ʻO ka ʻeleʻele kahi ʻano maʻamau no ka mālama wela ʻana i ka metala. ʻO ke kumu, ʻo ia ka hana ʻana i kahi ʻili oxide ma luna o ka ʻili metala e hoʻokaʻawale i ka ea a hoʻokō i ka pale ʻana i ka popo. ʻO ka ʻeleʻele kahi ʻano maʻamau no ka mālama wela ʻana i ka metala. ʻO ke kumu, ʻo ia ka hana ʻana i kahi ʻili oxide ma luna o ka ʻili metala e hoʻokaʻawale i ka ea a hoʻokō i ka pale ʻana i ka popo.
2.ZINC
——ʻO ka Electro-galvanizing kahi ʻenehana hana uhi metala kuʻuna e hāʻawi ana i ke kūpaʻa kumu i ka pala i nā ʻili metala. ʻO nā pono nui ka maikaʻi o ke kūʻai ʻana a me ke kūpaʻa pili kūpono. Ma muli o kona mau waiwai lubrication maikaʻi, hoʻohana pinepine ʻia ka cadmium plating i nā huahana mokulele, aerospace, moana, a me nā huahana lekiō a me nā uila. Mālama ka papa plating i ke kila kila mai ka pale mechanical a me ke kemika, no laila ʻoi aku ka maikaʻi o kona kūpaʻa i ka pala ma mua o ka zinc plating.

——ʻO nā pono nui ka maikaʻi o ke kūʻai ʻana a me ke kūpaʻa kūpono i ka hoʻopili ʻana. Ma muli o kona mau waiwai lubrication maikaʻi, hoʻohana pinepine ʻia ka cadmium plating i nā huahana mokulele, aerospace, moana, a me nā huahana lekiō a me nā huahana uila. Mālama ka papa plating i ke kila kila mai ka pale mechanical a me ke kemika, no laila ʻoi aku ka maikaʻi o kona kūpaʻa i ka pala ma mua o ka zinc plating. Loaʻa i ka zinc wela ke kūpaʻa maikaʻi i ka pala, ka pale mōhai no nā substrates kila, ke kūpaʻa kiʻekiʻe o ka wā, a me ke kūpaʻa i ka ʻinoʻino o ka wai paʻakai. He kūpono ia no nā mea kanu kemika, nā hale hoʻomaʻemaʻe a me nā kahua hana kahakai a me waho.
