喷射电沉积块体纳米晶Co-Ni合金工艺的研究

利用扫描电子显微镜（SEM），能谱仪（EDS）及X射线衍射（XRD）等分析方法研究了工艺参数对电解液喷射电沉积法制备块体纳米晶Co-Ni合金沉积层成分及结构的影响。结果表明；在本实验条件下，随电解液喷射速度的增加，沉积层中钴含量增加，而晶粒尺寸减小；随电解液温度的升高，沉积层中钴含量减小到一定值后增大，晶粒尺寸呈相反的趋势。沉积层的表面形貌为胞状结构。

A Research on Jet-Electrodeposition of Bulk Nanocrystalline Co-Ni Alloy

The effects of the process parameters on the composition and microstructure of bulk nanocrystalline Co Ni alloy deposit prepared by jet electrodeposition are studied with SEM, EDS and XRD. The results show as the electrolyte flow speed goes up, the cobalt content in the deposit increases, but the grain size decreases under the conditions of this experiment. With the increase of the electrolyte temperature, the cobalt content in the deposit increases to a certain value then decreases while the grain size decreases to a certain value then increases. Along with the increase of cathodic current density, the cobalt content in the deposit decreases to a certain value then increases while the grain size shows a reversed tendency. The morphology of the deposit takes on a cellular structure.
