Kev siv cov zinc coatings los tiv thaiv hauv qab steel substrates los ntawm corrosion tau ua pov thawj zoo nyob rau hauv huab cua huab cua. Cov txheej txheem tiv thaiv corrosion feem ntau suav nrog: (1) Ib txheej nyias, ntom ntom zinc oxide cov ntaub ntawv ntawm zinc txheej txheej. Raws li cov txheej txheem no yog insoluble nyob rau hauv dej, nws muab kev tiv thaiv rau lub hauv paus zinc hlau. Txawm li cas los xij, thaum txheej oxide nce mus txog kwv yees li 300 nanometers hauv thickness, nws ua rau detachment. Thaum zinc oxide reacts nrog atmospheric Cheebtsam los tsim insoluble zinc ntsev, lub corrosion kuj yuav ua tau zoo dua.
(2) Zinc txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej steel, nws tuaj yeem zam cov hlau substrate tiv tauj nrog cov tshuaj tiv thaiv corrosion, tiv thaiv cov hlau substrate los ntawm corrosion.
(3) Thaum cov dej me me los yog cov hlau raug pom nyob rau ntawm cov hlau matrix, zinc txheej tuaj yeem tsim cov hlau -zinc ob peb microcell nyob rau hauv cov xwm txheej ntawm cov electrolyte tsim los ntawm cov yeeb yaj kiab dej ntawm qhov chaw, thiab cov zinc txheej uas nyob ib sab tuaj yeem kho cov xau thiab raug hlau nto, thiab txuas ntxiv ua lub luag haujlwm ntawm kev tiv thaiv.
