Pehea e ʻike ai i ke ʻano ohuila keleawe?
ʻO ke keleawe keʻokeʻo, ke keleawe, ke keleawe ʻulaʻula (ʻike ʻia hoʻi ʻo "ʻulaʻula keleawe"), a me ke keleawe (uliuli-hina a hina-melemele) ʻokoʻa ma ke kala.I waena o lākou, he maʻalahi loa ke ʻike ʻana i ke keleawe keʻokeʻo a me ke keleawe;ʻO ke keleawe ʻulaʻula he keleawe maʻemaʻe (nā haumia <1%) a me ke keleawe (ʻo nā ʻāpana ʻē aʻe ma kahi o 5%), he mea paʻakikī ke ʻike.Ke unoxidized, ʻoi aku ka mālamalama o ke kala o ke keleawe ʻulaʻula ma mua o ke keleawe, a ʻo ke keleawe he cyan a i ʻole melemele ʻeleʻele;ma hope o ka oxidation, lilo ke keleawe ʻulaʻula i ʻeleʻele, a ʻo ke keleawe he turquoise (hoʻopilikia kino o ka wai) a i ʻole ke kokoleka.
Hoʻokaʻawale a me nā hiʻohiʻona o ke keleawe a me ke keleawe:
(1) Ke keleawe maʻemaʻe: Ua kapa pinepine ʻia ke keleawe ʻulaʻula.He maikaʻi ka uila conductivity, thermal conductivity a me ka corrosion kū'ē.Hōʻike ʻia ke keleawe maʻemaʻe e ka leka + T}} (ke keleawe), e like me Tl, T2, T3, a me nā mea ʻē aʻe. hōʻike ʻia e TU (keleawe manuahi), e like me TU1, TU2, etc.
(2) Brass: ʻO ke keleawe keleawe me ka zinc e like me ka mea hoʻohui nui i kapa ʻia he keleawe.Hoʻohana keleawe +H;(melemele) ʻo ia ka H80, H70, H68, etc.
(3) Bronze: I ka wā ma mua, ua kapa ʻia ke keleawe a me ka tin i ke keleawe, akā i kēia manawa ua kapa ʻia nā ʻāpana keleawe ʻē aʻe i ke keleawe.ʻO ka mea maʻamau ka keleawe keleawe, ke keleawe alumini a me ke keleawe min.Hōʻike ʻia ka keleawe e "Q" (cyan).
ʻO nā hiʻohiʻona wili o ke keleawe a me ke keleawe: ① paʻakikī e hoʻohui a maʻalahi hoʻi e hoʻololi;② maʻalahi e hana i nā māwae wela;③ maʻalahi e hana i nā pores
Hoʻohana nui ʻia ka hoʻoheheʻe ʻana o ke keleawe a me ke keleawe i ka hoʻoheheʻe ʻana i ke kinoea, ka hoʻoheheʻe ʻana i ka pale kinoea inert, ka wiliwili arc submerged, brazing a me nā ʻano hana ʻē aʻe.
He maikaʻi ka wela o ke keleawe a me ke keleawe, no laila e hoʻomaʻamaʻa mua ʻia lākou ma mua o ka wili ʻana, a pono e hoʻohana ʻia ka ikehu laina nui no ka wili.Hoʻohana ka hydrogen tungsten arc welding i ka pilina maikaʻi DC.I ka hoʻoheheʻe kinoea, hoʻohana ʻia ka lapalapa kūlohelohe a i ʻole ka lapalapa carbonization nāwaliwali no ke keleawe, a hoʻohana ʻia ka lapalapa oxidizing palupalu no ke keleawe e pale ai i ka hoʻoheheʻe ʻana o ka zinc.
