ʻO ka hoʻoheheʻe ʻia ʻana o ka pauka

ʻO nā ʻano hana Sintering o ka pauda metallurgy (hoʻoheheʻe ʻia i ka pauka)

ʻO nā ʻano hana sintering powder metallurgy ka nui o kēia mau mea:

ʻO ka pauka metallurgypono i nā ʻanuʻu kaʻina hana e like me ka hana pauda, ​​kaomi ʻana, sintering, a me ka hoʻoponopono hope. Ma waena o lākou, ʻo ka pauka metallurgy sintering kahi kaʻina mālama wela kiʻekiʻe e hoʻohui hou i nā compacts a i ʻole nā ​​​​kino pauka e hoʻomaikaʻi i ka ikaika a me nā waiwai ʻē aʻe. Eia nō naʻe, ma muli o ka ʻokoʻa, hoʻokaʻawale ʻia nā ʻano hana sintering powder metallurgy i nā ʻano he nui.

1. ʻO ka hoʻoheheʻe ʻana i ka wai

Inā he ʻelua a ʻoi aku paha nā ʻāpana o ka pauka paʻa, hiki ke hana ʻia ka sintering ma luna o ka helu heheʻe o kekahi ʻāpana, no laila e ʻike ʻia kahi wahi liʻiliʻi o ka wai i loko o ka pauda compact i ka wā sintering.

2. Paʻi sintering

I ka wā o ka sintering, hoʻohana ʻia ke kaomi i ke kino pauka e hāpai i kāna kaʻina hana densification. Paʻihoʻopaʻa ʻanai kekahi manawa like me ke kaomi wela, ʻo ia ke kaʻina hana e hui pū ai i ka hana ʻana a me ka sintering o nā pauka e loaʻa pololei nā huahana.

3. Hoʻoulu ʻia ka sintering

Ma ke kaʻina hana sintering, ua lawe ʻia kekahi mau hana kino a i ʻole kemika e hōʻemi nui i ka mahana o ka sintering a hoʻopōkole i ka manawa sintering, ʻoiai e hoʻomaikaʻi a hoʻomaikaʻi ʻia ka hana o ke kino sintered.

4. EDM sintering

Ke hoʻokumu ʻia ke kino pauka a kaomi ʻia, hoʻohana ʻia ka ʻenekini pololei a me ka uila pulse e hoʻohua ai i kahi arc ma waena o nā ʻāpana pauda no ka sintering; i ka wā o ka sintering, hoʻopili mālie ʻia ke kaomi i ka mea hana, a ua hui pū ʻia nā kaʻina hana ʻelua o ka hoʻokumu ʻana a me ka sintering.

ʻO nā mea i hōʻike ʻia ma luna nei, ʻo ia nā ʻano hana sintering metallurgy pauda maʻamau. Ma o kēia mau hana sintering, hiki ke hoʻopau pono ʻia ke kaʻina hana sintering pauda. No ka mea, i ke kaʻina hana o ka pauka metallurgy sintering, e hoʻomau nā ʻāpana pauka i nā kaʻina kino a me nā kaʻina hana e like me ke kahe ʻana, diffusion, hoʻoheheʻe, a me ka recrystallization, no laila e hoʻonui hou ʻia ke kino pauka a hoʻopau ʻia kekahi o nā pores.

Nā kumuwaiwai hou aʻe

ʻO nā mea hana hoʻoheheʻe

Kaʻina hana hoʻoheheʻe lepo
