- 为解决由于电流密度分布不均导致的电铸镍片厚度不均匀性问题，研究了电铸工艺参数和阴极挂具结构对改善镍片厚度均匀性和电铸结瘤状况的影响。结果表明，当电流密度为 11 A·dm -2 、阳极长度为 3.5 cm 、极间距为 2.5 cm 、温度为 45 ℃ 时，镍片厚度均匀性最好。此时厚度平均值为 0.484 mm ，极差和均方差分别为 0.157 mm 和 0.044 mm 。在最佳工艺参数下，改善挂具和设计阴极遮蔽，解决了接触点厚度薄的问题，结瘤缓解，电铸时间由 10 h 缩至 4 h ，厚度极差和均方差分别降至 0.116 mm 和 0.036 mm 。实验确定的最佳工艺条件不仅提高了镍片厚度均匀性，电铸时间也缩短了 60% ，提升了阳极镍粒的利用率，节约了电铸成本。
- Abstract:
- ： To address the issue of the thickness non-uniformity of electroformed nickel plates resulted from uneven current density distribution ， this study investigated the impact of electroforming process parameters and cathode fixturing structure on enhancing the uniformity of nickel plate thickness and mitigating dendritic growth. The results show the uniformity of nickel sheet is the best when the current density is set at 11 A·dm -2 ， the anode length at 3.5 cm ， the electrode spacing at 2.5 cm ， and the temperature at 45 ℃. The average thickness is 0.484 mm ， and the range and standard deviation of thickness decreases are 0.157 mm and 0.044 mm ， respectively. Forthermore ， by optimizing the rack design and introducing cathode shielding ， thickness at the contact points is enhanced and nodular can be alleviated. The electroforming time can be shorted from 10 h to 4 h. Moreover ， the thickness range and the standard deviation are reduced down to 0.116 mm and 0.036 mm ， respectively. The optimal conditions obtained brings about the homogeneous thickness of the nickel sheet and a 60% reduction in the electroforming time. These improvements increase utilization ratio of anode nickel shots ， thereby contributing to cost savings.
