Plasma electrolytic oxidation treatment of magnesium alloys
C. Blawert and P. Bala Srinivasan, GKSS-Forschungszentrum Geesthacht GmbH Geesthacht Germany
Plasma electrolytic oxidation (PEO) is an attractive surface engineering process for magnesium alloys. During PEO, the surface of a magnesium alloy is converted into a hard ceramic coating, in an electrolytic bath, using high energy electric discharges. This can offer improved wear and corrosion resistance to various magnesium components, thus expanding their fields of application. In this chapter, various aspects of PEO of magnesium alloys, such as the basics, processes, properties and applications, are discussed and the current status of the PEO of magnesium alloys is overviewed. ...
