F- and P-enriched Coatings for Mg Implants by Low Energy PEO Process

Abstract

Degradable implants occupy the significant position in orthopedic industry. Magnesium is an appropriate degradable material due to its good biocompatibility and degradability properties in addition to advantageous mechanical properties. Improving the material quality, especially corrosion resistance and surface active, could be occur through the chemicals and parameters of the Plasma Electrolytic Oxidation process. Voltage reduction could reduce cost involved and make more environmentally friendly. Doubling the concentration of the sodium phosphate worked at low voltage. The surface morphology showed well-developed structure. Obtained coatings were without cracks and with good thickness size. Increasing wettability point to enhancing bioactive properties.
