Article Preview

In this study we report on the microstructure and its mechanical behavior of a Ca-P coating produced on bioactive titanium by immersion in a simplified simulated body fluid (S-SBF). The coating was probed by nanoindentation in several point times up to the formation of octacalcium phosphate (OCP). Amorphous calcium phosphate, formed after 1h of immersion in SSBF, presented the highest values of hardness (H) and elastic modulus (E). Nucleation of OCP was observed after 2-2,5h of immersion in S-SBF. From this stage on, lower values of H and E were obtained, probably due to the low dense structure of the coating.
