spherical kiʻekiʻe maʻemaʻe niobium carbide pauka
Hōʻike huahana
ʻO ka pauka Niobium carbide he pauka ʻeleʻele i haku nui ʻia o nā mea niobium a me carbon.Hoʻohana nui ʻia ka pauka Niobium carbide i ka carbide cemented, nā mea superhard, ʻenehana wela kiʻekiʻe a me nā ʻenehana uila a me nā māla ʻē aʻe.Ma ke kahua o ka carbide cemented, ʻo ka niobium carbide pauka kekahi o nā mea waiwai nui o ka carbide cemented, hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā mea hana cemented carbide, molds, etc. nā mea paʻa loa, e like me ke daimana a me ka cubic boron nitride;Ma ke kahua o ka ʻenehana wela wela, hiki ke hoʻohana ʻia ka pauka niobium carbide e hana i ka umu wela kiʻekiʻe, ke kiʻekiʻe wela wela, a me nā mea ʻē aʻe. ma.ʻO ka pauka Niobium carbide he mea hoʻohui koʻikoʻi, me ka helu heheʻe kiʻekiʻe, ka paʻakikī a me ka paʻa a me nā mea maikaʻi ʻē aʻe, hoʻohana nui ʻia i ka carbide cemented, nā mea superhard, ka ʻenehana wela kiʻekiʻe a me ka ʻenehana uila.

Ua haʻi aku ʻo Sem
Pūnaehana hoʻomalu maikaʻi
He ʻōnaehana koʻikoʻi ko Huarui.Ho'āʻo mua mākou i kā mākou huahana ma hope o ka hoʻopau ʻana i kā mākou hana, a hoʻāʻo hou mākou ma mua o kēlā me kēia lawe ʻana, ʻo ia hoʻi ka laʻana.A inā makemake ʻoe, makemake mākou e ʻae i ka ʻaoʻao ʻekolu e hoʻāʻo.ʻOiaʻiʻo inā makemake ʻoe, hiki iā mākou ke hāʻawi i kahi laʻana iā ʻoe e hoʻāʻo.
Hoʻopaʻa ʻia kā mākou huahana huahana e Sichuan Metallurgical Institute a me Guangzhou Institute of Metal Research.Hiki i ka hui lōʻihi me lākou ke mālama i ka manawa hoʻāʻo nui no nā mea kūʻai aku.
