Induction heating/hydrothermal treatment is a novel technology for preparing a well bonded and covered coating on conductive materials. In this study, induction heating method was first used to deposit a monetite coating on pure magnesium, and then hydrothermal treatment was applied to convert the monetite to a hydroxyapatite (HA) coating. The composition, structure and morphology of the coatings on magnesium were characterized by EDS, XRD, and SEM. the adhesive properties between the HA coating and Mg substrate were examined by a scratch test, and the biodegradation performance of the HA coated and uncoated Mg was determined by immersing in a 3.5% NaCl solution through electrochemical experiments. The results showed that the as-achieved sample contained a compact double-layer structure with Mg(OH)2 as an inner layer and HA as a top layer. This composite coating can obviously slow down the biodegradation rate of pure magnesium, and the bonding strength could reach a critical load of 6.08 N for HA layers and 21.52 N for Mg(OH)2 layer, respectively.
