Study on the technology of high speed electroplating of palladium nickel alloy

针对近年研发应用于贵金属电镀行业的氨体系钯镍电镀工艺存在成本高、操作环境差等问题,研究了无氨钯镍电镀工艺,对该工艺体系镀液的工艺参数、开缸条件及镀液维护使用方法进行了研究。结果表明,无氨钯镍电镀工艺电镀液减少了对设备的腐蚀,因无氨而避免了刺激性气味的产生,利于延长阳极的寿命。该技术适用于连续镀和连续性点镀生产线,且镀层成分稳定、均匀,特别是大大降低了钯镍电镀体系的成本,成本可节约30%,生产使用期可超过5 a。

Pd-Ni electroplating process with ammonia-free was studied because Pd-Ni electroplating process in ammonia system had high cost, poor operating environment in the precious metal electroplating industry. The studies were focused on the process parameters, plating bath solution, using method and maintenance of the plating bath. The results show that the Pd-Ni electroplating process with ammonia-free reduces the corrosion of equipment and avoids the generation of irritating odor, which is beneficial to prolonging the life of anode. The utility model is suitable for continuous electroplating and continuous spot electroplating production lines, and the coating composition is stable and uniform. Especially the cost of the Pd-Ni electroplating system is greatly reduced by 30%, and the production service life can be more than 5 a.
