An implant and a process of modifying an implant surface, which implant is in particular a hip implant, a tooth implant, a bone screw, fixation pin or a fixation nail (pin-fixation), comprising a metallic base body ( 1 ), which implant has a surface modified by a tantalum or niobium, for the formation of a surface modification ( 4 ) where at least the tissue-friendly metal is alloyed with the surface and constitutes a uniform, diffusion-tight outer zone ( 2 ) on the body ( 1 ), which outer zone ( 2 ) has a higher ductility than the metallic base body ( 1 ) in order to obtain a tissue-friendly implant with increased fatigue strength. |
