ʻenehana hana o ka Nickel Foam Metal
Huʻa nikala, i ʻike ʻia hoʻi he metala huʻa, he mea pūnaewele porous ʻekolu-dimensional i haku ʻia me ka nickel metala. Hōʻike ʻia e ke alakaʻi uila kiʻekiʻe, nā waiwai māmā, ke ʻano like, ke kūpaʻa maikaʻi loa i ka corrosion, a me ka porosity kiʻekiʻe, nickel Huʻa loaʻa nā noi nui i nā catalysts, nā cell wahie, nā mea pale electromagnetic, nā mea electrode, ka halihali, a me ke ʻenekinia kūkulu hale.
Nā ʻano hana hoʻomākaukau no ka sponge Nikala e komo pū me ka plating immersion, electroless nickel plating, a me ka vacuum nickel plating. ʻO ka electroless nickel plating ke ʻano nui no ka hana ʻana i ka nickel huʻa, me kāna kahe hana mua e pili ana i ka hoʻomākaukau ʻana i nā mea maka, ka mālama conductive, electroplating, calcination, reduction, a me ka annealing. Hāʻawi ka electroless nickel plating i nā pono e like me ke kūlana loea kiʻekiʻe, ka maʻalahi o ka hana, a me nā koi lako maʻalahi.Huʻa nikala i hana ʻia ma o kēia ʻano hana e hōʻike ana i nā ʻano e like me ke kūlike o nā pore maikaʻi loa a me ke kūpaʻa ʻana i ka pala. Me ka holomua mau ʻana o ka ʻenehana, ua mākaukau ka ʻoihana nickel foam no ka ulu wikiwiki ʻana.
ʻO ka nickel huʻa maʻamau he nickel metala a me nā dopants, me ka nickel metala e helu ana no kahi kokoke i 70% o nā kumukūʻai hana. Hāʻawi ka nickel metala i nā pono e like me ke kūpaʻa wela kiʻekiʻe, ka ductility maikaʻi loa, a me ka ikaika mechanical kiʻekiʻe, e hoʻohana nui ʻia ana i nā ʻāpana ʻoihana.
Loaʻa i ka huʻa nickel nā manaʻolana noi ākea ma nā ʻāpana he nui. I loko o nā cell wahie, lawelawe ia ma ke ʻano he mea hoʻololi papa bipolar a me ka electrocatalyst no nā cell wahie oxide paʻa (SOFCs), nā cell wahie membrane hoʻololi proton (PEMFCs), a me nā cell wahie carbonate i hoʻoheheʻe ʻia (MCFCs). I loko o nā mea electrode, lawelawe ka huʻa nickel ma ke ʻano he mea electrode no nā pila i nā mea uila, e like me nā kelepona paʻalima a me nā papa. Ke pōmaikaʻi nei mai ke koi mākeke ikaika, ʻo ka huʻa nikala ke hoʻomau nei ka ʻoihana e hoʻonui i kona hiki ke hoʻomohala.
