A bioactive surface layer that is particularly suited for medical implants and prostheses. A variable portion of the 0.1 to 50.0 μm thick, porous surface layer includes calcium phosphate phases. The surface layer contains amorphous or nanocrystalline calcium phosphates and the pore density on the surface of the surface layer ranges from 10 4 to 10 8 pores/mm 2 . The ratio of Ca/P over the entire surface layer ranges from 0.5 to 2.0. The surface layer has a high solubility so that it can act as a contributor of calcium phosphate for the formation of bone. |
