| Abstract: |
| The Fe-Cr-Ni coating was electrodeposited from chloride-sulphate electrolyte. The effect of the content of Cr in electrolyte on the electrochemical corrosion behavior of electrodeposited Fe-Cr-Ni coating in NaCl solution was investigated. The results show that the corrosion potential of the coating is negative when the content of Cr is lOOg/L during immersion test. In addition, the coating shows passivation behavior. When the content of Cr is lOOg/L in the electrolyte, the coating shows overpassivation phenomenon, and then the coating exhibits poor corrosion resistance. |
