Abstract
In the presented study, changes in the wettability and corrosion properties of composite coatings formed on the MA8 magnesium alloy by plasma electrolytic oxidation (PEO) with subsequent treatment with organofluorine polymers were investigated after accelerated climatic tests in a salt spray chamber. It was found by the sessile drop method that after accelerated climatic tests the contact angle decreases by 2.5 times for PEO coatings, and by 15o for composite coatings. Evaluation of the electrochemical properties of the composite layers revealed an insignificant decrease in the value of the corrosion current density after 40 days of holding samples in a salt spray chamber.
