ʻO ka ʻokoʻa ma waena o ke keleawe a me ke keleawe

Ua kapa ʻia ka keleawe no kona kala uliuli, a ua kapa ʻia ke keleawe no kona kala melemele.No laila, hiki ke hoʻokaʻawale ʻia ke kala.I mea e hoʻokaʻawale loa ʻia, koi ʻia ka loiloi metallographic.

ʻO ka ʻōmaʻomaʻo ʻeleʻele āu i ʻōlelo ai ʻo ia ke kala o ka ʻōpala, ʻaʻole ke kala maoli o ke keleawe.

ʻO kēia ka mea i hōʻike ʻia i kekahi ʻike kumu o nā alloy keleawe:

huila keleawe

Hoʻokumu ʻia nā ʻāpana keleawe ma ka hoʻohui ʻana i kekahi mau mea hoʻohui (e like me ka zinc, tin, aluminika, beryllium, manganese, silicon, nickel, phosphorus, etc.) i ke keleawe maʻemaʻe.Loaʻa i nā ʻāpana keleawe ka conductivity uila maikaʻi, ka conductivity thermal a me ke kūpaʻa corrosion, a me ka ikaika kiʻekiʻe a me ke kūpaʻa ʻana.

Ma muli o ka haku mele, ua māhele ʻia nā ʻāpana keleawe i ke keleawe a me ke keleawe.

1. ʻO ke keleawe he keleawe keleawe me ka zinc e like me ka mea hoʻohui nui.Wahi a ka haku mele, ua māhele ʻia ke keleawe i ke keleawe maʻamau a me ke keleawe kūikawā.

(1) Ke keleawe maʻamau ʻO ke keleawe maʻamau he keleawe-zinc binary alloy.Ma muli o kāna plasticity maikaʻi, kūpono ia no ka hana ʻana i nā pā, nā kī, nā uea, nā paipu a me nā ʻāpana hohonu hohonu, e like me nā paipu condenser, nā paipu hoʻomaha a me nā ʻāpana mechanical a me nā uila.Hiki ke hoʻolei ʻia ke keleawe me ka awelika keleawe o 62% a me 59% a kapa ʻia ʻo ia he keleawe hoʻolei.

(2) Ke keleawe kūikawā No ka loaʻaʻana o ka ikaika kiʻekiʻe, ke kū'ēʻana i ka corrosion a me ka hana hoʻolei maikaʻi, ua hoʻohuiʻia ka aluminika, silicon, manganese, lead, tin a me nā mea'ē aʻe i ka copper-zinc alloy e hana i ke keleawe kūikawā.E like me ke keleawe alakaʻi, keleawe keleawe, keleawe aluminika, keleawe silika, keleawe manganese, etc.

He maikaʻi loa ka ʻokiʻoki ʻana o ke keleawe a me ke kūpaʻa maikaʻi ʻana, a hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana wati, a hoʻolei ʻia e hana i nā lāʻau a me nā lāʻau.

ʻO ke keleawe keleawe maikaʻi ka pale ʻana i ka corrosion a hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana moku moana.

Hiki i ka alumini i loko o ke keleawe alumini ke hoʻomaikaʻi i ka ikaika a me ka paʻakikī o ke keleawe a hoʻomaikaʻi i kona kūpaʻa corrosion i ka lewa.Hoʻohana ʻia ke keleawe alumini no ka hana ʻana i nā ʻāpana pale-corrosion.

Hiki ke hoʻomaikaʻi i ke keleawe keleawe i loko o ka silikoni i nā waiwai mechanical, ke kūpaʻa a me ke kūpaʻa corrosion o ke keleawe.Hoʻohana nui ʻia ke keleawe silika e hana i nā ʻāpana kai a me nā ʻāpana mīkini.

ʻO Bronze ka mea mua e pili ana i ke keleawe-tin alloy, akā ua hoʻohana ʻia ka ʻoihana e kapa i nā ʻāpana keleawe i loaʻa i ka aluminika, silikoni, ke kēpau, beryllium, manganese, a me nā mea ʻē aʻe hoʻi he keleawe, no laila ke komo maoli ke keleawe i ke keleawe keleawe, ke keleawe alumini, ke keleawe alumini, ke keleawe beryllium, keleawe silika , ke keleawe alakaʻi, a pēlā aku. Ua māhele ʻia ʻo Bronze i ʻelua mau ʻāpana: ke keleawe paʻi-hana a me ke keleawe hoʻolei.

(1) Kele keleawe keleawe me ke kini me ka mea hoʻohui nui i kapa ʻia ʻo tin keleawe.ʻO ka hapa nui o ke keleawe keleawe i hoʻohana ʻia i ka ʻoihana he ʻona ma waena o 3% a me 14%.ʻO ke keleawe keleawe me ka nui o ka tin ma lalo o 5% kūpono no ka hana anu;ʻO ke keleawe keleawe me kahi kiko o 5% a 7% kūpono no ka hana wela;ʻO ke keleawe keleawe me ka nui o ka nui ma mua o 10% kūpono no ka hoʻolei ʻana.Hoʻohana nui ʻia ke keleawe keleawe i ka hana moku, ʻoihana kemika, mīkini, mea hana a me nā ʻoihana ʻē aʻe.Hoʻohana nui ʻia ia e hana i nā ʻāpana pale ʻaʻahu e like me nā bearings a me nā bushings, nā mea elastic e like me nā pūnāwai, a me nā ʻāpana anti-corrosion a me nā anti-magnetic.

(2) Aluminum keleawe keleawe me ka alumini e like me ka mea hoʻohui nui i kapa ʻia he keleawe alumini.ʻOi aku ka kiʻekiʻe o nā mea mechanical o ke keleawe alumini ma mua o ke keleawe a me ke keleawe keleawe.ʻO ka ʻike alumini o ke keleawe alumini pono ma waena o 5% a me 12%, a ʻo ke keleawe alumini me ka ʻike alumini o 5% a hiki i 7% ʻoi aku ka maikaʻi o ka plasticity a kūpono no ka hana anu.Ke ʻoi aku ka nui o ka ʻike alumini ma mua o 7% a i 8%, piʻi ka ikaika, akā e emi nui ka plasticity, no laila e hoʻohana nui ʻia i ke kūlana as-cast a ma hope o ka hana wela.ʻOi aku ka kiʻekiʻe o ke kūpaʻa abrasion a me ka corrosion o ke keleawe alumini i ka lewa, ka wai kai, ka wai kalapona kalapona a me ka nui o nā waikawa organik ma mua o ke keleawe a me ke keleawe keleawe.Hiki i ke keleawe alumini ke hana i nā mea hana, nā ʻūhā, nā ʻōpala ilo a me nā ʻāpana kūʻokoʻa ikaika kiʻekiʻe a me nā mea elastic me ke kūpaʻa kiʻekiʻe.

(3) Beryllium bronze ʻO ke keleawe keleawe me ka beryllium e like me ka mea kumu i kapa ʻia he beryllium bronze.ʻO ka helu beryllium o ka beryllium keleawe he 1.7% a 2.5%.Loaʻa i ka Beryllium bronze ka palena elastic a me ka palena luhi, ke kūpaʻa maikaʻi a me ka pale ʻana i ka corrosion, ka conductivity uila maikaʻi a me ka conductivity thermal, a loaʻa nō hoʻi nā pōmaikaʻi o ka non-magnetic, ʻaʻohe spark i ka hopena.Hoʻohana nui ʻia ka Beryllium bronze e hana i nā pūnāwai koʻikoʻi no nā mea kani pololei, nā kīʻaha uaki, nā bearings a me nā bushings e hana ana ma lalo o ke kiʻekiʻe kiʻekiʻe a me ke kaomi kiʻekiʻe, a me nā electrodes mīkini welding, nā mea pahū-hōʻoia, nā panana moana a me nā ʻāpana koʻikoʻi.
