The implant has a body comprising a largely biodegradable metallic material e.g. magnesium or a magnesium alloy. The implant has a layer on a portion of a surface of the body of the implant, where the layer contains a hydrogen-binding material i.e. palladium. The layer has a layer thickness of approximately 2 micrometers to approximately 6 micrometers. The implant has another layer comprising parylene and/or magnesium stearate arranged over the former layer on a portion of the surface of the implant body. The layer is applied by a galvanic treatment in an aqueous solution such that the aqueous solution contains a water-soluble conductive salt, potassium dihydrogen phosphate, a chelating agent, optionally citric acid, ethylenediaminetetraacetic acid, tartaric acid, a metal compound containing palladium, a compound from a group comprising palladium-II acetate trimer and tris dipalladium. The aqueous solution for producing the intermediate layer contains ions selected from a group of phosphate ions, potassium ions and calcium ions. An independent claim is also included for a method for manufacturing a degradation-inhibiting layer structure on a surface of an implant body. |
