Abstract: |
The copper were plated in 40 ℃, 0.4 A/dm2 and 2min, by changing the content of the nickel sulfate in the bath. And then,determinating the coating composition and the parameter L, a ,b of the color. Analysising the wear resistance,corrosion resistance of the coating with the SEM. The result shows that the L is less than 40, which means that the coating is ukrainian black. With the content of the nickel sulfate increasing,the coating is blacker in trend, and also, the anti-tarnish resistance, wear resistance,corrosion resistance are improved.
