Formation of structural, physical and adhesive properties of calcium-phosphate biocoatings on the microarc oxidation process with nanocomposite particles Fe-Cu
In this work, a method for modifying calcium phosphate coatings formed by microarc oxidation by adding nanocomposite bicomponent Fe-Cu particles to the electrolyte has been proposed. The effect of modification by Fe-Cu nanoparticles on the morphological, structural and mechanical characteristics of calcium phosphate coatings on titanium has been evaluated. It has been established that coatings possess the highest adhesive strength (33 MPa) with a thickness of 42-50 μm, formed at a voltage of the MAO process of 200 V in an electrolyte with the addition of Fe-Cu nanoparticles. These coatings are characterized by a roughness (Ra of 3.3 μm, a surface porosity of 21% and higher, in comparison with the unmodified coating, calcium content.
