ʻAʻole ʻo ka metala ʻoi aku ka paʻakikī a loaʻa nā ʻano waiwai maikaʻi loa

ʻAʻole ʻo ka pahu metala ka metala paʻakikī, a hiki ke ʻokoʻa kona paʻakikī ma muli o ke ʻano metala a me ka hoʻolālā pore. No ka laʻana, hiki i ka pahu tungsten ke hiki i kahi paʻakikī Vickers o 600, ʻoiaipahu aluminiHe haʻahaʻa ka paʻakikī, 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.

ʻOi aku ka maikaʻi o ka hana ʻana o ka pahu metala
ʻOiaihuʻa metalaʻaʻole ʻoi aku ka paʻakikī, aia nō ka nui o nā 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 he mea hana māmā i ka aerospace a me nā noi automotive.
2, ʻO ka hoʻoheheʻe ʻana i ka ikehu: ʻO ke ʻano pore o ka pahu metala e hiki ai iā ia ke hoʻololi a hoʻopaʻa i ka ikehu i ka wā e hoʻokau ʻia ai i ke kaomi, no laila loaʻa iā ia nā mana anti-vibration a me nā anti-collision.
3, nā waiwai wela a me ka uila:huʻa metalahiki ke hoʻohana 'ia e like me ka maikaʻi thermal insulation a me thermal conductivity mea, akā, he maikai uila conductivity.
Ma muli o nā waiwai maikaʻi o luna, ʻo ka pahu metala ka nui o nā noi noi, e like me nā mea hoʻoheheʻe kaʻa kaʻa, nā mea hana aerospace, nā mea pōkā, nā reactors kemika a me nā māla ʻē aʻe.
ʻAʻole ʻo ka metala ʻoi aku ka paʻakikī, akā he māmā kona,ka hoʻopili ʻana i ka ikehu, ka hoʻokaʻawale ʻana i ka wela, ka wela a me ka conductivity uilaa me nā waiwai maikaʻi ʻē aʻe he nui, loaʻa kahi ākea o nā manaʻo noi.
