In this paper the authors have studied by a pulse potentiostatic method the selective dissolution (SD) of Pb-In (5, 10, 20 at .%), Sn-In (0.5, 1, 2.5, 4, 17 at .%), Ag-Cd (30 at .%), and Sn-Zn (1 at .%) alloys at potentials which are sufficient only for the dissolution of the electronegative component (ENC). Also considered is the effect of the ENC concentration in the alloy, of the duration of the SD process, and of the melting point of the alloy on the quantity D /SUB A/ (diffusion constant of ENC component A in alloy A-B). The experiments were carried out in deaerated solutions at 20/sup 0/C. Features of solid-phase diffusion of the A atoms during the SD of alloy A-B are described.
