Titanium-based substrate coatings are required for intra-bone implants, which are used as bioactive implant materials with enhanced osteoconductive properties. The intra-bone implant is obtainable by subjecting the non-porous titanium-based bioinert substrates to mechanical and chemical surface treatments in two steps, first to obtain an alkaline precoat on the titanium substrate, where a porous nanostructured precoat with a specific surface area of at least 80 mma a wetting angle of less than 90 °. In a second step, this precursor layer is exposed in solutions containing calcium and phosphate ions, allowing calcium and phosphate ions to be incorporated into the final substrate layer, optionally their crystalline and / or amorphous deposits. The thickness of the final layer does not exceed the thickness of the initial layer. |
