  Abstract:  Hydroxyapatite (HA) coating is the common approach to improve the biocompatibility of orthopaedic and dental titanium-based implants. Biologically active HA being similar to the mineralised bone tissue may be developed under in vivo simulated conditions. An important aspect is the ability to nucleate HA type crystals from a simulated body fluid. The effect on the bioactive phase developed on the surface of titanium-hydroxyapatite samples was evidenced by microscopic analyse after soaking for seven days in simulated body fluid. These materials are promising for developing hard tissue implants with good mechanical properties and high bioactivity.
