Influence of electrotyping temperature on the characteristics of diamond grains-nickel super-thin cutting blade

In this paper, the influence of electrotyping temperature on diamond grains content, the size of nickel crystal grains, the micro-strain and deposition rate of the film was studied. Scanning electron microscope (SEM) and X-ray diffraction (XRD) were used to analyze the characteristics of the film. It was found that diamond grains content in the film was not the same when the temperature was changed at the range of 20∼70 °C . The effect of temperature on the calculated micro-strain in the film was distinct, which indicates that the micro-strain in the film was the smallest at 50°C. Deposition rate of the film decreased with increasing of temperature. The size of nickel crystal grains also decreased with increasing of temperature. Furthermore, it was found that the growing of nickel crystal grains in the films was highly oriented when the temperature was under 40°C. The temperature influence on the characteristics of diamond-nickel composite film is discussed. These results suggest that in order to fabricate accurate diamond grains- nickel super-thin cutting blade, electrotyping temperature must be controlled at the range of 40∼50°C.
