On the base of the phasic and elemental analysis of calcium-phosphate coatings, obtained on titanium by anodic spark oxidation from aqueous solutions, the assumption of the formation mechanism of bioactive ceramics was made. The influence of the electrolyte composition and deposition time on the porosity and coating thickness was investigated. It was shown that the higher the coating thickness, the less the coating porosity. In addition, it was revealed and confirmed that the atomic ratio of Ca/P in coatings does not depend on the concentration of tricalciumphosphate, transformed into a soluble form by sodium complexonate.
Keywords: titanium, calcium-phosphate coating, anodic-spark deposition.
