keleawe
ʻO ka hoʻohana ʻana i ke keleawe a me ke keleawe mai nā kenekulia, a ua hoʻohana ʻia i kēia lā i kekahi o nā ʻenehana hou a me nā noi ʻoiai ke hoʻohana mau ʻia nei nā noi maʻamau e like me nā mea kani, nā maka keleawe, nā mea hoʻonaninani a me nā lako paʻi a me nā puka.
He aha ke keleawe i hana ʻia?
ʻO Brass kahi huila i hana ʻia mai ka hui ʻana o ke keleawe a me ka zinc e hana i nā mea me ka nui o ka hoʻohana ʻenehana. Hāʻawi ka hui keleawe i ka metala i wahi heheʻe kūpono no nā noi he nui, me ka kūpono no ka hoʻohui ʻana me ka hoʻohana ʻana i ka ʻenehana brazing. He haʻahaʻa ka helu heheʻe o ke keleawe ma mua o ke keleawe ma kahi o 920 ~ 970 degere Celsius ma muli o ka nui o ka Zn hoʻohui. He haʻahaʻa ka helu heheʻe keleawe ma mua o ke keleawe ma muli o ka Zn i hoʻohui ʻia. Hiki ke hoʻololi ʻia nā ʻāpana keleawe i ka haku mele Zn mai ka liʻiliʻi e like me 5% (ʻoi aku ka mea i kapa ʻia ʻo Gilding Metals) a ʻoi aku ma mua o 40% e like me ka hoʻohana ʻana i nā keleawe mīkini. ʻO kahi huaʻōlelo i hoʻohana ʻole ʻia he keleawe keleawe, kahi i hoʻohana ʻia ai kekahi mau mea hoʻohui o ka tin.
He aha ka mea i hoʻohana ʻia ke keleawe?
ʻO ka hui keleawe a me ka hoʻohui ʻana o ka zinc i ke keleawe e hoʻonui i ka ikaika a hāʻawi i nā ʻano ʻano like ʻole, kahi e hana ai nā keleawe i kahi ʻano nui o nā mea. Hoʻohana ʻia lākou no ko lākou ikaika, pale ʻana i ka corrosion, hiʻohiʻona a me ke kala, a me ka maʻalahi o ka hana ʻana a me ka hui pū ʻana. ʻO nā keleawe alpha alpha hoʻokahi, aia a hiki i ka 37% Zn, he ductile a maʻalahi i ka hana anu, weld a braze. Hoʻohana maʻa mau nā keleawe ʻelua alpha-beta.
Aia ma mua o hoʻokahi haku mele keleawe?
Nui nā keleawe me nā haku mele like ʻole a me nā hiʻohiʻona i hoʻohālikelike ʻia no nā noi kikoʻī e ka pae o ka hoʻohui o ka zinc. ʻO nā pae haʻahaʻa o ka hoʻohui Zn i kapa pinepine ʻia ʻo Guilding Metal a i ʻole Red Brass. ʻOiai ʻo nā kiʻekiʻe kiʻekiʻe o Zn he mau mea hoʻohui e like me Cartridge Brass, Free Machining Brass, Naval Brass. Hoʻohui pū ʻia kēia mau keleawe hope me nā mea ʻē aʻe. Ua hoʻohana ʻia ka hoʻohui ʻana o ke alakaʻi i ke keleawe no nā makahiki he nui e kōkua i ka machinability o ka mea ma o ka hoʻoulu ʻana i nā wahi haki. I ka ʻike ʻia ʻana o ka pilikia a me nā pōʻino o ke kēpau, ua hoʻololi hou ʻia me nā mea e like me ke silicon a me ka bismuth e hoʻokō ai i nā ʻano machining like. Ua ʻike ʻia kēia mau mea he kepau haʻahaʻa a i ʻole ke keleawe manuahi ʻole.
Hiki ke hoʻohui ʻia nā mea ʻē aʻe?
ʻAe, hiki ke hoʻohui ʻia nā mea hoʻohui ʻē aʻe i ke keleawe a me ke keleawe. ʻO nā hiʻohiʻona Commons ke alakaʻi no ka mīkini-hiki e like me ka mea i ʻōlelo ʻia ma luna, akā he arsenic no ka pale ʻana i ka corrosion i ka dezincification, tin no ka ikaika a me ka corrosion.
Kala keleawe
I ka hoʻonui ʻia ʻana o ka zinc, hoʻololi ke kala. Hiki ke like ke kala me ke keleawe me ke kala ha'aha'a ha'aha'a ha'aha'a, a he gula a melemele paha ka zinc ki'eki'e.
