DC plasma electrolytic oxidation of biodegradable cp-Mg: In-vitro corrosion studies

► Biocompatible DC-PEO coatings on Mg containing Mg3(PO4)2 and/or MgO ► Substituting KOH with Ca (OH)2 or Ca (NO3)2 improves in-vitro corrosion resistance. ► Diffusion processes influence coating corrosion behaviour in SBF.
