| Abstract: | Cu snbstrate was coated with Ni-Co-Cr alloy coatings through electrodepositinn. Citric acid, boric acid and sodium lauryl sulfate versus the coatings properties were investigated. The corrosion resistance and adhesive property of the coatings were assessed using electrochemical impedance and bending test. The results indicate that the corrosion resistant performance of alloy coating is the best under the deposition condition that the concentration of sodium citrate is 200 g/L, the boric acid＇s is 40 g/L, the saccharin＇s is 1.4 g/L, and the sodium dodecyl sulfate＇s is 0.18 g/L. |
