ʻO ka Galvanizing e pili ana i ka ʻenehana lapaʻau ili o ka hoʻopaʻa ʻana i kahi papa o ka zinc ma ka ʻili o ka metala, ka hao a i ʻole nā mea ʻē aʻe no ke kumu o ka nani a me ka pale ʻana.
Hiki ke hoʻoheheʻe ʻia ʻo Zinc i nā waikawa a me ka alkali, no laila ua kapa ʻia ʻo ia ka metala amphoteric. Hoʻololi liʻiliʻi ʻo Zinc i ka ea maloʻo. Ma ka ea maʻemaʻe, e hana ka ʻili zinc i kahi film zinc carbonate kumu. No ka matrix kila, pili ka zinc coating i ka anodic coating, i hoʻohana nui ʻia e pale i ka corrosion o ke kila. ʻO kāna hana palekana he pilina maikaʻi loa me ka mānoanoa o ka uhi.
ʻO ke kumu o ka hoʻomaʻamaʻa wikiwiki ʻana i ka ʻili o ka hao a me nā huahana kila e hana i kahi ʻāpana pale kiʻi ʻoniʻoni oxide. ʻElua mau ʻano hana maʻamau o ka ʻeleʻele: ʻeleʻele hoʻomehana alkaline kuʻuna a me ka ʻeleʻele hope i ka lumi wela. hydroxide a me ka sodium nitrite.ʻO ka mahana e pono ai no ka blackening he ākea, mai kahi o 135 degere Celsius a 155 degere Celsius, a loaʻa iā ʻoe kahi ili maikaʻi, akā pono kekahi manawa. Ma ka hana pono, pono e uku ʻia i ka maikaʻi o ka ʻeleʻele a me ka ʻaila ma mua o ka blackening o ka mea hana, a me ka passivation aila immersion ma hope o ka blackening. oxidation aiʻole acid oxidation.ʻO ke kaʻina hana o ka hana ʻana i kahi kiʻiʻoniʻoni oxide ma ka ʻili metala e pale ai i ka corrosion ua kapa ʻia ʻo "bluing". ʻO ke kiʻi oxide i hana ʻia ma ka ʻili o ka metala ʻeleʻele ma hope o ka mālama ʻana i ka "bluing", ʻo ka ʻaoʻao o waho ka nui o ka ferric oxide a ʻo ka papa o loko he ferrous oxide.
Hoʻohana maʻamau ʻia nā bolts kiʻekiʻe i nā hui koʻikoʻi, e pili ana i ka ʻoi aʻe o ka ʻāʻī a me ka ʻā. ʻO kaʻeleʻeleʻeleʻele i hanaʻia e ka hoʻomaʻamaʻa houʻana i nā bolts ikaika kiʻekiʻe he kiʻiʻoniʻoni oxidation paʻa.
