ʻO ka carbide Cemented e pili ana i kahi mea hao i hana ʻia me ka pūhui metala refractory e like me ka matrix a me ka metala hoʻololi e like me ke ʻano binder, a laila hana ʻia e ke ʻano metallurgy pauka. Hoʻohana nui ʻia ia i ka kaʻa, ka lāʻau lapaʻau, ka pūʻali koa, ka pale aupuni, aerospace, aviation a me nā kula ʻē aʻe. . Pono e hoʻomaopopo ʻia ma muli o nā ʻano like ʻole a me nā mea i loko o nā carbide metala refractory a me nā mea hoʻopaʻa, ʻokoʻa nā ʻano kino a me nā kemika o nā carbide cemented i hoʻomākaukau ʻia, a ʻo kā lākou mau ʻano mechanical a me ke kino e hilinaʻi nui ʻia i ke ʻano o ka carbide metala. Wahi a nā ʻāpana nui like ʻole, hiki ke hoʻokaʻawale ʻia ka carbide cemented i ke ʻano YT a me ka YG type cemented carbide.
Mai ka manaʻo wehewehe, ʻo YT-type cemented carbide e pili ana i ka tungsten-titanium-cobalt-type cemented carbide, nā mea nui he tungsten carbide, titanium carbide a me ka cobalt, a ʻo ka inoa inoa ʻo "YT" ("paʻakikī, titanium" ʻelua huaʻōlelo Chinese Pinyin prefix) Ua haku ʻia ʻo ia me ka awelika maʻiʻo o ka titanium carbide, e like me YT15, ʻo ia hoʻi ʻo ka awelika o ka titanium carbide he 15%, a ʻo ke koena he carbide cemented me ka tungsten carbide a me ka ʻike cobalt. ʻO YG-type cemented carbide e pili ana i ka tungsten-cobalt-type cemented carbide. ʻO nā mea nui he tungsten carbide a me ka cobalt. No ka laʻana, pili ʻo YG6 i ka tungsten-cobalt carbide me ka awelika cobalt content o 6% a ʻo ke koena he tungsten carbide.
Mai ka manaʻo o ka hana, ʻo ka YT a me ka YG cemented carbide he hana wili maikaʻi, ka ikaika kulou a me ka paʻakikī. Pono e hoʻomaopopo ʻia ʻo ke kūʻē ʻana o ka ʻaʻahu a me ka conductivity thermal o YT-type cemented carbide a me YG-type cemented carbide i kū'ē. ʻOi aku ka maikaʻi o ka pale ʻana i ka ʻaʻahu a me ka conductivity thermal maikaʻi ʻole, ʻoiai ʻoi aku ka maikaʻi o ka pale ʻana i ka lole a me ka conductivity thermal. he maikai. Mai ka manaʻo o ka noi, ʻo YT type cemented carbide he kūpono no ka huli ʻana, ka hoʻolālā ʻino, ka semi-finishing, ka wili ʻana a me ka ʻeli ʻana o ka ʻili discontinuous ke ʻoki ʻia ka ʻāpana like ʻole o ke kila kalapona a me ke kila kila; ʻO YG type hard alloy He kūpono ia no ka hoʻohuli ʻana i ka ʻoki mau ʻana o ka hao, nā metala non-ferrous a me kā lākou mau mea hoʻohui a me nā mea non-metallic, semi-hoʻopau a hoʻopau i ka ʻoki intermittent.
Aia ma mua o 50 mau ʻāina ma ka honua e hana ana i ka carbide cemented, me ka huina o 27,000-28,000t-. ʻO nā mea hana nui ʻo ʻAmelika Hui Pū ʻIa, Lūkia, Suedena, Kina, Kelemānia, Iapana, United Kingdom, Farani, a me nā mea ʻē aʻe. , ikaika loa ka hoʻokūkū makeke. Ua hoʻomaka ka ʻoihana carbide cemented ma Kina i ka hopena o nā makahiki 1950. Mai ka makahiki 1960 a hiki i ka makahiki 1970, ua ulu wikiwiki ka ʻoihana carbide cemented o Kina. I ka makahiki mua o 1990, hiki i ka 6000t ka nui o ka hana o ka carbide cemented a Kina, a hiki i ka 5000t ka huina o ka carbide cemented, ʻelua wale nō ma Rusia a me ʻAmelika Hui Pū ʻIa, ʻo ia ke kolu o ka honua.
