spherical kiʻekiʻe maʻemaʻe niobium carbide pauka
Hōʻike huahana
ʻO ka pauka Niobium carbidehe ʻeleʻele māmā a he ʻulaʻula metala kona.I nā ʻoihana ʻenehana, hiki ke hoʻohana ʻia ka pauka niobium carbide e hana i ka cermet, nā ʻāpana wela a me ka carbide cemented, a hiki ke hoʻohana ʻia i mea hoʻohui i ka carbide cemented, hiki ke hoʻomaikaʻi nui i ka paʻakikī o ka wela a me ke kūpaʻa ʻana o ka wela, ka pale ʻana i ka wela, a me ka pale ʻana o ka oxidation o ka carbide cemented.Eia kekahi, hiki ke hoʻohana ʻia ka niobium carbide e hana i nā mea ʻokiʻoki, me ka paʻakikī wela maikaʻi, ka pale ʻana i ka haʻalulu a me ka pale ʻana o ka thermal oxidation.

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.
