ʻO ka mea
Ke kūʻai aku ka poʻe i nā laka, hopohopo lākou no ka lōʻihi ʻole o ka laka a ʻaʻole lōʻihi ma hope o ka ʻōpala a i ʻole ka oxidation.Pili kēia pilikia i ka mea i hoʻohana ʻia a me ka mālama ʻana i ka ʻili.
Mai kahi manaʻo paʻa, ʻo ka mea maikaʻi loa he kila kila, ʻoi aku ka maikaʻi ma ke ʻano he ʻili, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka mālamalama.Kona ikaika, corrosion kū'ē, waihoʻoluʻu 'ole.Akā aia kekahi ʻano o ke kila kila, hiki ke hoʻokaʻawale ʻia i ferrite a me austenitic.Ferritic kuhiliʻole kila he magnetic, maʻamau i ʻike ʻia he kuhiliʻole hao, lōʻihi, ʻaʻole maikaʻi ke kaiapuni e ʻōpala, ʻaʻole ʻōpala wale ke kila kulika austenitic, maʻalahi loa ke ʻano o ka ʻike, me kahi magnet hiki ke ʻike ʻia.
ʻO ke keleawe kekahi o nā mea paʻa i hoʻohana nui ʻia, me nā waiwai mechanical maikaʻi, ke kūpaʻa maikaʻi ʻana i ka corrosion a me ka hana ʻana i nā waiwai, a me ka waihoʻoluʻu ʻālohilohi, ʻoi aku ka paʻa a me nā ʻāpana hoʻonaninani ʻē aʻe o ke keleawe forging, ʻili maʻemaʻe, ʻano maikaʻi, ʻaʻohe pores, sandholes.Hiki ke hoʻohana i ke gula 24K a i ʻole nā ʻano hana ʻili āpau e like me ke gula placer, nani, kiʻekiʻe a maʻalahi hoʻi, ʻo ka hale e hāʻawi i ka poʻe i nā kala he nui.
ʻOi aku ka maikaʻi o ka mea hao Zinc, kona ikaika a me ka pale ʻana i ka ʻōpala, akā maʻalahi kona pono e hana i nā ʻano paʻakikī o nā ʻāpana, ʻoi aku ka paʻakikī.ʻO ka laka i ʻike ʻia e ka mākeke paʻakikī, he zinc alloy paha i hana nui ʻia, makemake ka mea kūʻai aku e hoʻokaʻawale pono.
ʻO ka hao a me ke kila, ikaika maikaʻi, haʻahaʻa ke kumu kūʻai, akā maʻalahi i ka ʻōpala, hoʻohana maʻamau e like me ka laka i loko o nā mea kūkulu hale, ʻaʻole like me nā ʻāpana hoʻonaninani waho.
ʻO nā alumini alumini a i ʻole nā alumini alumini, nā alumini alumini maʻamau (ma waho aʻe o ka aerospace) palupalu a māmā, me ka ikaika haʻahaʻa akā maʻalahi ke hana.
