implantation[1]. In the past decades, several coating methods have been developed to deposit HA onto titanium surface, including plasma spraying, ion beam sputtering, sol-gel, electrophoretic deposition... and mechanical properties. However, titanium exhibits poor osteoinductive properties, fortunately, which has been resolved recently by coating the metal with a layer of bioceramic, especially......
