Usoro nhazi nke oyi akwa galvanized na-ekpo ọkụ bụ usoro nke ịmepụta ígwè-zinc alloy n'etiti ígwè matrix na n'èzí zinc oyi akwa.Elu nke workpiece na-etolite oyi akwa ígwè-zinc alloy n'oge ntinye ọkụ na-ekpo ọkụ, nke mere na a na-ejikọta ígwè na akwa zinc dị ọcha.Usoro nke nnukwu mpịakọta galvanized waya nwere ike nanị kọwara dị ka: mgbe ígwè workpiece na-mikpu n'ime a wụrụ awụ zinc ngwọta, mbụ zinc na α-ígwè (ahụ na-adabere) siri ike gbazee na-guzobere na interface.Nke a bụ kristal kpụrụ site na matriks metal ígwè gbazere na zinc atọm na steeti siri ike.Atọm ọla abụọ a na-ejikọta ibe ha, na mma ndọda dị n'etiti atọm ahụ pere mpe.
Ya mere, mgbe zinc ruru saturation na agbaze siri ike, ihe abụọ nke zinc na ígwè atom na-agbasa n'otu n'otu, na zinc atom na-agbasa n'ime (ma ọ bụ banye n'ime) ígwè matrix na-akwaga na lattice nke matriks ma jiri nwayọọ nwayọọ na-etolite. ihe alloy na ígwè, mgbe ígwè na-agbasasị n'ime zinc a wụrụ awụ mmiri mmiri na-etolite intermetallic compound FeZn13 na zinc na imikpu n'ime ala nke na-ekpo ọkụ galvanized ite, ya bụ, zinc slag.Mgbe ewepụrụ workpiece na zinc leaching ngwọta, a na-emepụta elu nke akwa akwa zinc dị ọcha, nke bụ kristal hexagonal, na ọdịnaya ígwè ya abụghị ihe karịrị 0.003%.
Galvanizing na-ekpo ọkụ na-ekpo ọkụ, nke a makwaara dị ka ihe na-ekpo ọkụ na-ekpo ọkụ, bụ ụzọ e si enweta ihe mkpuchi ígwè site n'itinye onye nchara nchara n'ime ngwọta zinc a wụrụ awụ.Site na mmepe ngwa ngwa nke nnyefe voltaji dị elu, njem na nkwurịta okwu, ihe nchebe chọrọ maka akụkụ ígwè na-adịwanye elu, na ọchịchọ maka galvanizing na-ekpo ọkụ na-arịwanye elu.Na-emekarị ọkpụrụkpụ nke electric galvanized oyi akwa bụ 5 ~ 15μm, na nnukwu mpịakọta galvanized waya oyi akwa bụ n'ozuzu karịa 35μm, ọbụna ruo 200μm.Galvanizing na-ekpo ọkụ na-ekpo ọkụ nwere ikike mkpuchi dị mma, mkpuchi dị oke na enweghị ntinye organic.
