Pauka WC i hoʻonohonoho ʻia nano / Nano-tungsten carbide (WC 50nm 99.9%)
Nā hiʻohiʻona nui oʻO ka pauka WC nanostructured a me WC i hoʻomākaukau ʻia e kahi ʻano hana kūikawā, maʻemaʻe kiʻekiʻe, ka nui like, ka hoʻopuehu maikaʻi, ka hana ʻana o nā mea maka carbide cemented, hiki i ka pauka nano tungsten carbide ke hana i ka carbide he nui nā ʻano maikaʻi loa, ʻo kona kiko heheʻe 2860 ° C ± 50 ° C, kiko paila 6000 ° C, hiki ʻole ke hoʻoheheʻe ʻia i ka wai anuanu, waikawa ikaika, paʻakikī kiʻekiʻe, modulus elastic kiʻekiʻe. ʻIke ʻia ʻo Tungsten carbide he mōʻī paʻakikī, aia nā ʻano paʻakikī e hoʻohui i ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻana i ka corrosion, ke kiʻekiʻe o ka mahana a me nā ʻano ʻē aʻe.
Hoʻohana ʻia ka 1 nm tungsten carbide i nā mea hui pū ʻia, ʻo ka mea maka nui e hoʻomaikaʻi i kāna hana: ʻo ka pauka hui o ka nano tungsten carbide - cobalt (WC-Co) ka hoʻomākaukau ʻana i ka carbide hana kiʻekiʻe a me ka uhi ʻana i ke kapa. ʻO ka pauka hui Nano-WC-Co i hoʻohana ʻia ma ke ʻano he mea uhi pale kapa i hōʻike i nā hopena maikaʻi loa, ʻo ka hoʻohana ʻana i ka hoʻoheheʻe wikiwiki a me ka hoʻomaʻalili wikiwiki o ka ʻenehana pīpī wela e hoʻomākaukau i nā uhi, mālama ʻia nā waiwai nano-structural o ka pauka, no laila e hoʻomaikaʻi nui i ka hana paʻakikī o ka uhi pale kapa alloy. ʻO ka hana kūloko o nā huahana pauka hui nano WC-Co, ua hoʻohana ʻia i ka hoʻomākaukau ʻana o ka carbide a me ka uhi pale kapa. E like me: nā mea ʻoki, nā kamepiula, nā mīkini a me nā ʻoihana ʻē aʻe.
ʻO ka mīkini ʻokiʻoki tungsten carbide ʻelua, ka hana ʻana i nā mea ʻokiʻoki kūpono no nā mea kūkulu umu wela kiʻekiʻe, nā mīkini jet, nā turbine kinoea, a me nā nozzles.
