Process and mechanism of electrodeposited Zn-Fe-Si02 composite coatings were studied, including some contents as follow: Potential-pH plots of Zn-H2O and Fe-H2O systems were drawn, and the thermomechanical analysis was made. Results showed that the region of zinc and iron's codeposition was wide, which provided theoretic basis for electrodepositing Zn-Fe alloy. But the balance potential of zinc was greatly different from iron's, so in order to make zinc and iron codepositing, some complexant must be added into electroplating solution.
