ʻO ka pauka metallurgyHe ʻepekema a me ka ʻenehana e aʻo a hana i nā pauka metala like ʻole a hoʻohana i nā pauka ma ke ʻano he mea maka no ka hoʻomākaukau ʻana i nā mea metala a me nā huahana ma ke kaomi ʻana, sintering a me ka pono o ka hana ma hope. He ʻano hana nui ia me ka ʻoki liʻiliʻi a ʻaʻole ʻole, hiki ke hana i nā ʻāpana i kūkulu ʻia me nā ʻano paʻakikī a me ka ikaika hoʻolālā kiʻekiʻe ʻoiai e hōʻemi ana i nā kumukūʻai. ʻO ia ke ala nui no ka hana nui o ka lawe ʻana i nā ʻāpana lubricating ponoʻī ma ke kumu kūʻai haʻahaʻa.
Nā pōmaikaʻi o ke kaʻina hana metallurgy pauda
Pōmaikaʻi: 1. ʻO ka hapa nui o nā metala refractory a me kā lākou pūhui, nā mea hoʻoheheʻe ʻokiʻoki i hoʻoikaika ʻia, nā mea porous, nā mea seramika a me nā carbide cemented hiki ke hana wale ʻia e nā ʻano metallurgy pauka.
2. No ka mea hiki ke paʻi ʻia ke ʻano o ka pauka metallurgy i ka nui hope o ka blank me ka ʻole a i ʻole ka liʻiliʻi o ka pono no ka hana ʻana i ka mīkini ma hope, hiki iā ia ke mālama nui i ka nui o ka metala a hoʻemi i ke kumukūʻai o ka huahana. I ka hana ʻana i nā huahana me ka pauka metallurgy, ʻo ka nalowale o ka metala he 1-5% wale nō. Ke hana ʻia e nā ʻano hoʻolei maʻamau, hiki i ka nalowale o ka metala ke hiki i 80%.
3. Mai ka pauda metallurgy kaʻina hana ole hehee ai i ka mea i loko o ka mea hana kaʻina hana, ka mea,ʻaʻole makaʻu i ka hui 'ana i nā mea haumia, a me ka sintering ua lawe 'ia i loko o ka vacuum a me ka ho'ēmi ea,ʻaʻole makaʻu i ka oxidation, aʻaʻole e hana i kekahi haumia i ka mea, no laila, e hiki ke loaa kiʻekiʻe maemae. s mea.
4. Hiki i ka pauka metala ke hōʻoia i ka pololei a me ka like o ka lākiō haku mea.
5. He kūpono ka pauka metallurgy no ka hana ʻana i nā huahana me ke ʻano like a me ka helu nui o nā huahana, ʻoi aku ka nui o nā mīkini a me nā huahana kiʻekiʻe. ʻO ka hana ʻana me ka pauka metallurgy hiki ke hōʻemi nui i nā kumukūʻai hana.
Nā hemahema okaʻina hana hao pauda
1. E noʻonoʻo i ka nui o ka ʻāpana ke loaʻa ʻole ka nui o ka hui
2. ʻOi aku ka kiʻekiʻe o ka uku mold ma mua o ka hoʻoheheʻe ʻana
Kuhikuhi hoʻomohala oka pauda metallurgy mea a me nā huahana
1. E hoʻomohala ʻia nā mea hoʻoheheʻe hao i loko o nā huahana kikoʻī nui a me nā ʻāpana kūkulu kiʻekiʻe.
2. Ka hana ʻana i nā ʻāpana hana kiʻekiʻe me ka microstructure like ʻole, paʻakikī ke hana a paʻa loa.
3. E hoʻohana i ke kaʻina hana densification i hoʻonui ʻia no ka hana ʻana i nā huila kūikawā o nā ʻano hui ʻaila maʻamau.
4. Ka hana ʻana i nā mea heterogeneous, amorphous, microcrystalline a i ʻole metastable alloys.
5. ʻO ka mīkini ʻana i nā ʻano like ʻole a i ʻole nā hui o nā ʻāpana alloy.
ʻO ka hoʻoheheʻe ʻana he hana ia e hoʻoheʻe ʻia ai ka metala i loko o kahi wai e kū ai i kekahi mau koi a ninini ʻia i loko o kahi mole. Ma hope o ka hoʻoluʻu, hoʻopaʻa ʻana, a me ka hoʻomaʻemaʻe ʻana, loaʻa kahi hoʻolei me kahi ʻano i koho mua ʻia, ka nui a me ka hana.
Nā hiʻohiʻona hoʻolei:
1. ʻO ka hoʻolei ʻana he kumu ākea o nā mea maka a me nā kumu kūʻai haʻahaʻa. Hoʻohālikelike ʻia me nā kaʻina hana hana ʻē aʻe, ʻike ʻia ka hoʻolei ʻana.
2. ʻO ka hoʻolei ʻana he metala wai, no laila hiki iā ia ke hana i nā blanks a i ʻole nā ʻāpana me nā ʻano paʻakikī, ʻoi aku ka nui a me nā kikoʻī me nā lua o loko paʻakikī.
3. ʻAʻole i kaupalena ʻia ka nui, ke kaumaha a me ka hui ʻana o nā castings, ʻoi aku ka maʻalahi
4. ʻO ke kumukūʻai hana haʻahaʻa a me ka mālama waiwai. He kiʻekiʻe ka nui o ka hoʻohana ʻana i nā mea a he ākea loa ka noi
5. ʻOi aku ka maikaʻi o nā waiwai mechanical o ka hoʻolei ʻana ma mua o ka forgings
6. Ma muli o ka nui o nā kaʻina hana hoʻoheheʻe, nui nā mea, a me ka maikaʻi ʻole o ka hoʻokele ʻana, ʻaʻole paʻa ka maikaʻi o nā pahu, a ʻoi aku ka kiʻekiʻe o nā huahana i ʻoki ʻia.
7. Nā kūlana hana maikaʻi ʻole
Nā pōmaikaʻi hoʻolei:
1. E hana i nā ʻano paʻakikī, ʻoi aku ka nui o nā ʻāpana hakahaka me nā lua o loko paʻakikī, e like me nā pahu like ʻole, nā moena, nā pā, a pēlā aku.
2. Loaʻa i ka hoʻolei ʻana i ka hiki ke hoʻololi a me ka maʻalahi. Hiki ke hoʻohana ʻia nā mea metala maʻamau i ka ʻoihana no ka hoʻolei ʻana. Hiki ke paona o ka hoolei ana mai kekahi mau grama a hiki i na haneri tona, a o ka manoanoa o ka paia ma kahi o 0.5mm a 1m.
3. ʻO nā mea maka o ka hoʻoleiʻana he mea liʻiliʻi a haʻahaʻa i ke kumukūʻai
hemahema:
1. ʻO ka hoʻolālā o nā ʻāpana he mea wehe, ʻeleʻele nā ʻōpala, a ua maʻalahi nā hemahema e like me nā lua shrinkage, shrinkage porosity, a me nā pores i hana maʻalahi i loko. No laila, ʻoi aku ka haʻahaʻa o nā waiwai mechanical o ka hoʻoheheʻe ʻana, ʻoi aku ka paʻakikī o ka hopena, ma mua o nā mea forging o ka mea like.
2. ʻAʻole paʻa ka maikaʻi o ka hoʻolei ʻana.
