| Аннотація | Plasma Electrolytic Oxidation (PEO) was performed on Ti in electrolyte containing calcium acetate monohy-drate (Ca(CH3COO)2(Ca (CH3 COO)2 H2O)H2O) and sodium phosphate monobasic dehydrate (Na2HPO4(Ca (CH3 COO)2 H2O)2H2O) using a pulse power supply. Scanning electron microscopy (SEM) with EDS and X-ray diffraction (XRD) were employed to characterize the microstructure, elemental composition and phase components of the coatings. All oxidized coatings contained Ca and P as well as Ti and O, and the porouscoatings were composed of anatase, rutile and hydroxyapatite. After hydrothermal treatment, the hydroxyapatite was precipitated on the surface of the sample plate obtained by PEO and the hydroxyapatite thickness was about 15 µm |
