The processes of surface segregation of components in hard Sn-Pb alloys by electron Auger spectroscopy have been studied. The amplitudes of Sn and Pb Auger peaks in the spectra of solid alloys were measured. Calculations of the surface composition of lead at different volume concentrations and temperatures have been carried out using the experimental data, which made it possible to study the segregation of lead due to changes in these parameters. It was determined that in solid β-solutions surface activity of tin is observed, while in α-solutions significant lead segregation was established. Thus, for solid solutions of 0.12 and 0.22 at. % Pb, a surface concentration of Pb more than 100 times higher than its bulk content is observed.
