Physical Chemistry of Surface Phenomena


The kinetics of oxidation of the surface of Al alloys with 1–2.5 at % rare-earth metals (REMs) at 400–500°C in air was studied by ellipsometry and X-ray photoelectron spectroscopy (XPS). The addition (1–2.5 at % REM) of all rare-earth metals to aluminum was shown to increase the thickness of the oxide layer. The addition of surfactant and chemically active REMs (Yb, Sm, La, and Ce) increased the rate of oxidation of solid aluminum most effectively. The oxidation can be accelerated by the polymorphic transformations of the individual REM oxides in the film. The surface activity of Sm with respect to solid Al was confirmed by XRS.
