Study of Roughness for Electroplating of Composite Texture on Material Surface

Abstract:

In this paper, the intermediate layer was prepared by electroplating of nickel and WC particles. The parameters, including current density and temperature, were studied in the experiments. The measured methods, which consisted of surface roughometer and SEM, were used to character the roughness and microstructure. The experimental results showed that the optimizing parameters of the electroplating for composite texture were as follows, temperature was 65°C, current density was 5A/dm² and the pH value was 6.5. Under the condition of optimizing parameters the values of roughness Ra were in the range from 4.5 to 6.7 μm. From the microstructure observation by SEM revealed that the particles on the surface were well distributed. The difference of the electroplating time induced the different nickel contents which affected the binding force. The roughness of the surface was in the range of 1.35 to 4.47 μm.
