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 ka Zinc i nā waikawa a me ka alkali, no laila ua kapa ʻia ʻo ia me ka amphoteric metal. Hoʻololi liʻiliʻi ka Zinc i ka ea maloʻo. ʻAʻole maikaʻi ke kūpaʻa, ʻoi aku ka nui o ka wela a me ka haʻahaʻa kiʻekiʻe e loaʻa ana i ka lewa waikawa organik, maʻalahi ka hoʻopili ʻana o ka zinc. 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 kumumanaʻo, ʻo ia ka wikiwiki o ka oxidize i ka ʻili o ka hao a me nā huahana kila e hana i kahi ʻāpana pale kiʻi ʻoniʻoni ʻoniʻoni. ʻAʻole maikaʻi ke kila kalapona haʻahaʻa. ʻOi aku ka maikaʻi o ka ʻeleʻele ʻana i ke kila A3 me ka alkali. Ua māhele ʻia ka ʻeleʻele ʻeleʻele, loaʻa hou ka ʻeleʻele a ʻelua ʻeleʻele ʻokoʻa. laula, mai ma kahi o 135 degere Celsius a hiki i 155 degere Celsius, a loaʻa iā ʻoe kahi ʻili maikaʻi, akā lawe ia i kekahi manawa. Ma ka hana pono, pono e uku ʻia i ka maikaʻi o ka rust a me ka wehe ʻana i ka aila ma mua o ka blackening o ka workpiece, a me ka ʻO ka hoʻokomoʻana i kaʻaila passivation ma hope o kaʻeleʻele.ʻO ka maikaʻi o kaʻeleʻele pinepine e like me kēia mau kaʻina hana. ʻO ka wai lāʻau lapaʻau "bluing" metal e hoʻohana i ka alkaline oxidation a iʻole ka acid oxidation. ʻO ke kaʻina hana o ka hanaʻana i kahi kiʻiʻoniʻoni ma luna o kaʻili metala e pale ai i ka corrosion ua kapaʻiaʻo "bluing". ʻO ke kiʻiʻoniʻoni oxide i hoʻokumu ʻia ma ka ʻili o ka metala ʻeleʻele ma hope o ka mālama ʻana i ka "bluing", ʻo ka papa waho ka nui o ka ferric oxide a ʻo ka ʻāpana o loko he ferrous oxide.
Hoʻohana mau ʻia nā kīʻaha kiʻekiʻe i nā hui koʻikoʻi, e pili ana i ka ʻoi aʻe o ka haʻalulu a me ka ʻā. galvanizing bolts.Hydrogen embrittlement keʻano maʻamau e ka lohi lohi.ʻO kēia ka mea e ho'ēmi ai i ka ikaika o nā bolts ikaika kiʻekiʻe. ʻaʻole pili me nā mea ʻino.
