1. ELELE
-----He ala maʻamau ka ʻeleʻele no ka mālama ʻana i ka wela metala. ʻO ke kumu o ka hana ʻana i kahi kiʻiʻoniʻoni oxide ma ka ʻili metala e hoʻokaʻawale i ka ea a hoʻokō i ka pale ʻana i ka ʻōpala. ʻO ka ʻeleʻele kahi ala maʻamau no ka mālama ʻana i ka wela metala. ʻO ke kumu o ka hana ʻana i kahi kiʻiʻoniʻoni oxide ma ka ʻili metala e hoʻokaʻawale i ka ea a hoʻokō i ka pale ʻana i ka ʻōpala.
2.ZINC
——Electro-galvanizing he ʻenehana lapaʻau kuʻuna metala e hāʻawi ana i ke kūpaʻa ʻino kumu i nā ʻili metala. ʻO nā pōmaikaʻi nui he solderability maikaʻi a me ke kūpaʻa pili kūpono. Ma muli o kāna mau waiwai lubrication maikaʻi, hoʻohana pinepine ʻia ka cadmium plating i ka mokulele, aerospace, moana, a me nā lekiō a me nā huahana uila. Mālama ka papa plating i ka substrate kila mai ka pale mechanical a me ka pale kemika, no laila ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion ma mua o ka zinc plating.
