ʻO ke carbide sima e pili ana i kahi mea hui i hana ʻia me ka hui metala refractory e like me ka matrix a me ka metala hoʻololi e like me ka pae hoʻopaʻa, a laila hana ʻia e ke ʻano metallurgy pauka. Hoʻohana nui ʻia ia i nā kaʻa, nā lāʻau lapaʻau, nā koa, nā pale kaua aupuni, nā aerospace, nā mokulele a me nā ʻoihana ʻē aʻe. . He mea kūpono ke hoʻomaopopo ʻana ma muli o nā ʻano like ʻole a me nā ʻano o nā carbides metala refractory a me nā mea hoʻopaʻa, ʻokoʻa hoʻi nā waiwai kino a me nā kemika o nā carbides sima i hoʻomākaukau ʻia, a ʻo kā lākou mau waiwai mechanical a me ke kino e pili nui ana i ke ʻano o ka carbide metala. Wahi a nā ʻāpana nui like ʻole, hiki ke hoʻokaʻawale ʻia ke carbide sima i ke ʻano YT a me ke ʻano YG cemented carbide.
Mai ka manaʻo wehewehe, ʻo ka carbide cemented ʻano YT e pili ana i ka carbide cemented ʻano tungsten-titanium-cobalt, ʻo nā mea nui he tungsten carbide, titanium carbide a me cobalt, a ʻo ka inoa inoa ʻo "YT" ("paʻakikī, titanium" ʻelua mau huaʻōlelo Kina Pinyin prefix) Ua haku ʻia ia me ka awelika o ka titanium carbide, e like me YT15, ʻo ia hoʻi ka awelika o ka titanium carbide he 15%, a ʻo ke koena he carbide cemented me ka tungsten carbide a me ka cobalt. ʻO ka carbide cemented ʻano YG e pili ana i ka carbide cemented ʻano tungsten-cobalt. ʻO nā mea nui he tungsten carbide a me cobalt. No ka laʻana, ʻo YG6 e pili ana i ka tungsten-cobalt carbide me ka awelika o ka cobalt o 6% a ʻo ke koena he tungsten carbide.
Mai ka manaʻo hana, loaʻa i nā carbides sima YT a me YG ka hana wili maikaʻi, ka ikaika kūlou a me ka paʻakikī. Pono e hoʻomaopopo ʻia he ʻokoʻa ke kūpaʻa ʻaʻahu a me ka conductivity thermal o ka carbide sima ʻano YT a me ka carbide sima ʻano YG. ʻOi aku ka maikaʻi o ke kūpaʻa ʻaʻahu o ka mua a me ka conductivity thermal maikaʻi ʻole, ʻoiai ʻo ka hope he kūpaʻa ʻaʻahu maikaʻi ʻole a me ka conductivity thermal. He maikaʻi ia. Mai ka manaʻo o ka noi, kūpono ka carbide sima ʻano YT no ka huli ʻino, ka hoʻolālā ʻino, ka hoʻopau hapa, ka wili ʻino a me ka wili ʻana o ka ʻili discontinuous i ka wā e ʻoki pinepine ʻia ai ka ʻāpana like ʻole o ke kila kalapona a me ke kila alloy; ʻO ka alloy paʻakikī ʻano YG He kūpono ia no ka huli ʻino i ka ʻoki mau ʻana o ka hao i hoʻolei ʻia, nā metala non-ferrous a me kā lākou mau mea alloys a me nā mea non-metallic, semi-finishing a me ka hoʻopau ʻana i ka ʻoki intermittent.
Aia ma mua o 50 mau ʻāina ma ka honua e hana ana i ka carbide sima, me ka huina o 27,000-28,000t-. ʻO nā mea hana nui ʻo ʻAmelika Hui Pū ʻIa, Rusia, Suedena, Kina, Kelemānia, Iapana, United Kingdom, Palani, a pēlā aku. Ua piha loa ka mākeke carbide sima o ka honua. , he ikaika loa ka hoʻokūkū mākeke. Ua hoʻomaka ka ʻoihana carbide sima o Kina e hoʻokumu i ke ʻano i ka hopena o nā makahiki 1950. Mai nā makahiki 1960 a hiki i nā makahiki 1970, ua ulu wikiwiki ka ʻoihana carbide sima o Kina. I ka hoʻomaka ʻana o nā makahiki 1990, ua hōʻea ka huina o ka hana ʻana o Kina i ka carbide sima i 6000t, a ua hōʻea ka huina o ka hana ʻana o ka carbide sima i 5000t, ʻo ka lua wale nō ma hope o Rusia a me ʻAmelika Hui Pū ʻIa, ʻo ia ke kolu o ka honua.
