Abstract:Fluoridated hydroxyapatite (FHAp) coating was directly fabricated on AZ91D magnesium alloy without using any chelating agents by a facile hydrothermal method. The results show that the as-prepared coating is mainly composed of FHAp and magnesium whitlockite. The morphology of the FHAp coating is changed with the increase of the F- ion doping amount, and the FHAp-0.04 coating has a much uniform and dense structure than the FHAp-0.02 coating. The FHAp coating can remarkably reduce the corrosion rate of the substrate in simulated body fluid (SBF) solution, particularly during the initial immersion stages. Moreover, the FHAp coating can also induce the formation of apatite particles after being immersed in SBF, indicating the good bioactivity of the coating.
