ʻO nā ʻāpana kaʻa kaʻa PM i hoʻopaʻa ʻia

Pono opauda metallurgy

1, ʻo ka hapa nui o nā metala refractory a me kā lākou pūhui, nā alloys wahaheʻe, nā mea porous hiki ke hana wale ʻia e nā ʻano metallurgy pauka.
2, no ka mea hiki ke kaomi ʻia ke ʻano o ka pauka metallurgy i ka nui hope o ka compact, me ka ʻole o ka pono a i ʻole ka liʻiliʻi no ka hoʻoili ʻana i ka mīkini ma hope,
No laila, hiki iā ia ke mālama nui i ka metala a hoʻemi i nā kumukūʻai huahana. Ke hoʻohana ʻia ke ʻano hana metallurgy pauka e hana i nā huahana, ʻo 1-5% wale nō ka nalowale o ka metala, a ke hoʻohana ʻia ke ʻano hoʻoheheʻe maʻamau a me ka hoʻolei ʻana, hiki i ka nalowale o ka metala ke hiki i 80%.
3, no ka mea, ʻaʻole e hoʻoheheʻe ke kaʻina hana pauka i ka mea hana, ʻaʻole makaʻu i ka hui ʻana me nā haumia i lawe ʻia e ka crucible a me ka deoxidizer, a ke hana maʻamau ʻia ka sintering i loko o ka vacuum a me ka hoʻohaʻahaʻa ʻana i ka lewa, ʻaʻole makaʻu i ka oxidation, ʻaʻole ia e hāʻawi i kahi haumia i ka mea, no laila hiki ke hana i nā mea maʻemaʻe kiʻekiʻe.
4, hiki i ke ala metallurgy pauka ke hōʻoia i ka pololei a me ka kūlike o ka lākiō haku mele.
5, kūpono ka pauka metallurgy no ka hana ʻana i ke ʻano like a me ka nui o nā huahana, ʻoi aku ka nui o ka mīkini a me nā kumukūʻai kiʻekiʻe kiʻekiʻe o nā huahana, me ka hana ʻana i ka pauka metallurgy hiki ke hōʻemi nui i nā kumukūʻai hana.
