Kaʻina hana sintering Powder Metallurgy

ʻO ka hoʻopaʻapaʻa ʻana i ka pauka metallurgy he hana ia e hui pū ai i ka sintering a me ka mālama wela, ʻo ia hoʻi, ma hope o ka hoʻopaʻa ʻia ʻana o kekahi mea a hoʻomaʻalili wikiwiki ʻia, hana ʻia ka martensite (maʻamau maʻamau > 50%) i loko o ke ʻano metallographic, i hana ʻia ka mea hana Play a ʻoi aku ka maikaʻi o ka hana a hoʻomaikaʻi i ka hoʻokele waiwai.

ʻO nā pōmaikaʻi o ka paʻakikī sintering:

1. Hiki ke hoʻokuʻu ʻia ke kaʻina hana wela

2. E pale i ka haumia o ka aila kinai

3. Maʻalahi e huhū i ka lewa

4. E ho'ēmi i ka deformation huahana

5. Hoʻonui i ka mana nui

6. E hoʻomaikaʻi i ka hoʻokele waiwai

7. Ka hoʻohana ʻana i ka paʻakikī sinter

Hoʻohana pinepine ʻia nā mea hoʻopaʻa paʻakikī i hoʻohana ʻia no ka hana ʻana i nā ʻāpana ʻāpana a me nā ʻāpana kiʻekiʻe.I kēia manawa, hoʻohana nui ʻia ke kaʻina hana paʻakikī sinter i nā huahana paʻakikī ke kinai ma muli o ka nui a me ke ʻano.E like me nā ʻāpana ʻāpana, nā hub synchronizer, nā ʻano ʻano kūikawā a i ʻole nā ​​ʻāpana ʻāpana ʻāpana a me nā ʻāpana hana ʻē aʻe.ʻO ka hōʻuluʻulu manaʻo, ʻo ka hoʻopaʻa ʻana i ka pauka metalalurgy sinter hardening kekahi o nā ala kūpono loa e hoʻololi ai i nā kaʻina hana mālama wela me ka pauka, a ʻoi aku ka maikaʻi ma mua o kona mau hemahema.ʻO ke koho ʻana i nā mea kūpono no ka sintering a me ka paʻakikī ʻaʻole hiki ke pale wale i nā hopena maikaʻi ʻole o ka mālama ʻana i ka wela a hoʻemi i nā kumukūʻai, akā e hoʻomanaʻo ʻo nā huahana ma hope o ka sintering a me ka paʻakikī ʻana pono e hoʻomaʻamaʻa ʻia i ka manawa, maʻamau ma kahi mahana wela o 180 ° C.
