摘要
A substrate of a metal selected from the group consisting of titanium, tantalum, titanium alloys and tantalum alloys, modified by anodic spark deposition (ASD) on the surface thereof of a microporous and nanoroughened layer of the oxide of the same metal, said layer being enriched with Ca, P, Si, Na, and at least one metal selected from Ag and Ga.;This surface modified metal substrate show excellent osteointegrating properties associated with antibacterial activity. A further advantage resides in that its preparation process does no longer require alkaline etching to promote cellular adhesion.
