The aim of this work is to study the chemical composition of Ti anodic oxides grown in phosphoric acid, followed by the electrodeposition of calcium and phosphorous compounds. The modified surfaces were characterized by Raman spectroscopy and SEM to identify the chemical species present and their crystallographic phases as well as the general morphology of the surface. Phosphate was detected on the anodised samples previous to electrodeposition, indicating its incorporation from the anodising solution. Hydrated calcium phosphate (brushite) was also identified on the surface after electrodeposition.
