- Аннотация: A model is suggested for describing the kinetics of a diffusion exit of atoms of the surface-active component of binary alloys of the solid solution type into a surface layer. An impedance method is used to study the dependences of the differential capacitance of the electrical double layer on the potential on renewable-by-mechanical-cut electrodes made of alloys of the system Ag-Sn (1 and 3 at. % Sn) in solutions of NaF. It is established that with increasing duration of contact of a renewed surface of electrodes with a solution of an electrolyte there takes place a very rapid process of predominant exit of tin atoms into a surface layer. It is shown that the observed temporal effects are quite satisfactorily described by the model suggested. Additionally, direct data about the accumulation of tin atoms in a surface layer of alloys studied are obtained by an XPS method.
