摘要
采用正交实验优化了玻璃表面低磷化学镀镍工艺,获得的最优组成为:柠檬酸钠15 g/L,氯化铵20 g/L,次磷酸钠30g/L,pH值8。采用扫描电镜(SEM)、能谱成分分析(EDS)和X射线衍射(XRD)等方法对镀镍层的表面形貌、镀层成分及物相结构进行了分析。结果表明:在最佳组成条件下所得的镀层具有致密的胞状组织,磷的质量分数为1.78%,属于低磷镀层,镀层为微晶态结构。
The process for electroless nickel plating of low-phosphorous on glass was optimized by orthogonal experiment.The optimal parameters obtained are： sodium citrate 15 g/L,ammonium chloride 20 g/L,sodium hypophosphite 30 g/L,pH 8.The morphology,composition and phase structure of the Ni-P deposit were analyzed by the XRD,SEM and EDX techniques.The results show that the Ni-P coating obtained under the optimal conditions has a compact cellular structure,of which the phosphorus mass fraction is 1.78 %,belonging to low-phosphorous coating with a microcrystalline structure.
