Critical Value

Cu-Ni-W alloy coating was electroplated on the surface of mild steel and the effect of Cl- concentration on its corrosion behavior was evaluated in this paper. Polarization techniques and electrochemical impedance spectroscopy (EIS) have been used to investigate the corrosion behavior in aqueous solution contain various Cl-. The results showed that The increased Cl- is prejudice for the Cu-Ni-W coating from 0.01 to 0.3 mol/L, and the critical value of Cl- content is 0.3 mol/L, the coating corrosion present better resistance when immerse in the solution with Cl- content exceeds the critical value or more .
