He aha ke ʻano o nā metala huʻi?

ʻO ka metala foamed, kahi ʻano mea metala hou me ka nui o nā pores o loko, ua loaʻa ka manaʻo nui i nā makahiki i hala. Ma muli o ke ʻano o ka metala a me ke kaʻina hana, hoʻokaʻawale ʻia nā metala foamed i nā ʻano like ʻole e like me ka alumini foam, nickel foam, a me ka titanium foam. ʻAʻole i loaʻa i kēia mau metala pua nā hiʻohiʻona o ka māmā, ka ikaika kiʻekiʻe, ka pale ʻana i ke ahi, a me ka acoustic a me ka thermal insulation akā hōʻike pū kekahi i ka mana nui no ka hoʻohana ʻana i nā kula he nui.
Aluminum Foam
ʻO ka pahu alumini kekahi o nā metala puaʻa, me ka alumini ka mea nui. Hana ʻia ia ma ka hui ʻana i ka alumini a i ʻole ke alumini alumini me kahi mea hoʻoheheʻe kikoʻī, ma hope o ke kaʻina hoʻoheheʻe kiʻekiʻe a me ka hoʻoulu ʻana. ʻO ka pahu alumini ka maikaʻi o ke kani-absorbing a me ka wela-insulating waiwai, no laila ua hoʻohana nui ʻia i ke kūkulu ʻana, ka lawe ʻana, a me nā māla ʻē aʻe. Eia kekahi, ʻo kāna mau hiʻohiʻona māmā a me ka ikaika kiʻekiʻe e hāʻawi iā ia i kahi pōmaikaʻi nui ma ke kahua aerospace.

Nikela Huhu
ʻO Nickel Foam kekahi metala koʻikoʻi me ka nickel ka mea nui. Loaʻa iā ia ka conductivity uila maikaʻi, ductility, a me ka pale ʻana i ka corrosion, a no laila he ākea ka nui o nā noi i ka electrochemistry, ʻoi aku hoʻi i nā mea uila uila. Eia kekahi, ʻo ke ʻano porous o ka nickel foam e lilo ia i mea lawe catalyst maikaʻi loa, e pāʻani ana i kahi kuleana nui i nā hopena kemika.

ʻAha Titanium
ʻO ka pahu Titanium he metala puaʻa me ka titanium ka mea nui. ʻO ka Titanium ponoʻī he kūpaʻa maikaʻi loa i ka corrosion, ikaika kiʻekiʻe, a me ka haʻahaʻa haʻahaʻa, no laila he nui nā noi o ka titanium foam i ka aerospace, ʻenekinia moana, a me nā kahua kiʻekiʻe. I ka manawa like, hāʻawi pū kona ʻano porous i ka titanium foam i ka biocompatibility maikaʻi, no laila ke hōʻike nei i ka mana nui i ka papa biomedical.

Ma ke ʻano he ʻano mea hou, foamed metala, me kona ʻano kūʻokoʻa a me nā waiwai hana, ua hōʻike i kahi ākea o nā hiʻohiʻona noi ma nā ʻano he nui. Me ka hoʻomau mau ʻana o ka ʻepekema a me ka ʻenehana, manaʻo ʻia ʻo foamed metala e pāʻani i kāna mau pono kūʻokoʻa i nā kula hou aʻe a hāʻawi i nā kōkua nui i ka hoʻomohala ʻana i ke kaiāulu kanaka.
