为了进一步提高烟酸镀银的光亮性，改善镀液的性能，通过赫尔槽试验研究了2，2-联吡啶与硫代硫酸钠对镀层外观的影响，并用金相显微镜观察基础配方和优化配方的镀层的表面形貌。

The causes of tarnishing gold and silver-plated connectors were studied respectively.

分别探讨了接插件镀金和镀银层变色的原因。

It is found that the ploating structure of copper power is related to mechanism of nucleus forming and content of silver;Thermal stability is affected by plating structure of silver-coated copper power.Silver-coated coppe...

结果表明：铜粉表面镀层结构与银离子形核长大机制和银含量有关；镀银铜粉的热稳定与表面镀层结构有关；完全包覆结构的镀银铜粉具有较好的热稳定性，抗氧化温度可以达到800℃以上。

And a relatively ideal process is obtained: AgNO3 20g/L, NH3·H2O 80ml/L, KNaC4H4O6·4H2O 100g/L with PH value 12.5 and plating temperature of 20℃, from which we get an even, dense and well-combined silver-plating layer.

得到的镀银层均匀致密，结合良好。

This article is the first report on the study of "pulse silver plating".
