Abstract
Using the buy-to-fly ratio for sprayed material, we optimized the method of creating nanostructured plasma coatings based on hydroxyapatite. After plasma spraying, the coating contains 67–83% hydroxyapatite phase. We studied several case of hydrothermal treatment of coatings for the purpose of strengthening them and in order to increase the hydroxyapatite phase content. After hydrothermal treatment of the coating at 650°C, we achieved the value of hydroxyapatite content around 98%. The size of coherentscattering regions grew from 95 to 122 nm. We proved that, after the treatment, the shear strength of hydroxyapatite-based coatings in relation to the titanium substrate is 22.3 MPa.
