He aha ka pauda metala?

ʻO ka hōʻiliʻili o nā ʻāpana metala ma lalo o hoʻokahi millimeter i kapa ʻia he pauda metala. ʻO kēia ka mea maka mua i hoʻohana ʻia i ka pauka metallurgy a loaʻa i ka metala hoʻokahi, alloy, a me kekahi pauka composite refractory me nā ʻano metala.

He aha nā ʻāpana metala pauda?

ʻO ke kaʻina hana ʻāpana metala ka hana metala a hoʻohana paha i ka pauka metala (a i ʻole ka pauka metala a me ka hui ʻana o ka pauka non-metal) ma ke ʻano he kumu, ma hope o ka hoʻokumu ʻana a me ka sintering MIM, ka hana ʻana i nā mea metala, nā mea hana a me nā ʻano ʻenehana huahana like ʻole. ʻO ka ʻoihana ʻāpana metala pauka maʻamau me nā mea hao a me nā mea hana pōhaku, carbide cemented, nā mea magnetic. Ma ka manaʻo haiki, ʻO ka ʻoihana ʻāpana metala pauka e pili wale ana i nā huahana metallurgy pauka, meʻāpana metallurgy pauda(heluhelu no ka hapa nui), lawe aila anā huahana hoʻoheheʻe metala.

Nā mea metala pauda

ʻAno ʻāpana metala pauda

• hiki ke hoʻomaluʻia ka nui o ka huahana, e like me nā mea porous, nā mea momona maikaʻi;
• palaoa maikaʻi, ʻano microstructure like ʻole, ʻaʻohe mea hoʻokaʻawale;
• kokoke i ka hoʻokumu ʻana, ka nui o ka hoʻohana ʻana i nā mea waiwai> 95%;
• liʻiliʻi ʻaʻole ʻoki ʻia, ʻoki ʻoki i ka hana ʻana wale nō 40 ~ 50%;
• hiki ke hoʻopaʻa ʻia ka hoʻohui ʻana o nā mea waiwai, kahi kūpono i ka hoʻomākaukau ʻana i nā mea hana;
• ka hoʻomākaukau ʻana i nā metala refractory, nā mea seramika a me nā mea nuklea.

Māhele metala pauda kahe kaʻina hana kumu

1, Ka pulupulu

ʻO ka pulupulu ka hana ʻana i nā mea maka i pauka. ʻO nā ʻano hana pulverizing i hoʻohana pinepine ʻia ʻo ke ʻano hoʻohaʻahaʻa oxide a me ke ʻano mechanical.

2, Huihui

ʻO ka hui ʻana ke ʻano o ka hana ʻana i ka pauka billet ma ka hoʻohui ʻana i nā ʻano pauka i makemake ʻia i kekahi ʻāpana a homogenizing ia. Māhele ʻia i maloʻo, semi-maloʻo a pulu ʻekolu, kēlā me kēia no nā koi like ʻole.

3, Hookumu ana

ʻO ka hana ʻana ʻo ia ke kaʻina hana o ka blank me kekahi ʻano, ka nui a me ka nui ma o ka hoʻouka ʻana i ka mea i hui pū ʻia i loko o ka pahu kaomi ma lalo o ke kaomi kaumaha. Hoʻokaʻawale ʻia ke ʻano molding i loko o ke kaomi kaomi ʻana a ʻaʻohe kaomi kaomi. ʻO ka hoʻoheheʻe kaomi ka mea i hoʻohana nui ʻia i ka hana ʻana.

4, Hoopanee

5. Mahope o ka hana ana

  Ma hope o ka hoʻomaʻamaʻa sintering, e like me nā koi ʻāpana metala ʻokoʻa, e lawe i nā ʻano like ʻole. E like me ka hoʻopau ʻana, ka luʻu ʻana, ka mīkini, ka mālama wela a me ka electroplating. Eia kekahi, i nā makahiki i hala iho nei, ua hoʻohana ʻia kekahi mau kaʻina hana hou e like me ka rolling a me ka forging i ka sintering o nā mea metallurgy pauka a loaʻa nā hopena maikaʻi aʻe.

ʻO ka pauka sintering he kaʻina hana koʻikoʻi ma ke kaʻina hana metallurgy pauda. Ma hope o ka hoʻokumu ʻana, hoʻopaʻa ʻia ka billet no ka loaʻa ʻana o nā waiwai kino a me nā mechanical. Hoʻokaʻawale ʻia ʻo Sintering i ka metallurgy i ka sintering unit a me ka multi-system sintering. Ma waho aʻe o ka sintering maʻamau, loaʻa ka sintering loose, ka hoʻomoʻa ʻana, ka paʻi wela a me nā kaʻina hana sintering kūikawā.
