Abstract
ABSTRACT A Simulated Body Fluid (SBF) treatment was performed to modify the surface of a TiO2-based coating containing Ca and P prepared by micro-arc oxidation (MAO). Scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-Ray Photoelectron Spectroscopy (XPS) were employed to characterise the composition and morphology of the immersed Ca-P containing coating. The coating primarily presents a porous structure, which is mainly composed of anatase, rutile, CaP, and Nb2O5.The biological activity of the coating was determined by immersing in SBF for 5 days, showing hydroxyapatite (HA) formed on the surface of the coating and also revealing the good corrosion resistance of the coating in SBF. Finally, a lower MAO coating contact angle with SBF solution than that of TLM Ti alloy was obtained in the compatibility test, indicating that the coating has good compatibility with SBF.
