Formation of composite coatings by plasma electrolytic oxidation using fluoroparaffines
Protective composite coatings formation method on a magnesium alloy using plasma electrolytic oxidation (PEO) and fluorocarbon materials has been considered. The composite coatings have protective anticorrosion and wear-resistant properties: the corrosion current density decreases by more than two orders of magnitude, and the wear decreases by an order of magnitude than the base PEO coating. It has been established that coatings of surface have hydrophobic properties. Values of the contact angle changed in the range from 122° up to 137°, depending on the fluorinated paraffin type.
