- 摘要:
- 以氯金酸无氰电沉积体系为基础，以添加剂作为单一变量进行电沉积金样品的制备和分析。添加剂对氯金酸体系电沉积金层的性能有明显影响，不同添加剂条件下电沉积金层的晶粒尺寸、晶面织构系数、维氏硬度值均存在差异。组合添加剂条件下样品性能表现最佳，电沉积金层宏观特征最好，光泽和平整度较好，样品晶粒尺寸为 42.0 nm ，呈（ 220 ）晶面的择优取向，其织构系数高达 88.62% ，维氏硬度值高达 115.8 HV 。
- Abstract:
- ： Based on cyanide-free chlorauric acid electrodeposition system ， the electrodeposition gold samples were prepared and analyzed with additive as a single variable. The additive has obvious effect on the properties of the gold layer. The grain size ， texture coefficient of crystal plane and Vickers hardness of the gold layer are different under different additive conditions. Under the condition of combined additives ， the sample has the best performance ， the electrodeposited gold layer is dense and smooth ， and has good glossiness. The grain size of the sample is 42.0 nm ， and the sample has the preferred orientation of （ 220 ） crystal plane. The texture coefficient of （ 220 ） crystal plane is up to 88.62%. The Vickers hardness value of gold layer can reach up to 115.8 HV.
