Abstract

A self-assembled monolayer (SAM) technique was employed to produce carbonate apatite (CA) coatings onto Ti substrates after sulfonation. The Ti substrates thus treated (S-SAM-Ti) were immersed in metastable calcium phosphate solutions containing carbonate to induce precipitation of carbonate apatite on the surface. The uniformity and homogeneity of the CA layer was partly demonstrated by the XPS crater-edge-line analysis. Both calcium and phosphorus were distributed quite evenly within a layer of approximately 1000 nm.
