摘要：
Analytic equations describing the concentration profile, surface energy, and adsorption for a binary solid solution with the emergence of one of the components to the surface (surface segregation) were obtained using a unique approach, a modified van der Waals approximation. The calculation results were compared with the experimental secondary ion mass spectrometry data on Cu-Ge and Cu-Al metallic binary solutions; agreement was satisfactory.
