The purpose of the work was to make a non-destructive layer-by-layer analysis of changes in the energy structure of valence electronic states, determine the thickness of the oxide layers that form and estimate the distribution of composition and chemical binding of elements over the depth. The method of ultrasoft X-ray emission spectroscopy with variation of the electronic excitation energy was used in a study of alloy Al-2. 0 wt. percent Mg after heat treatment in air for times from 4 min to 4 hr at 530 degree C. The depth of the MgO layers formed on the surface and the type of magnesium and aluminum oxide distributions over the depth were determined.
