This paper has studied the dissolution behavior of the plasma sprayed and electrochemically prepared hydroxyapatite(HA) biocoatings in the simulated body fluid. XRD and SEM show that the plasma sprayed coating and post-heat treated HA coatings are more soluble, and CaO and alpha-TCP in the coatings gradually disappear and CaCO3 forms during the immersion. The composition of the electrocrystallized and alkaline-treated HA coatings is basically unchanged, and the coatings are more stable in the simulated body fluid.
