摘要： A metallic object, having a metallic substrate of a valve metal or a valve metal alloy inclusive of intermetallic phases, and a thin polyphase oxide coating, is disclosed. The polyphase oxide coating has a metal oxide phase and at least one other organic and/or inorganic phase. The polyphase oxide coating is produced by bringing the metallic substrate into contact with an organic and/or inorganic component to be integrated into the polyphase oxide coating such that the inorganic and/or organic phases are present at or in the direct vicinity of the substrate surface and by simultaneously or subsequently anodically polarizing the substrate material in an electrolytic solution.

摘要： 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.
