ʻAʻole ʻo Metal Foams ka metala paʻakikī loa a he nui nā waiwai maikaʻi loa

ʻIke ʻia ʻo Metal Foams
Pua metalaʻO nā mea i loaʻa i nā ʻāpana honeycomb o nā hale metala me kahi degere o ka porosity i māmā, ʻoi loa ka ikehu, thermally a me ka uila. Hiki ke hoʻopaʻa ʻia nā Metal Foams i ka metala i hoʻohana ʻia, ka hana ʻana, a me ka hoʻolālā pore, ka hopena i nā ʻano waiwai like ʻole a me nā ʻano noi like ʻole me nā koi like ʻole.

ʻOoleʻa metala ʻōhū
ʻAʻole nā ​​metala ʻoi aku ka paʻakikī o ka huʻa metala; Hiki ke ʻokoʻa ko lākou paʻakikī ma muli o ke ʻano metala a me ka hoʻolālā pore. No ka laʻana, hiki i ka pahu tungsten ke hōʻea i ka paʻakikī o Vickers o 600, ʻoiai ʻoi aku ka haʻahaʻa o ka pahu alumini ma ka unahi paʻakikī, maʻamau ma kahi o HV50. ʻO ka ʻokoʻa, hiki i nā daimana superhard i hoʻohui ʻia i nā puʻe kiʻekiʻe a me nā mahana ke hiki i kahi paʻakikī Vickers ma kahi o 5,000, ʻoi aku ia ma mua o ʻumi mau manawa o ka paʻakikī o nā huʻa metala.

ʻO nā waiwai maikaʻi loa o nā pahu metala
ʻOiai ʻaʻole ʻoi aku ka paʻakikī o ka pahu metala, loaʻa nō nā ʻano waiwai maikaʻi loa. ʻo kahi laʻana:
1, māmā: ma muli o kona ʻano pore, he haʻahaʻa haʻahaʻa loa ka pahu metala, ʻoi aku ka liʻiliʻi ma mua o 0.5 g / cm3, no laila hiki ke hoʻohana ʻia ma ke ʻano hemea hana māmāi ka aerospace a me nā noi kaʻa.
2、Highly energy-absorbing: The pore structure of the metal foam e ʻae iā ia e deform a hoʻopaʻa i ka ikehu ke hoʻokau ʻia i ke kaomi, no laila he maikaʻi loa ka anti-vibration a me ka anti-collision.
3, nā mea wela a me nā uila: hiki ke hoʻohana ʻia ka pahu metala e like me ka insulation thermal maikaʻi a me nā mea conductivity thermal, akā maikaʻi nō hoʻi ka conductivity uila.

Ma muli o nā waiwai maikaʻi ma luna,huʻa metalaLoaʻa iā ia kahi ākea o nā manaʻo noiʻi, e like me nā mea hoʻoheheʻe haʻalulu kaʻa, nā ʻāpana hana aerospace, nā mea pale pale, nā mea hoʻokalakupua kemika, a me nā kahua ʻē aʻe.
