Plasma Electrolytic Oxidation (PEO) Coatings

Plasma electrolytic oxidation (PEO) also known as micro-arc oxidation (MAO) functionalizes surfaces improving the mechanical thermal and corrosion performance of metallic substrates along with other tailored properties (e.g. biocompatibility catalysis antibacterial response self-lubrication etc.). The extensive field of applications of this technique ranges from structural components in particular in the transport sector to more advanced fields such as bioengineering. The present Special Issue covers the latest advances in PEO‐coated light alloys for structural (Al Mg) and biomedical applications (Ti Mg) with 10 research papers and 1 review from leading research groups around the world.
