Abstract	Coatings of aluminium oxide Al2O3 were obtained by micro-arc oxidation under different conditions of deposition. They were analysed by such methods as: positron annihilation spectroscopy (PAS), Rutherford backscattering (RBS), X-ray diffraction (XRD) and scanning electron microscopy with microanalysis (SEM with EDS). Investigated samples showed good adhesion to the substrate, low concentration of nanopores in the bulk. Content of amorphous phase in the coating was about 20 vol.%, and metastable -Al2O3 - Al2O3 phases about less than 10 vol.%. It was demonstrated that by varying of parameters of deposition, it is possible to control the physical – mechanical properties of obtained coatings as well as their element composition and surface morphology.
