Abstract

Fundamental aspects and specific features were studied of how composite coatings with oxygen-containing compounds of manganese are formed on the surface of D16 alloy in the course of the microarc oxidation from a silicate-alkaline electrolyte in the anodic-cathodic mode with interrupted discharge. The influence exerted by the concentration of potassium permanganate in the electrolyte on the elemental composition, morphology, and structure of the coatings was examined. It was found that the coatings are promising as catalytically active and corrosion-protection systems.
