Ke ʻano o ka
ʻO ka paʻa ma lalo o ka mahana maʻamau a me ke kaomi. Hōʻalo i nā mea hoʻoheheʻe hao. Paakiki ʻo Micro Vickers (hoʻouka 50g) 2944kg / mm, he wahi hoʻoheheʻe kiʻekiʻe (2830 ℃). Hoʻohana Hiki ke hoʻohana ʻia e like me ka hoʻomaʻemaʻe palaoa i ke kinikini paʻa, mea hana ʻoki a me nā ʻoihana hana kila, hiki ke hoʻomaikaʻi maikaʻi i nā waiwai o ke kinikini.
Hoʻohana ʻia no ka ʻoki ʻana i nā mea paʻa paʻa, e hana ana i nā kiʻi ʻino paʻa - a me ke kiʻi semiconductor
ʻO ka vanadium carbide me ka paʻakikī kiʻekiʻe, ka pae hoʻoheheʻe a me ka ikaika o ke ana wela a me nā ʻano maʻamau o ke kalapona metala hoʻololi, a me ka maikaʻi o ka conductivity a me ka conductivity thermal, no laila i ka hao a me ke kila metallurgy, paʻa paʻa, nā huahana uila, nā catalist a me nā mea hoʻoweliweli wela kiʻekiʻe a. nā kahua ʻē aʻe he laulā o nā noi. Ua hōʻike ʻia i loko o nā puke e hōʻoia i ke kūpaʻa thermodynamic o nā mea kāohi lāʻau like me ka hopena hopena, a ʻo VC> Mo2C> Cr3C2> NbC> TaC> TiC> ZrC. Hiki ke hoʻohana ʻia ka hoʻohui o ka vanadium carbide ma ke ʻano he paakiki e hoʻomaikaʻi nui i ka paʻakikī a me ke ola o ka carbide sima, a hoʻoliʻiliʻi i ka magnetization saturated, remanence, coerce magnetic force, magnetic product huahana, magnetic permeability a me Curie ka mahana o ka carbide sima e hana. kinikini hoʻoheheʻe ʻole.
Me ka hoʻonui ʻana o ka noi o ka carbide sima i nā mea kaua kiʻekiʻe a me nā pono hana, ka ʻepekema ʻoki a me ka ʻenehana a me ka ikehu nukelea, pono ia e hoʻonui hou i ka hana o ke aniani WC. ʻO ke ala ʻoi loa e hoʻomaʻemaʻe i kāna palaoa a hoʻomākaukau i ka ultrafine a i ʻole ʻo ka nanostruktur i hana ʻia i ka carbide sima. No ka nanometa i hoʻoheheʻe ʻia i ka pauka karbida, ulu ka palaoa ke hana ʻia ma 1 150. Inā kiʻekiʻe ke ana wela o ka mea kāohi, ʻaʻole ia he paʻakikī e pāʻani i kahi kuleana kaohi, akā ʻoi aku ka maikaʻi o ka hana o ka carbide sima. No laila, ʻoi aku ka wikiwiki o ka mea e pono ai nā mea hoʻopukapuka nano-palaoa, a ua hoʻomākaukau ka hoʻomākaukau ʻana o ka nano-vanadium carbide pauka i ka manaʻo o nā kānaka noiʻi he nui. Ke piʻi nei ka pilina o ke kalapona i ka oxygen me ka mahuahua o ka mahana, a ke emi nei ka pilina o nā metala like ʻole i ka oxygen me ka hoʻonui ʻana o ka mahana, hiki ke hoʻomākaukau ʻia ka metala a i ʻole ka carbide e ka hoʻēmi kalapona kalapona ma ke ana wela. Hiki ke hōʻemi i ke kalapona o nā huahana nui no CO, CO2, i ka huahana e nā hanana haumia haumia impurities. No laila, loaʻa i ke ʻano hoʻohaʻahaʻa carbothermal ke ʻano o ke kaʻina maʻalahi, maʻalahi ka loaʻa ʻana o nā mea maka, ka hana hou ʻana a pēlā aku, a he waiwai kūpono kiʻekiʻe.

ʻO ka vanadium carbide me ka paʻakikī kiʻekiʻe, ka pae hoʻoheheʻe a me ka ikaika o ke ana wela a me nā ʻano maʻamau o ke kalapona metala hoʻololi, a me ka maikaʻi uila a me ka conductivity thermal, no laila i ka hao a me ke kila metallurgy, paʻa paʻa, nā huahana uila, nā catalist a me nā mea hoʻoweliweli wela kiʻekiʻe. nā kahua ʻē aʻe he laulā o nā noi. Iwaena o lākou, hiki ke hoʻohui ʻia ka vanadium carbide i ka kila e hoʻomaikaʻi ai i nā pono ākea o ke kila e like me ke kūpaʻa o ka pale, ke kūpaʻa ʻaʻa, paʻakikī, ikaika, ductility, paakiki a me ka māluhiluhi luhi kūpale, a hiki ke hoʻohana ʻia ma ke ʻano he mea pale i nā ʻoki ʻokoʻa a komo i nā mea hana kūpaʻa. Hoʻohui ʻia, hoʻohana nui ʻia ka vanadium carbide ma ke ʻano he catalyst ma muli o kāna hana kiʻekiʻe, selectivity, kūpaʻa a me ke kūpaʻa ʻana i ka "catalyst poisoning" i nā hopena hydrocarbon. Hoʻohui ʻia, hiki ke hoʻohana ʻia ka vanadium carbide ma ke ʻano he kumu kalapona hou e synthesize i ke daimana. ʻO ke kuleana nui o ka vanadium carbide e hoʻohana ʻia ma ke ʻano he inhibitor palaoa ma ke kula o ka carbide ciment a me nā cermets, i hiki ke pale pono i ka ulu ʻana o nā hua WC i ke kaʻina hana sinter.
