Metal Foam - metala e hanu ana

Ma muli o kona hoʻolālā kūikawā, loaʻa iā ia nā waiwai kūikawā ma nā ʻano he nui. Ma keʻano he mea hoʻolālā, uaʻikeʻia e ke kaumaha māmā a me ka ikaika kiko'ī kiʻekiʻe; ma ke ʻano he mea hana, loaʻa iā ia nā ʻano kino like ʻole e like me ka porous, vibration damping, damping, sound-absorbing, sound insulation, heat dissipation, impact energy absorption, electromagnetic shielding a pēlā aku.
Metala puaaua hoʻomākaukau ʻia e ka pauka metallurgy method a me ka electroplating method, ka mea mua ma ka hoʻohui ʻana i ka mea hoʻohua i ka metala i hoʻoheheʻe ʻia e hana ai i ka metala pua; ʻo ka hope ma ke kaʻina hana electrodeposition ma ka ʻiʻo polyurethane foam skeleton i hoʻopili ʻia i loko o ka metala pahu.
Hoʻohui ʻia ke ʻano o ka pauka metallurgy e hana i ka metala puaʻa, hoʻohui ʻia i ka pauka puhi ʻana (e like me NH4Cl), sintering i ka volatilization mea puhi, e waiho ana i nā pores. Hiki ke hana ʻia nā metala metala me nā pores maʻamau a me ka porosity a hiki i ka 95% e ka electrochemical deposition, e komo pū me nā mea hao me nā metala a me nā mea hoʻoheheʻe e like me Cu, Ni, NiCrFe, ZnCu, NiCu, NiCrW, NiFe, a me nā metala ʻē aʻe e like me ka iwi iwi. Hoʻopili ʻia ka metala electrochemically i waiho ʻia ma ke kino porous i hoʻopili ʻia nā mea i waiho ʻia ma ke ʻano holoʻokoʻa, a ʻo ka ikaika a hiki i ka porous foam metala kiʻekiʻe me ka porosity kiʻekiʻe, hiki ke hoʻopiha ʻia me nā mea hou aku e like me nā catalysts a me nā electrolytes i loko. hoʻohana.
ʻO ka aluminika, ka nickel a me kā lākou mau mea hoʻoheheʻe he mea hoʻomaʻamaʻa metala, ʻo ia hoʻi, loaʻa i ka pahu keleawe kekahi wahi no ka hoʻomohala ʻana.
Aluminum huʻaa he māmā kona mau ʻāpana, me ka hoʻoheheʻe ʻana i ka leo, ka wela wela, ka vibration damping, absorption o ka hopena o ka ikehu a me nā hawewe electromagnetic a me nā ʻano ʻē aʻe, kūpono no nā missiles, nā mokulele a me kāna mau ʻāpana hoʻihoʻi o ka hopena o ka papa pale, nā pale kaʻa, nā mīkini uila uila. nā mea hoʻoheheʻe, ka uhi pale pale hawewe electromagnetic pulse.
ʻĀpana nikelaHe kiʻekiʻe ke kinoea permeability, kiʻekiʻe kikoʻī kikoʻī a me ka capillary ikaika ma muli o kona hoʻopili ʻia ʻana o ka pore a me ka porosity kiʻekiʻe, a ua hoʻohana nui ʻia ma ke ʻano he mea hana no ka hana ʻana i nā kānana wai, atomizers, catalytic converters, pā uila electrode a me nā mea hoʻololi wela.
Huʻa keleaweHe maikaʻi ka conductivity a me ka ductility, a ʻoi aku ka haʻahaʻa o ke kumukūʻai hoʻomākaukau ma mua o ka nickel foam, ʻoi aku ka maikaʻi o ka conductivity, hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā mea electrode maikaʻi ʻole (carrier), nā mea lawe catalyst a me nā mea pale electromagnetic. ʻO ka mea nui, ʻo ka pahu keleawe no nā pā e like me nā mea electrode substrate, he mau mea maikaʻi loa, akā ma muli o ke kūpaʻa ʻana o ke keleawe ʻaʻole maikaʻi e like me ka nickel, no laila e kaupalena ʻia kekahi o kāna mau noi.
Ua hoʻohana lōʻihi ʻia kēia mea ma ke ʻano he kumu kumu no nā mea hoʻopili mokulele. I loko o ka aerospace a me ka missile 'oihana, hiki ke hana i loko o ka sanwiti amo nā mea, e like me ka eheu metala iwi o ke kino kākoʻo, missile ihu cone o ka pūpū o ka kiʻekiʻe-mehana hāʻule o ke kino kākoʻo (no ka maikaʻi thermal. conductivity) a me ka pae pae ʻana o ka mokulele. I ke kūkulu ʻia ʻana, pono ʻia ka metala puaʻa no ka hana ʻana i nā mea māmā, paʻakikī, pale ahi, railings a i ʻole nā ​​​​mea kākoʻo no kēia mau mea. ʻO ke alapine kiʻekiʻe, ka wikiwiki kiʻekiʻe a me ka hoʻohaʻahaʻa ʻana o nā mea hoʻokiʻekiʻe hou e pono ai i nā hale māmā me nā waiwai ʻelua e hoʻemi i ka ikehu a me nā ukana e hōʻemi i ka hoʻohana ʻana i ka ikehu. ʻO ka cushioning kekahi o ka hoʻohana nui ʻana i ka metala foam, pono e loaʻa i ka hiki ke hoʻomoʻi i ka ikehu aʻo ka mālama ʻana i ka ikaika kiʻekiʻe e hana ana i ka mea i pale ʻia ma lalo o ka palena o ka hana ʻino.
