Abstract: The results of new studies of creating protective oxide coatings based on Al$_2$O$_3$ (Si, Mn) and deposited onto aluminum alloys using electrolyte-plasma oxidation are presented. An analysis is performed by scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), X-ray diffraction, Rutherford backscattering of $^4$He$^+$ and protons, nanoindentation, scratching, friction coefficient measurements, and acoustic emission measurements. The results demonstrate that the deposited coatings have a high quality, hardness, and wear resistance and a low thermal diffusivity. Apart from Al$_2$O$_3$, the coatings are found to have Si, Mn, C, and Ca. The stoichiometry of the coatings is determined. The density and hardness of the coatings are close to those of $\alpha$-Al$_2$O$_3$ in the coating on an Al–Cu (D-16) substrate, and these values of the coating on an Al–Mg (S006) are lower by a factor of 1.5.
