A na-akpọkwa efere ígwè nwere agba agba kpuchiri efere ígwèma ọ bụ efere ígwè e kpuchiri mbụ. Dị ka a na-aga n'ihu mmepụta usoro maka coils, agba ígwè efere nwere ike kewaa ụzọ abụọ: electro-galvanized na-ekpo ọkụ-mikpu galvanized.
N'otu oge ahụ, electro-galvanizing bụ usoro nke na-eme ka ọla-edo agba agba-"Layer zinc metal or zinc alloy" site na electroplating.
Galvanizing na-ekpo ọkụ na-ekpo ọkụ, nke a na-akpọkwa na-ekpo ọkụ na-ekpo ọkụ, bụ ịkụnye ngwaahịa ọla ndị dị mkpa na-edozi n'ime ígwè zinc a wụrụ awụ iji mee ka ọdịdị nke mkpuchi ígwè na-edozi anya. E jiri ya tụnyere electroplating, metal na-ekpo ọkụ na-ekpuchi mkpuchi dị oke; n'okpuru otu gburugburu ebe obibi, ọ nwere ogologo ndụ.
Nrụrụ nke oyi akwa galvanized na-ekpo ọkụ na-ekpo ọkụ n'elu ígwè ahụ bụ nke zinc dị ọcha. Nrụrụ nke zinc na ikuku dị ka usoro corrosion nke ígwè n'okpuru ọnọdụ ikuku. Chemical oxidation corrosion emee, electrochemical corrosion na-apụta n'elu zinc, na ihe nkiri mmiri na-apụta. N'ebe ikuku na-anọpụ iche ma ọ bụ na-esighị ike, ngwaahịa corrosion nke akwa akwa galvanized na-emepụta bụ ogige ndị na-adịghị edozi (zinc hydroxide, zinc oxide, na zinc carbonate). A ga-ekewa ngwaahịa ndị a site na ntinye ego ma mepụta akwa oyi akwa dị mma.
N'ozuzu, ọ nwere ike iru a ọkpụrụkpụ nke 8μm". Ụdị ihe nkiri a nwere ụfọdụ ọkpụrụkpụ, ma ọ bụghị nanị soluble na mmiri, na-enwe ike adhesion. Ya mere, ọ nwere ike igwu ihe mgbochi n'etiti ikuku na galvanized mpempe akwụkwọ. Gbochie mmebi ọzọ. A na-emebi akwa galvanized n'oge a na-arụzi ya, na akụkụ nke elu igwe na-ekpuchi ikuku.
N'oge a, zinc na ígwè na-etolite obere batrị. Ike nke zinc dị obere karịa nke ígwè. Dị ka anode, zinc nwere mmetụta pụrụ iche na-edozi anode n'elu efere ígwè iji zere mmebi nke efere ígwè.
Ibe mkpuchi agba bụ ụdị mkpuchi mmiri mmiri, nke a na-etinye n'elu igwe dị ọcha site na ahịhịa ma ọ bụ ihe mkpuchi. Mgbe ikpo ọkụ na ọgwụgwọ, enwere ike nweta ihe nkiri agba nke nwere otu ọkpụrụkpụ.
