An implant (1) in particular an acetabular implant for implantation into a bone has at least in parts a surface structure (2) of raised portions (3) and depressions (4). The depressions (4) have zones coated with a porous coating (5). The raised portions are either not coated at all or are coated such that the coating has a lower layer thickness or a higher abrasion resistance in these portions. In this way an improved abrasion behavior is reached when the implant is inserted into the bone.
