Corrosion passivation of magnesium alloy with the duplex coatings of plasma electrolytic oxidation and tetrafluoroethylene-based polymers

In view of insufficient protection against corrosion provided by plasma electrolytic oxidation (PEO) coating on magnesium alloys, we have prepared and analyzed the duplex PEO coatings using the polytetrafluoroethylene (PTFE)-based polymer. Four duplex coatings have been prepared to compare with the...
