Abstract: The invention relates to a bone implant which comprises a magnesium-containing metallic material having a reduced corrosion rate and inorganic bone cement, and to methods and a kit for producing the bone implant. With a method according to the invention, it is possible to obtain a bone implant which comprises inorganic bone cement and a magnesium-containing metallic material with a corrosion-inhibiting coating which contains magnesium-ammonium phosphates. In the method according to the invention, a magnesium-containing metallic material, of which the surface has a magnesium oxide layer and/or a magnesium salt layer, is combined with inorganic bone cement in order to generate a solid composite material that comprises the inorganic bone cement and the magnesium-containing metallic material.

Abstract: The invention relates to methods for producing a partial or complete bioactive coating of an iron and/or zinc based metal implant material with calcium phosphates, a bioactively coated iron and/or zinc based metal implant, which is partially or completely coated with calcium phosphates, and bone implants containing an implant material according to the invention. In order to produce the coating according to the invention, iron and/or zinc based metal implant materials are brought in contact with acidic aqueous solutions, which have a pH value of 6.0 or less and contain calcium phosphates, whereby a calcium phosphate layer is deposited on the surface of the implant materials. The iron and/or zinc based metal implant materials, which are used in methods according to the invention, are materials consisting of base iron alloys or pure iron or materials that contain other substances, which are coated with pure iron, with a base iron alloy and/or with zinc.
