Nanoscale Bonding between Human Bone and Titanium Surfaces: Osseohybridization

Figure 9

Phosphorus L-edge spectra of (a) the interface layer and (b) the bone tissue layer. The P L-edges have peak positions and shapes similar to those of calcium phosphate in both layers. However, we cannot differentiate between tricalcium phosphate and hydroxyapatite from the P L-edge.
