摘要：
To evaluate the application of mirror-bright silver deposit from 5,5-dimethylhydantoin (DMH) and nicotinic acid (NA)-based cyanide-free silver electroplating bath, the performance comparison of cyanide-free silver deposit obtained from the introduced bath with conventional cyanide-based one was carried out. The macroscopic appearance, surface morphology, adhesive strength, and welding property of the introduced mirror-bright silver deposit were determined. Equal to the cyanide-based silver electroplating bath, mirror-bright silver deposits with excellent leveling capability, and smooth and compact morphology, as well as excellent welding property could be obtained from the studied DMH and NA-based silver electroplating bath. Thus, the investigated DMH and NA-based silver electroplating bath could be a promising alternative to the conventional cyanide ones for the applications of silver electroplating in decorative purposes and microelectronics.
