Abstract
Critical parameters of the morphological development of an electrode surface at the anodic oxidation of silver-based Ag-Pd alloys are estimated. Conditions (potential range and compositions of the alloy and electrolyte solution) of the true selective dissolution of the alloys in an acidic nitrate medium are determined. The nature and kinetic parameters of the nucleation step of the phase transformation of palladium in the surface layer of Ag4Pd and Ag8Pd alloys at the over-critical potentials are found.
