Abstract: This paper considers the conditions of thebinary alloys $\mathrm{Cu}$-$\mathrm{Ag}$ free surfaces judging by the images obtained by means of a scanning electron microscope. The initial distribution of alloy components, studied by temperature programming desorption method, were analyzed. The solid solution layering to $\mathrm{Cu}$ and $\mathrm{Ag}$ rich phases was confirmed. Their evolution depending on $\mathrm{Ag}$ volume content was observed.

Keywords: temperature-programming desorption, mass-spectrometry, surface, surface phases, $\mathrm{Cu}$-$\mathrm{Ag}$ binary alloy, scanning electronic microscope.
