Abstract

The paper presents a study of the properties of layers formed on magnesium alloy MA8 by plasma electrolytic oxidation (PEO) in boron-containing electrolytes. The electrochemical properties of the coatings were investigated by electrochemical impedance spectroscopy. The mechanical characteristics of the coatings were estimated by the values of microhardness and Young's modulus. It is shown that samples with coatings formed in potentiodynamic modes are superior in terms of corrosion resistance to an uncoated alloy by more than 1 order of magnitude. The introduction of boron particles into the composition of coatings makes it possible to improve the mechanical properties: The universal microhardness of coatings with particles exceeds by 10-12% the value of this parameter for basic PEO coatings.
