1. Umgaqo.Ngenxa yokuba i-zinc akulula ukuyitshintsha emoyeni owomileyo, kwaye emoyeni omanzi, umphezulu unokuvelisa ifilimu ye-zinc carbonate exinene kakhulu, enokukhusela ngokufanelekileyo ingaphakathi kwi-corrosion.Kwaye xa i-coating yonakaliswa ngenxa yesizathu esithile kwaye i-matrix ayikhulu kakhulu ibonakaliswe, i-zinc kunye ne-matrix yensimbi yenza i-microcells, ukwenzela ukuba i-matrix ye-fastener ibe yi-cathode kwaye ikhuselwe.Isetyenziswa kakhulu kuthutho lwemoto kunye nakwamanye amashishini, kodwa into efunekayo yi-trivalent chromium passivation layer kunye ne-zinc-nickel alloy plating yokuvala i-coating ukunciphisa umaleko onobungozi kunye netyhefu ye-hexavalent chromium passivation.
2, iimpawu zokusebenza.I-Zinc i-coating ingqindilili, i-crystallization ilungile, iyunifomu kwaye ayikho i-porosity, ukuxhathisa okulungileyo kwe-corrosion;Icocekile, i-zinc plating layer kwi-asidi, i-alkali corrosion icotha, njengenkungu Eng ikhusela ngokufanelekileyo i-matrix yokulungiswa kwesanti, umaleko owenziwe ngegalvanized emva kwe-chromate passivation, umbala omhlophe, ohlaza umkhosi, omhle kwaye kulula, ube nesondo esithile sokuhombisa, kuba i-galvanized layer ine-ductility efanelekileyo, kwaye ngoko inokukhawuleziswa, iqhube, igobe ebandayo kwaye idale kwaye ingonakalisi isambatho.
3. Ubungakanani besicelo.Electrogalvanizingibandakanya imimandla ebanzi ngakumbi nangakumbi, iimveliso ze-fastener zisetyenziswe ngokubanzi kwimveliso yoomatshini, i-electronics, izixhobo ezichanekileyo, ishishini lemichiza, ukuthutha, i-aerospace njalo njalo kuqoqosho lwelizwe lubaluleke kakhulu.
