YT ndi YG okhala ndi simenti ali ndi mphamvu yopukutira, mphamvu yopindika komanso kulimba. Tiyenera kudziwa kuti kukana kutopa ndi kutentha kwa carbide yopangidwa ndi simenti ya YT ndi carbide yopangidwa ndi simenti ya YG ndi zosiyana. Yoyamba ili ndi mphamvu yotopa komanso kutentha kochepa, pomwe yomaliza ili ndi mphamvu yotopa komanso kutentha kochepa. Ndi yabwino. Kuchokera pakuwona momwe imagwiritsidwira ntchito, carbide yopangidwa ndi simenti ya YT ndi yoyenera kupotoza mozungulira, kupotoza mozungulira, kupota pang'ono, kupukuta mozungulira komanso kubowola malo osasunthika pamene gawo losagwirizana la chitsulo cha kaboni ndi chitsulo cha alloy limadulidwa pang'onopang'ono; alloy yolimba ya mtundu wa YG Ndi yoyenera kupotoza mozungulira chitsulo chopangidwa, zitsulo zopanda chitsulo ndi zitsulo zawo ndi zinthu zopanda chitsulo, kupota pang'ono ndi kutsiriza pang'onopang'ono.
Pali mayiko opitilira 50 padziko lonse lapansi omwe amapanga carbide yopangidwa ndi simenti, ndipo kuchuluka kwake ndi 27,000-28,000t-. Opanga akuluakulu ndi United States, Russia, Sweden, China, Germany, Japan, United Kingdom, France, ndi zina zotero. Msika wa carbide wopangidwa ndi simenti padziko lonse lapansi uli wodzaza ndi zinthu zambiri. Mpikisano wamsika ndi woopsa kwambiri. Makampani opanga carbide yopangidwa ndi simenti ku China anayamba kupanga zinthu kumapeto kwa zaka za m'ma 1950. Kuyambira m'ma 1960 mpaka m'ma 1970, makampani opanga carbide yopangidwa ndi simenti ku China adakula mofulumira. Kumayambiriro kwa zaka za m'ma 1990, mphamvu yonse yopangira carbide yopangidwa ndi simenti ku China idafika 6000t, ndipo kuchuluka konse kwa carbide yopangidwa ndi simenti kudafika 5000t, yachiwiri ku Russia ndi United States, ili pa nambala 3 padziko lonse lapansi.
