Claim Text:
1. A process for preparing 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, enriched with Ca, P, Si, Na and at least one metal selected from the group consisting of: Ag and Ga, wherein said process consists of the following steps: a) cleaning the metal substrate by immersing the substrate in an ultrasound tray containing acetone for a first period of time of from 3 to 5 minutes and distilled water for a second period of time of from 3 to 5 minutes b) subjecting the metal substrate to an anodic spark deposition (ASD) treatment in an aqueous solution comprising sodium silicate hydrate (Na c) cleaning the metal substrate with water by immersing the metal substrate coming from step b) in distilled water and finally drying the same.
