Carbide cimented bụ ihe alloy mere nke siri ike ogige nke refractory ọla na bonding ọla site uzuzu metallurgy usoro. A na-ejikarị ihe njikọ dị nro dị nro (dị ka cobalt, nickel, ígwè ma ọ bụ ngwakọta nke ihe ndị dị n'elu) gbakwunyere ihe ndị siri ike (dịka tungsten carbide, molybdenum carbide, tantalum carbide, chromium carbide, vanadium carbide, titanium carbide ma ọ bụ ngwakọta ha).
Cemented carbide nwere usoro nke magburu onwe Njirimara, dị ka elu ekweghị ekwe, eyi iguzogide, ezi ike na ike siri ike, okpomọkụ na-eguzogide, corrosion eguzogide, wdg, karịsịa ya elu ekweghị ekwe na eyi iguzogide, nke na-anọgide ihu ọma na-agbanweghi ọbụna na 500 ℃ na ka nwere elu ekweghị ekwe na 1000 ℃. N'ihe anyị na-ahụkarị, ike siri ike site na elu ruo ala: diamond sintered, cubic boron nitride, cermet, cemented carbide, ígwè dị elu na-agba ọsọ, na ike si na ala ruo elu.
A na-eji carbide cemented eme ihe n'ọtụtụ ebe dị ka ihe eji egbutu ihe, dị ka ngwaọrụ ntụgharị, igwe na-egwe ọka, ndị na-akụ ihe, ndị na-egbutu osisi, ndị na-akụ ihe na-agwụ ike, wdg, maka ịcha igwe nkedo, ọla ndị na-adịghị ferrous, plastik, eriri kemịkalụ, graphite, iko, nkume na nchara nkịtị, yana kwa maka ịcha ígwè na-eguzogide okpomọkụ, igwe anaghị agba nchara, nnukwu manganese ígwè, ígwè ngwá ọrụ na ihe ndị ọzọ siri ike igwe.
Carbide cimented nwere nnukwu isi ike, ike, iyi nguzogide na nguzogide corrosion, a makwaara ya dị ka "ezé ụlọ ọrụ".

Na 1923, schlerter nke Germany gbakwunyere 10% - 20% cobalt na tungsten carbide ntụ ntụ dị ka ihe nkedo, ma mepụta ihe ọhụrụ alloy nke tungsten carbide na cobalt. Isi ike ya bụ nke abụọ na dayamọnd, nke bụ carbide simenti mbụ na-arụ n'ụwa. Mgbe ị na-eji ngwá ọrụ a na-eji ígwè na-egbutu ígwè, agụba ahụ ga-eyi ngwa ngwa, na ọbụna agụba ga-agbawa. N'afọ 1929, Schwarzkov nke United States gbakwunyere ụfọdụ carbide tungsten carbide na titanium carbide na nhazi mbụ, bụ nke mere ka arụmọrụ nke ngwá ọrụ ịkpụ ígwè dịkwuo mma. Nke a bụ ihe ọzọ rụzuru na akụkọ ihe mere eme nke cimented carbide mmepe.
A pụkwara iji carbide cimented mee ngwá ọrụ igwu nkume, ngwá ọrụ ndị na-egwupụta ihe, ihe ndị na-egwupụta ihe, ngwá ọrụ a na-atụ aro, akụkụ ndị na-eguzogide ọgwụ, ígwè abrasives, cylinder liners, nkenke bearings, nozzles, hardware ebu (dị ka waya ịbịaru ebu, bolt ebu, nut ebu, na dị iche iche fastener ebu. The magburu onwe arụmọrụ nke gara aga carbide eji nwayọọ nwayọọ dochie ígwè).
N'ime iri afọ abụọ gara aga, carbide cemented ekpuchikwara apụta. N'afọ 1969, Sweden rụpụtara ngwa ọrụ mkpuchi carbide titanium nke ọma. Mkpụrụ nke ngwá ọrụ ahụ bụ tungsten titanium cobalt cemented carbide ma ọ bụ tungsten cobalt cemented carbide. Ọkpụrụkpụ nke mkpuchi carbide titanium n'elu bụ naanị micron ole na ole, ma e jiri ya tụnyere ngwaọrụ alloy nke otu ika ahụ, a na-agbatị ndụ ọrụ site na ugboro 3, na mbelata ọsọ na-abawanye site na 25% - 50%. Ọgbọ nke anọ nke ngwaọrụ mkpuchi pụtara na 1970, nke a pụrụ iji belata ihe ndị siri ike igwe.
