介绍了一种制备块体纳米晶Ni-W合金的电铸工艺,该工艺具有最小的W浓度梯度和波动。通过能量色散X射线能谱(EDS)的线性分析得到的W浓度分布,保证了W浓度在微米级和毫米级的均匀性。结合电感耦合等离子体质谱(ICPMS)的实验结果和微分方程组的精确解,对电解液中的金属离子进行了质量平衡分析。首次制备了厚度大于2 mm的均匀块体纳米晶Ni-W合金。
An electroforming process for fabricating bulk nanocrystalline Ni-W alloys with minimizing W-concentration gradient and fluctuation is presented. The homogeneities of W-concentration in both micrometer scale and millimeter scale are guaranteed from the W-concentration profiles obtained by the linear analyses of the energy dispersive x-ray spectroscopy (EDS). Mass balance analyses of the metallic ions in the electrolyte are performed by the combination of the experimental results of the inductively coupled plasma mass spectrometry (ICP-MS) and the exact solutions of the simultaneous differential equation. The homogeneous bulk nanocrystalline Ni-W alloy with the thickness above 2 mm is featured for the first time.
