Characterization of anodic spark-converted titanium surfaces for biomedical applications

The aim of the present study was to characterize the surface morphology, microstructure and the chemical composition of anodic spark-converted titanium surfaces. The coatings were prepared in an electrochemical cell by the anodic spark deposition technique in an aqueous solution of Ca(H2PO4)2. The coatings were characterized by X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), electron probe microanalysis (EPMA) and X-ray diffraction (XRD). The properties of the coatings are described in terms of morphology.
