Abstract

The paper presents the results of a study of the morphology and composition of coatings on magnesium alloy MA8 obtained by plasma electrolytic oxidation (PEO) in boron-containing electrolytes. The effect of electrolyte composition and PEO modes on the elemental and phase composition, morphology and structure of heteroxide coatings has been established. It was found that with PEO in electrolytes containing boron particles, the surface of the formed coatings contains up to 2.3 at. % of boron in the bound state. It is also shown that during oxidation in electrolytes containing a dispersed phase in the form of a boron-containing suspension, inert incorporation of boron particles into the coating structure occurs.
