非晶态化学镀Ni-P合金镀液的研究

Physical Chemical Properties Testing of Amorphous Electroless Ni P Alloy Plating Bath

提出了非晶态化学镀Ni-P合金镀液 (ZFHN防腐蚀镀液 )质量控制的理化试验方案。采用物理试验和化学分析的方法 ,系统地分析和提出了ZFHN防腐蚀镀液性能的理化试验项目、方法、内容和分级试验方案 ;具体规定了ZFHN -Ⅱ型防腐蚀镀液的工艺参数和镀层性能指标 ,要求其缓冲容量不小于 0 .1mol/L ,密度偏差不大于 0 .0 2g/ 3 ,镀液使用寿命达到4个周期 ,镀层磷含量达到 12 % ;本方案已实际应用于镀液质量控制 ,提高了镀液工艺和镀层质量的稳定性。

Testing items, methods and contents, and classified schemes were systematically analyzed and represenued for physical chemical properties of amorphous electroless Ni P alloy plating bath (ZFHN anticorrosion plating solution). Trial tests decide detailed property indexes of bath such as buffer capacity, pH value, density and content of mail salt, as well as process parameters and performances under regulated technological conditions.
