Flow Plating Process of Amorphous-nanocrystalline Composite Structured Ni-P Alloy

Keywords： flow field , Ni-P alloy , phosphorus content , deposition rate

非晶纳米晶Ni—P合金由于其良好的综合性能得到广泛应用，流动镀技术由于可大幅提高沉积速度而受到极大关注。本工作研究了电解液流速、阴极电流密度和阴阳极间距等工艺参数对镀速、Ni-P合金P含量和表面形貌的影响规律，并初步探讨了各工艺参数对电化学沉积过程的影响机理。

Amorphous-nanocrystalline composite structured Ni-P alloys were widely used in many fields due to their good combination properties. Flow plating receives more attentions as it can improve the deposition rate. In this woric, the influence of electrode distance, current density of cathode and flow rate of electrolyte on the deposition rate, phosphorus content and morphology of the Ni-P deposits was investigated by changing the different technology conditions. The effect mechanism of different technology factors on the course of electrodeposition was also discussed. :
