Thaum cov khoom siv hlau tau muab tso rau hauv cov zinc molten, ib qho kev daws teeb meem ntawm zinc thiab hlau thawj cov ntaub ntawv ntawm lub interface, uas yog cov txheej txheem ntawm zinc dissolving thiab diffusing rau hauv cov hlau matrix. Raws li zinc txuas ntxiv nkag mus, hlau thiab zinc ntxiv rau kev tsim cov intermetallic compound FeZn13, uas nkag mus rau hauv qab ntawm lub lauj kaub thiab tsim zinc slag. Nyob rau tib lub sij hawm, ib txheej ntawm cov zinc ntshiab cov ntaub ntawv nyob rau saum npoo ntawm cov hlau tivthaiv, uas crystallizes thiab solidifies thaum txias, tsim ib tug tiav galvanized txheej.
