Morphological features and mechanical properties of coatings on AMg3 formed by plasma electrolytic oxidation
Abstract: The formation of protective oxide coatings on aluminum alloy AMg3 by plasma electrolytic oxidation was carried out. The features of the surface morphology and the internal structure of the formed layers were analyzed by scanning electron microscopy. Microhardness, Young's modulus and wear characteristics of oxide coatings have been determined.
Key word: plasma electrolytic oxidation, protective coatings, chemical composition, aluminum, duty cycle.
