“…On the molecular level, the physical and chemical properties of the implant surface, e.g. structure, defects, roughness, contamination layer, smface energy and surface charges [5,6], are highly significant in determining the type and degree of surface/biomolecule interactions [7]. One of several factors that detennine the adsorption kinetics of proteins on surfaces is the electrochemical behavior of the titanium oxide [8][9][10].…”

The excellent biocompatibility of titanium and its alloys is intimately related with the properties of the surface in contact with the biological environment, and therefore it is closely connected with the stable, passivating oxide layer that forms on its surface. In the present paper, the oxide layer on the alloy Ti6Al7Nb has been characterized using X-ray photoelectron spectroscopy, scanning Auger microscopy and pH-dependent lateral force microscopy. The alloying elements Al and Nb are incorporated in the oxide layer and detected in their most stable oxidized form, as Al2O3 and Nb2O5. Their distribution in the oxide reflects the underlying alpha-beta microstructure, with enrichment of Al in the alpha- and of Nb in the beta-phase (determined by electron microprobe). Friction measurements (lateral force microscopy) indicate slightly different, pH-dependent, lateral forces above the alpha- and beta-phase structures that point to small local variations in surface charges.
