He aha nā ʻokoʻa o ka pauka metallurgy a me ka hoʻolei ʻana

ʻO ka hana ʻana i ka pauka metalakaʻina hanahe ʻepekema a me ka ʻenehana e noiʻi a hana i nā pauka metala like ʻole, a hoʻohanapauda metalae like me nā mea maka e hana i nā mea metala a me nā huahana ma o ka hoʻoheheʻe ʻana, sintering in metallurga me ka pono o ka hana ma hope.

He ʻano hana nui ia e hoʻohana liʻiliʻi a ʻaʻole ʻoki ʻoki. Hiki ke hanaʻāpana hana metalame nā ʻano paʻakikī a me ka ikaika kiʻekiʻe ma ke kumu kūʻai haʻahaʻa. He ala ia no ka hana nui o ka lawe ʻana i nā ʻāpana lubricating ponoʻī ma ke kumu kūʻai haʻahaʻa.

Maʻamauʻāpana metala paudae komo pū me: nā ʻāpana kaʻa, nā mīkini, nā bearings i hoʻopaʻa ʻia i ka aila, nā ʻāpana engine.

pololeimake hooleiNo nā metala a i ʻole nā ​​ʻāpana me nā wahi heheʻe haʻahaʻa, hiki i ka hoʻolei pololei ʻana ke hana i nā ʻāpana me nā ʻano paʻakikī ʻekolu. Akā, no nā metala refractory a me nā alloys, nā mea paʻakikī,hoʻoheheʻe ʻia ka pauda keramika, a me nā mea ʻē aʻe, ʻaʻole hiki iā lākou ke hana i kekahi mea, i hoʻoholo ʻia e ke ʻano o ka hoʻolei pololei ʻana. Eia kekahi, paʻakikī loa ka hoʻoholo ʻana i ka hoʻolei pololei ʻana no nā ʻāpana metala me ka liʻiliʻi liʻiliʻi, ka paia lahilahi a me ka nui.

Nā ʻāpana hoʻolei maʻamau: moʻo ʻāpana ʻaila, moʻo ʻāpana kaʻa, nā ʻāpana kaʻa sreies, moʻo ʻāpana lako.
