Сalcium-phosphate bioactive coatings on titanium
Conditions of formation of bioactive calciumphosphate surface layers, containing hydroxyapatite, on titanium using the method of plasma electrolytic oxidation in different electrolyte solutions are considered in the paper. Composition, morphology, anticorrosion and mechanical properties and composition of these coatings are investigated. On the basis of results of this investigation optimal regimes of their production are offered. Bioactive surface layers formed on the titanium implants are tested in vitro and in vivo conditions. It is shown that bioactivity of layers depends on chemical composition, specifically calcium and phosphorous concentrations, their ratio and morphology (roughness) of the surface.
