O le carbide sima o se mea faʻapipiʻi e faia i faʻamaʻaʻa malo o uʻamea refractory ma uʻamea faʻapipiʻi e ala i le faʻaogaina o le paʻu. E masani ona faia i mea faʻapipiʻi vaivai (e pei o le cobalt, nickel, uʻamea poʻo se faʻafefiloi o mea o loʻo i luga) faʻatasi ai ma mea faigata (e pei o le tungsten carbide, molybdenum carbide, tantalum carbide, chromium carbide, vanadium carbide, titanium carbide poʻo latou faʻafefiloi).
O le carbide sima o loʻo i ai se faasologa o mea sili ona lelei, e pei o le maualuga o le maʻaʻa, faʻafefeteina, malosi lelei ma le faigata, faʻafefe vevela, faʻamaʻi faʻamaʻi, ma isi, aemaise lava lona malosi maualuga ma le ofuina o le teteʻe, lea e tumau pea e le suia e oʻo lava i le 500 ℃ ma o loʻo i ai pea le malosi maualuga i le 1000 ℃. I a tatou mea masani, o le maaa e mai le maualuga i lalo: taimane sintered, cubic boron nitride, cermet, carbide sima, uʻamea maualuga-saosaoa, ma le faigata mai le maualalo i le maualuga.
carbide sima e masani ona faʻaaogaina e pei o mea faigaluega faʻapipiʻi, e pei o le liliuina o mea faigaluega, milling cutters, planers, drill bits, cutters boring, ma isi, mo le tipiina o le uʻamea, uʻamea e le o le ferrous, palasitika, filo vailaʻau, graphite, tioata, maʻa ma le uamea masani, faʻapea foʻi mo le tipiina o le vevela, uamea stainless, uʻamea maualuga, uʻamea meafaigaluega ma isi mea faigata i masini.
Sima carbide e maualuga le maaa, malosi, ofuina teteʻe ma corrosion teteʻe, ma ua lauiloa o "nifo alamanuia". E faʻaaogaina e gaosia ai meafaigaluega tipi, tipi mea faigaluega, mea faigaluega cobalt ma vaega faʻafefete. E faʻaaogaina lautele i alamanuia a le militeri, aerospace, machining, metallurgy, suauʻu suauʻu, meafaigaluega maina, fesoʻotaʻiga eletise, fausiaina ma isi fanua. Faatasi ai ma le atinaʻeina o pisinisi i lalo, o loʻo faʻateleina le manaʻomia o maketi mo carbide sima. Ma i le lumanaʻi, o le gaosiga o auupega faʻatekonolosi ma meafaigaluega, o le alualu i luma o le faʻasaienisi ma tekonolosi faʻavavevave ma le televave o le atinaʻeina o le malosi faaniukilia o le a matua faateleina ai le manaʻoga mo oloa faʻamaʻi faʻamaʻi faʻatasi ma mea faʻatekonolosi maualuga ma mautu maualuga.
I le 1923, na faaopoopo ai e Schlerter o Siamani le 10% - 20% cobalt i le paʻu paʻu tungsten carbide e fai ma fusi, ma fausia ai se mea fou o le tungsten carbide ma cobalt. O lona ma'a'a e lona lua na'o taimane, o le ulua'i carbide sima fa'afoma'i i le lalolagi. Pe a tipi uʻamea i se meafaigaluega e faia i lenei mea faʻapipiʻi, o le a vave ona ofuina le lau, ma e oʻo lava i le lau o le a taʻe. I le 1929, schwarzkov o le Iunaite Setete na faʻaopoopoina se aofaʻi o carbide faʻapipiʻi o le tungsten carbide ma le titanium carbide i le uluaʻi fatuga, lea na faʻaleleia ai le faʻatinoga o meafaigaluega tipi uʻamea. O le isi lea matati'a i le tala faasolopito o le atina'eina o carbide sima.
carbide sima e mafai foi ona faaaoga e fai ai meafaigaluega eli maa, meafaigaluega eliina, meafaigaluega viliina, fuaina o mea, vaega e le ofuina, abrasives uʻamea, laina ogalaau, paʻu saʻo, nozzles, masini masini (e pei o uaea tusi molds, molds uʻamea, nut molds, ma faʻapipiʻi eseese molds.
I le luasefulu tausaga ua tuanaʻi, ua faʻaalia foʻi le carbide sima faʻapipiʻiina. I le 1969, na faʻamanuiaina e Suetena se meafaigaluega faʻapipiʻiina titanium carbide. Le substrate o le meafaigaluega o le tungsten titanium cobalt sima carbide po o le tungsten cobalt sima carbide. O le mafiafia o le titanium carbide coating i luga o le fogaeleele e na o ni nai microns, ae faʻatusatusa i meafaigaluega faʻapipiʻi tutusa, o le ola tautua e faʻalauteleina i le 3 taimi, ma le saoasaoa o le tipiina e 25% - 50%. O le lona fa o augatupulaga o meafaigaluega faʻapipiʻi na faʻaalia i le 1970s, lea e mafai ona faʻaaogaina e tipi ai mea e faigata ona faʻaaogaina.
