摘要

The invention relates to a method for coating objects consisting of valve metals or the alloys thereof with a thin barrier layer of the metal and an oxide ceramic layer located thereon, the surface of said oxide ceramic layer being coated with fluoropolymers. The invention is characterised in that said fluoropolymers are introduced, in the form of a solution, into the capillary system of the oxide ceramic layer by means of vacuum impregnation, and are dried once the non-wetting parts of the solution have been removed.
