摘要:
分别采用以丁二酰亚胺和亚氨基二磺酸铵为主配位剂的两种无氰镀银液，通过电刷镀工艺成功在紫铜基体表面制备出了镀银层。通过 X 射线光谱法、 SEM 、 EDS 、显微硬度及摩擦磨损实验等分析方法，对镀银层外观、厚度、微观形貌、硬度以及摩擦磨损性能等方面进行了分析及比较。结果表明：两种体系制备出的镀银层外观均平整光亮，厚度及硬度均满足 Q/GDW 11718.1 - 2017 标准中的要求，磨损机制均为黏着磨损及磨粒磨损，其中丁二酰亚胺体系镀液制备出的镀银层性能要优于亚氨基二磺酸铵体系，其微观表面更加平整，颗粒排列更加致密，镀层厚度均值达 28.24 μ m ，硬度均值达 135.4 HV ，磨损速率为 0.1375 mg/m 。
Abstract:
Silver coating was successfully prepared on copper substrates by electro-brush plating with succinimide and ammonium iminodisulfonate as main complex agents respectively. The appearance ， thickness ， micro morphology ， hardness ， friction and wear properties of the silver coatings were analyzed and compared by means of X-ray spectroscopy ， SEM ， EDS ， microhardness test ， friction and wear test. The results showed that the silver coating prepared by the two systems had smooth and bright appearance ， the thickness and hardness met the requirements of Q/GDW11718.1 - 2017 standard ， and the wear mechanism was adhesive wear and abrasive wear. By comparison ， the performance of silver plating layer prepared by succinimide system was better than that of ammonium iminodisulfonate system. The micro surface was smoother ， the particle arrangement was more compact ， the average thickness of the coating was 28.24 μ m ， the average hardness was 135.4 HV ， and the wear rate was 0.1375 mg/m.
