Electrodeposition of Palladium Coatings from Iminodiacetate Electrolyte
Abstract: The ionic composition of an iminodiacetate electrolyte as a function of solution composition and pH has been deter-mined. The kinetic parameters (exchange currents and apparent transfer coefficients) of the electroreduction of a palla-dium(II) bis-iminodiacetate complex from an electrolyte containing excess ligand have been calculated. It has been shown that the rate of the electrode process is controlled by the diffusion of reduced ions to the electrode surface and by the electron-transfer reaction. The possibility of using iminodiacetate electrolyte for palladium plating for the deposition of fine-crystalline adherent and ductile palladium coatings has been examined.
