摘　　要：描述了针对雷达刷丝-导电环采用钯镍合金镀膜的技术,对铝青铜材质的导电环刷丝面进行电镀,达到耐磨性钯镍合金膜层结构,以满足产品所需要的耐磨和导电要求。研究了钯镍合金溶液的钯离子浓度参数变化,以及参数变化对刷丝面镀层钯镍百分比含量的影响。结合镀金层对实验结果进行分析,讨论了各种现象出现的原因。Palladium nickel alloy technique is adopted for the radar brush wire conductive ring. Metallization is conducted on aluminum bronze material of conductive ring to wear resistance palladium nickel alloy membrance layer structure, so as to meet the wear-resisting and conductive requirements. The palladium ion concentration parameter change in the palladium nickel alloy solution and its influence on brush w.ire surface thickness is studied. Combined with the experiment results of gold plated layer, the article analyzes the reasons of various phenomena.
