Silver Electroplating
Ag+ + e− → Ag
概要
Silver ions from a silver cyanide or silver nitrate bath are reduced at the cathode, depositing a thin, bright layer of metallic silver. Silver plating provides excellent electrical conductivity, antimicrobial properties, and a lustrous finish. The process requires careful control of current density and bath composition.
