pH值对金刚石表面化学镀镍的影响
Effect of pH Value on the Electroless Nickel Plating on Surface of Diamond
摘要
Abstract
Nickel metal layer was plated on the surface of diamond particles by chemical plating method is the background of this paper. The structure, microstructure and plating rate was changed by the pH vale of plating bath, which was investigated through XRD and SEM analysis. The results show that the plating rate almost was zero and no reaction can occur when the pH below 10. 5. When the pH value was between 10.5 and 12, the plating rate increating with the increased of the pH vale, the plating rate was increased faster, the Ni peaks in X-ray diffraction patterns of plating was found, the peak intensity enhancing with the increased of the pH value and the substrate was not covered of Ni plating completely. The plating rate remained steady when the pH value was about 13, the Ni peaks in X-ray diffraction patterns of powders was more strong, the substrate was coating of Ni plating completely, the plating was dense and uniformity. The plating had an exfoliation phenomenon and relatively roughness until the pH value closed to 14. The double-plating was be carry out under the conditions of the pH 13, the plating thickness was about 1.5 μm, the coating was more dense and closely.关键词
