Abstract
The invention relates to open-pore biocompatible surface layers for implants, which layers are arranged over virgin surfaces of the implants, wherein pores of the open-pore surface layers are connected to form coherent pore networks and the surface layers have a specific internal surface area of ≧0.06 μm/μm2, preferably ≧0.035 μm/μm2 and especially ≧0.025 μm/μm2, measured by image analysis as a 2D-boundary line per unit of surface area in a metallographic microsection at 100× magnification. The invention further relates to methods of producing such surface layers, to implants coated therewith and to possible uses of the surface layers.
