Abstract
The object of research is calcium-phosphate coatings doped with Fe-Cu nanoparticles. The elemental composition of the calcium-phosphate (CаP) coatings deposited by the microarc oxidation (MAO) method at a voltage of 250 V is studied. The quantitative content and distribution of Ca, P, O, Ti, Fe, and Cu over the coating surface prove to depend on the introduced additional electrolyte components. After modification with Fe-Cu nanoparticles, the Ca content increases from 4.5 at. % to 6.7 at. %. The amount of P and Ti after the introduction of nanoparticles increases from 11.7 to 22.3 at. % and from 7.9 to 15.8 at. %. Oxygen concentration, on the contrary, decreases from 75.9 to 55.0 at. %.
