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.
