通过改变镀液还原剂的含量和加入定量的乙酸钠，研究对化学镀镍硼合金形貌和性能的变化。从晶体结构、镀层形貌、硬度和耐磨曲线等几方面来分析加入乙酸钠12g／L时，化学镀Ni—B合金镀层形貌和性能改善的原因。乙酸钠起到缓冲剂的作用，降低了化学镀Ni—B的镀速，提高了化学镀Ni-B的致密度，改善了镀层的质量从而提高镀层的各种性能。
In order to enhance the properties of electroless Ni-B, the changes in morphology and performance of electroless Ni-B alloy was studied by changing the contents of reducing agent and adding quantitative sodium acetate. The reasons of the morphology and performance of the electroless Ni-B were improved while adding sodium acetate 12 g/L are analyzed based on crystal structure, coating morphology, hardness, wear curves. It was found that sodium acetate as a buffer can reduce the deposition rate of the chemical plating Ni-B, increase the density of the chemical plating Ni-B, and improve the quality of coating in the process.
