N2 - The surface layers of the intermetallics ANiAl (A = Zr, Y, U), exposed to the ambient air, residual gases and oxygen, were investigated by X-ray photoelectron spectroscopy. The surface and the oxidation energies of the metal components were considered as the possible driving forces for the surface decomposition. A "rule of reverse stability" exists for the three isostructural compounds, i.e., the less stable one (UNiAl) exhibits the most significant segregation. An extrapolated degree of segregation of the air-exposed intermetallics yields a good agreement with previously proposed quantitative model.
