Inā ʻoe i loko o ka hoʻolei metala, ʻike ʻoe i ka nui o nā hemahema e like me ka porosity, inclusions, a i ʻole nā māwae.Nā kānana ʻōhua seramika (CFF) ʻaʻole wale nā “kānana”—he mea hana koʻikoʻi lākou e hoʻomaʻemaʻe i ka metala i hoʻoheheʻe ʻia, hoʻomaikaʻi i ka pono o ka hoʻolei ʻana, a ʻoki i nā ʻōpala hana. Akā he aha ka mea i hoʻohana ʻia ai? E hoʻokaʻawale i kā lākou mau noi nui e ka ʻoihana a me ke ʻano metala, no laila hiki iā ʻoe ke ʻike pehea e kūpono ai lākou i kāu kaʻina hana.

1. Hoolei Metala Non-Ferrous: Hana i ka Aluminum, Copper, Zinc Castings Flawless

Hoʻohana nui ʻia nā metala non-ferrous (alumini, keleawe, zinc, magnesium) i nā kaʻa, uila, a me nā paipu—akā, hiki ke hoʻoheheʻe ʻia lākou i ka hoʻokomo ʻana i ka oxide a me nā ʻōpū kinoea. Hoʻoponopono ʻo Ceramic Foam Filters i kēia ma ka hoʻopaʻa ʻana i nā mea haumia ma mua o ka hiki ʻana i ka ʻōpala

Nā mea nui ma ʻaneʻi:

Aluminum Casting (ka mea nui loa no ka hoʻohana ʻole ferrous):

Hoʻopau nā kānana i nā ʻokikene Al₂O₃ a me nā ʻōpala liʻiliʻi mai ka alumini hoʻoheheʻe ʻia, e hōʻoiaʻiʻo ana i ka hoʻoheheʻe ikaika ʻana. Pono no:

Nā ʻāpana kaʻa:ʻO nā huila, nā poloka ʻenekini, nā hale hoʻouna (ʻoi aku ka liʻiliʻi o nā hemahema ʻoi aku ka lōʻihi o ke ola).

Nā ʻāpana Aerospace:ʻO nā alumini alumini māmā no nā papa mokulele (pono ka metala ultra-pure).

Nā mea kūʻai aku:ʻO nā mea kuke alumini, nā pahu kamepiula (ʻaʻohe kīnā o ka ʻili).

Ke keleawe a me ke keleawe:

Hoʻopili i nā ʻāpana sulfide a me nā ʻāpana refractory, e pale ana i ka leak i:

Nā ʻāpana paipu:ʻO nā kiwi, nā mea pono, nā paipu (koʻikoʻi no ka hana paʻa wai).

Nā ʻāpana uila:ʻO nā mea hoʻohui keleawe, nā hopena (ʻo ke keleawe maʻemaʻe e hōʻoia i ka conductivity maikaʻi).

Zinc & Magnesium Casting:

Kāohi nā kānana i ka hoʻokumu ʻana o ka oxide i ka hoʻolei ʻana i ke kaomi kiʻekiʻe (HPDC) no:

Mea uila:ʻO nā pahu kelepona Zinc alloy, nā papa pona magnesium (ʻaʻohe hemahema o nā paia lahilahi).

Lako Paahana:ʻO nā lima puka Zinc, nā ʻāpana mea hana mana magnesium (ʻano kūlike).

2. Hoolei Metala Ferrous: Hoʻopaʻa i ke kila, hao no ka hoʻohana kaumaha

ʻO nā metala ferrous (he kila, hao) e mālama i ke koʻikoʻi kiʻekiʻe—akā, hoʻoheheʻe ko lākou wela kiʻekiʻe (1500°C+) i nā kānana paʻakikī. Hoʻopili ʻia nā kānana Ceramic Foam ma aneʻi i ka slag, nā ʻāpana graphite, a me nā oxides e hōʻino ai i ka ikaika.

Nā mea nui ma ʻaneʻi:

Ke kila a me ke kila kila:

Kū'ē i nā mea hoʻoheheʻe kila wela e hana i nā ʻāpana hilinaʻi no:

ʻOihana mīkini:ʻO nā pahu kila, nā kino pahū, nā pahu pahu (ʻaʻohe māwae o loko = emi iho ka manawa hoʻomaha).

Kūkulu ʻia:ʻO nā pale hana kila kila, nā mea hoʻohui rebar (kūʻē i ka corrosion).

Lapaʻau lapaʻau:ʻO nā mea hana ʻoki kila kila, nā poho halemai (metala maʻemaʻe = hoʻohana palekana).

Ka hao hao:

Hoʻomaikaʻi i ka microstructure no:

Kaʻa:ʻO nā diski hao hina hina, nā ʻauamo hao ductile (hoʻopaʻa i ka friction a me ka torque).

Mea kaumaha:ʻO nā ʻāpana tractor hao, nā ʻauwae crusher (pono ke pale ʻana).

Paipu:ʻO nā paipu wai hao hina hina (ʻaʻohe kahe mai nā hoʻokomo).

3. Hoʻolei Kiʻekiʻe Kiʻekiʻe Kūikawā: Tackle Titanium, Refractory Alloys

No nā noi koʻikoʻi (aerospace, nuclear), kahi wela loa nā metala (1800°C+) a i ʻole reactive (titanium), hāʻule nā kānana maʻamau. ʻO nā kānana Ceramic Foam (e pili ana i ZrO₂) wale nō ka hopena.

Nā mea nui ma ʻaneʻi:

Hoʻolei ʻia ʻo Titanium Alloy:

Hiki ke hoʻoheheʻe ʻia ka Titanium me ka hapa nui o nā mea—akā, ʻaʻole paʻa nā kānana ZrO₂, hana:

Nā ʻāpana Aerospace:ʻO nā lau ʻenekini Titanium, nā mea hoʻokele mokulele (pono ka metala ultra-maʻemaʻe no ke kiʻekiʻe kiʻekiʻe).

Nā lāʻau implants:Hoʻololi ʻia ka ʻūhā Titanium, hoʻopili niho (ʻaʻohe contamination = biocompatible).

Hoolei Alloy Refractory:

Kānana i nā mea hoʻoheheʻe hao ʻole (ma muli o ka nickel, hoʻokumu ʻia ka cobalt) no:

Hana mana:ʻO nā ʻāpana huila kinoea nickel-alloy (nā lima 1000°C+ exhaust).

ʻoihana nuklea:ʻO ka pale wahie Zirconium alloy (kūʻē i ka radiation a me nā mahana kiʻekiʻe).

No ke aha e lanakila ai nā kānana Ceramic Foam i nā koho ʻē aʻe?

ʻAʻole like me ka uea mesh a i ʻole nā kānana one, CFFs:

Loaʻa i kahi ʻano porous 3D (ʻoi aku ka nui o nā haumia, ʻoi aku ka liʻiliʻi).

E kū i ka wela wela (1200–2200°C, e pili ana i ka mea).

E hana me nā metala nui a pau (alumini a titanium).

E ʻoki i ka nui o nā ʻōpala ma 30–50% (e mālama i ka manawa a me ke kālā).

E kiʻi i ka CFF kūpono no kāu hihia hoʻohana

Inā ʻoe e hoʻolei ana i nā ʻāpana kaʻa alumini, nā ʻili kila kila, a i ʻole nā titanium implants, loaʻa iā mākou nā kānana Ceramic Foam i kūpono i kāu mau pono. Hoʻokō kā mākou kānana i nā kūlana ISO/ASTM, a kōkua kā mākou hui iā ʻoe e koho i ka mea kūpono (Al₂O₃ no ka alumini, SiC no ke kila, ZrO₂ no ka titanium).

E kelepona mai iā mākou i kēia lā no kahi laʻana manuahi a me kahi ʻōlelo maʻamau. E ho'ōki i ka hakakā ʻana i nā hemahema—hoʻomaka e hana i nā ʻāpana kīnā ʻole me CFF!
