Synthesis of calcium phosphates on titanium

Abstract

On the basis of studying the phase and elemental composition of calcium phosphate coatings deposited on titanium by anodic spark oxidation from aqueous solutions, a mechanism of formation of bioactive ceramic components is proposed. The effect of the solution composition and the deposition time on the thickness and porosity of the coatings is studied. It is shown that an increase in the coating thickness leads to a decrease in the coating porosity and that the Ca/P ratio in the coatings hardly depends on the concentration of tricalcium phosphate solubilized with sodium complexonate.
