ʻO ke ala hao hao ʻeleʻele hana ʻia

He kila lōʻihi me ke ʻano ʻano ʻano ʻāpana. Hiki ke hoʻokaʻawale ʻia ke kila hoʻoheheʻe wela wela i ke kila a me ke kila a me ka hao e like me ke kaʻina hana galvanizing. ʻO ia ke kila ma hope o ka hoʻopau ʻana. Hoʻokomo ʻia nā ʻāpana i ka zinc i hoʻoheheʻe ʻia ma kahi o 440 ~ 460 ℃ e hoʻopili i ka ʻili o nā ʻāpana kila i ka papa zinc, a laila e hoʻokō ai i ke kumu o ka anti-corrosion. Ma waena o nā ʻano hana uhi no ka pale ʻana i nā substrate kila, ʻo ka hot-dip galvanizing kahi mea maikaʻi loa. ʻO ia ka manawa o ka zinc i loko o kahi wai, a ma hope o nā hana kino a me nā hana kemika, ʻaʻole i uhi wale ʻia ke kila me kahi papa zinc maʻemaʻe ʻoi aku ka mānoanoa, akā ua hoʻokumu ʻia kahi ʻāpana zinc-hao. ʻAʻole loaʻa i kēia ʻano plating nā hiʻohiʻona pale corrosion o ka electro-galvanization, akā loaʻa pū kekahi i ka zinc-iron alloy layer. Loaʻa iā ia ke kūpaʻa corrosion ikaika ʻaʻole e like me ka electro-galvanizing. No laila, kūpono loa kēia ʻano plating no nā ʻano waikawa ikaika, noe alkali a me nā wahi corrosive ikaika.
