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.
