Progress on Hydrothermal Synthesis of Biomedical Coatings on Magnesium Alloy

Abstract

Hydrothermal synthesis as a new coating technique has been developed to produce biomedical coating in Mg alloys in recent years. This paper summarized the process feature and corrosion resistance of hydrothermal synthesis coating in Mg alloys, and then reviewed the synthesis process, microstructure, corrosion behavior and corrosion mechanism of the Mg (OH)2 biomedical coatings. Finally, the current problems and research prospect of this technique in biomedical Mg alloys were discussed.
