Uea Kū'ē Hoʻomehana Uila Fe-Cr-Al

Wehewehena
Hana ʻia nā uea hui Fe-Cr-Al i nā hui hao chromium alumini kumu e loaʻa ana nā mea liʻiliʻi o nā mea reactive e like me yttrium a me zirconium a hana ʻia e ka hoʻoheheʻe ʻana, ka ʻōwili kila, ka forging, annealing, drawing, surface treatment, resistance control test, etc.

ʻO ka nui o ka alumini, i hui pū ʻia me ka nui o ka chromium e hiki ai i ka mahana scaling ke piʻi i 1425ºC (2600ºF);

Ua hoʻohālikelike ʻia ke uea Fe-Cr-Al e kahi mīkini hoʻoluʻu wikiwiki kiʻekiʻe kahi e hoʻokele ʻia ai ka mana o ka mana e ke kamepiula, loaʻa lākou ma ke ʻano he uea a me ka lipine (ʻāpana).

Nā ʻano huahana a me ka laulā nui

Uea poepoe
Loaʻa nā nui ʻē aʻe he 0.010-12 mm (0.00039-0.472 ʻīniha) ma ke noi.

Lipine (uea pālahalaha)
Mānoanoa: 0.023-0.8 mm (0.0009-0.031 ʻīniha)
Laulā: 0.038-4 mm (0.0015-0.157 ʻīniha)
ʻO ka lakio laulā/mānoanoa max 60, ma muli o ke kinikini a me ke ahonui
Loaʻa nā nui ʻē aʻe ma ke noi.

Loaʻa i ka uea hoʻomehana uila kū'ē nā waiwai antioxidant ikaika, akā ʻo nā ʻano kinoea like ʻole i loko o nā umu e like me ka ea, kalapona, sulfur, hydrogen a me ka nitrogen, he hopena koʻikoʻi nō ia.

ʻOiai ua loaʻa i kēia mau uea hoʻomehana ka lāʻau antioxidant, ʻo ka halihali, ka wili ʻana, ke kau ʻana a me nā kaʻina hana ʻē aʻe e hōʻino i kahi ʻano a hoʻemi i kona ola lawelawe.

I mea e hoʻolōʻihi ai i ke ola lawelawe, pono nā mea kūʻai aku e hana i ka mālama mua ʻana i ka oxidation ma mua o ka hoʻohana ʻana. ʻO ke ʻano hana, ʻo ia ka hoʻomehana ʻana i nā mea hao i hoʻokomo piha ʻia i ka ea maloʻo i ka mahana (haʻahaʻa 100-200C ma mua o kona kiʻekiʻe loa me ka hoʻohana ʻana i ka mahana), mālama wela no 5 a 10 mau hola, a laila e hoʻomaʻalili mālie me ka umu.
