He aha nā ʻāpana metala Sintered:
Hana ʻia nā ʻāpana metala i hoʻohana ʻia me ka aʻenehana metala pauda kapa ʻia ʻo sintering. Ma kēia ʻano, hoʻopili ʻia ka pauda metala i kahi ʻano pololei, a laila hoʻohana ʻia ka wela e hoʻopili i nā ʻāpana metala i loko o ka mea i hana ʻia, e hiki ai ke mālama i kona ʻano hou.Hoʻopaʻa ʻanahiki ke hoʻohana ʻia e hana i nā ʻano ʻāpana metala ākea a kūpono me nā metala like ʻole a me nā ala.
JIEHUANGHe poʻe loea ʻo Sintered Metals i nā kaʻina hana sintering e hoʻohuli i nā metala pauka i mau huahana metala paʻa a hilinaʻi. E aʻo hou e pili ana i ke kaʻina hana sintering metala a pehea e hiki ai ke kōkua i kāu noi ma ka heluhelu ʻana.
He aha ke kaʻina hana sintering:
Sintering kaʻina mea e hoomakaukau i ka hao oka pauka, flux, wahie a me nā mea pani e like me nā koi o ka blast smelting, e like me kekahi mahele o ka batching, hui pu ana, me ka wai lubrication. ʻO ka hoʻoponopono hou ʻana, ka hoʻoheheʻe ʻana, me ke kōkua o ka peʻahi, no laila ma lalo o ka hana o kahi wela kiʻekiʻe, e hoʻoheheʻe a hoʻoheheʻe ʻia ka ʻili o ka pauka hao a hoʻoheheʻe ʻia, e hoʻohua ai i kahi wai wai, a me nā mea hoʻoheheʻe hope loa.
ʻO ke kaʻina hana sintering kumu
kaomi pauda → ka hoʻouka ʻana (hoʻomākaukau ma mua o ka hoʻouka ʻana a me ka sintering) → sintering (hoʻomaʻamaʻa mua, mālama i ka wela a me ka hoʻoluʻu) → puka i waho → kino sintered
He aha nā pōmaikaʻi o nā ʻāpana metala Sintered?
●Through sintering, kiʻekiʻe kiʻekiʻe sinter me ka paʻa chemical haku mele 'ana, like me ka nui o ka nui, maikaʻi reducibility a me kiʻekiʻe metallurgical hana hiki ke hoʻolako 'ia no ka blast furnace, ka mea e hana i nā kūlana maikaʻi no kiʻekiʻe kiʻekiʻe, kiʻekiʻe hua, haʻahaʻa hoʻohana a me ka lōʻihi ola.
● Hiki ke wehe i nā mea haumia ʻino e like me ka sulfur, zinc, etc.;
● ʻO ka ʻōpala ʻoihana, e like me ka lepo blast furnace, ke kila i ʻōwili ʻia, sulfuric acid slag, steel slag, etc.;
● Hiki ke hoʻihoʻi hou ʻia nā metala non-ferrous a me nā metala honua kakaʻikahi.

Noi o na Huahana Metala Sintered
Nā huahana metala sinteredhoʻohana nui ʻia ma waena o nā ʻoihana he nui ma muli o kā lākou mau waiwai kūʻokoʻa e like me ka ikaika kiʻekiʻe, ke kūpaʻa ʻaʻahu, a me nā ʻae ʻana o ka dimensional. Ma lalo iho nei kekahi mau noi nui o nā huahana metala sintered:
1. ʻOihana Kaʻa
Pono nā metala sintered i ka ʻoihana kaʻa no ka hana ʻanaʻāpana ʻenekini,ʻōnaehana hoʻoili, aʻōnaehana kaʻa. Nā huahana likenā pahu pahu,nā kāʻei,nā bearings, anā palekipōmaikaʻi mai ka ikaika kiʻekiʻe o nā metala i hoʻopaʻa ʻia, ke kūpaʻa ʻana, a me ka hiki ke hana ma lalo o ka friction kiʻekiʻe a me nā kūlana wela.
2. Aerospace Industry
Hoʻohana ka ʻoihana aerospace i nā huahana metala sintered e like menā mea hoʻolālāaʻāpana ʻenekini. Sinterednā huila titaniumanickel-based superalloysua koho ʻia no ko lākou ikaika-a-kaumaha ratio, corrosion resistance, a me ke kiʻekiʻe-mehana hiki ke kūpono no ka hoʻohana ʻana i nā mokulele a me nā ʻenekini jet.
3. ʻOihana Lapaʻau
He kuleana koʻikoʻi nā huahana metala Sintered i ka ʻoihana lapaʻau, ʻoi aku hoʻi maimplants a me ka prostheticsamea hana oki. Nā mea liketitanium sinteredakila kohu ʻolemakemake ʻia no ko lākou biocompatibility, ikaika, a me ka lōʻihi, e kūpono ana iā lākou no nā implants orthopedic a me nā noi niho.
4. Mekini Hana Hana
I nā mīkini ʻenehana, hoʻohana ʻia nā metala sintered no ka hana ʻananā bearings,nā lāʻau, nā kāʻei, asprockets. Nā mea likekeleawe kiʻi ʻiaahaohāʻawi i nā waiwai lubricating maikaʻi loa a me ke kūpaʻa ʻaʻahu kiʻekiʻe, e hōʻemi ana i nā pono mālama a hoʻonui i ke ola o nā mea.
5. Mea Hoʻohana Electronics
Hoʻohana nui ʻia nā metala Sintered i nā mea uila uila no ka hana ʻanapumehana,nā moto liʻiliʻi,nā mea hoʻokani, ahoʻololi i nā ʻāpana.Copper sinteredaaluminikahōʻoia i ka hoʻokele wela kūpono a me ka hana hilinaʻi i nā mea uila.
6. ʻOihana ʻaila a me ke kinoea
Loaʻa i ka ʻoihana aila a me ke kinoea nā huahana metala sintered e like meʻāpana kānanaaʻāpana valve. Hoʻolālā ʻia kēia mau huahana e kū i ke kaomi kiʻekiʻe a me nā kūlana wela, me nā mea e hāʻawi ana i ka ikaika kiʻekiʻe a me ke kūpaʻa corrosion.
7. ʻOihana Uila
I ka ʻoihana uila, hoʻohana ʻia nā metala sintered nopili,terminals, anā ʻāpana magnetic.Kālā Sintered,keleawe, a ʻoi aku ka maikaʻi o nā mea magnetic palupalu no ko lākou conductivity maikaʻi loa, ke kūpaʻa ʻaʻahu, a me nā waiwai magnetic.
8. Mea Paahana a Make
Hoʻohana ka mea hana a me ka ʻoihana make i nā metala sintered nomea ʻoki ʻoki,nā poni, amake.ʻO ka tungsten carbide i hoʻopaʻa ʻiaʻike ʻia no kona ʻano paʻakikī loa a me ke kūʻē ʻana i ka lole, e kūpono ana ia no nā wahi kiʻekiʻe a me nā lole kiʻekiʻe.
9. Nā mea nani a me nā ʻano
ʻO nā metala i hoʻopaʻa ʻia, e like mekila kohu ʻole,titanium, ametala makamae, kaulana i nā mea nani a me ke ʻano no ka hana ʻanamea kāhikoaʻāpana kiaʻima muli o ko lākou hoʻopiʻi nani a me ka lōʻihi.
10. Na lako hale
Loaʻa nā ʻāpana metala i hoʻopaʻa ʻia i loko o nā mea hana hale like ʻole, e like menā compressorsi loko o nā pahu hau a me nā ea, a menā lauanā kāʻeii nā mea hoʻohui a me nā mea hui. Loaʻa kēia mau ʻāpana i ka ikaika, ka lōʻihi, a me ke kūpaʻa ʻana o nā metala sintered.
