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 &#x2267;0.06 &#x3bc;m/&#x3bc;m, preferably &#x2267;0.035 &#x3bc;m/&#x3bc;mand especially &#x2267;0.025 &#x3bc;m/&#x3bc;m, measured by image analysis as a 2D-boundary line per unit of surface area in a metallographic microsection at 100&#xd7; magnification. The invention further relates to methods of producing such surface layers, to implants coated therewith and to possible uses of the surface layers.
