Abstract:
A metal substrate with a corrosion-resistant coating produced by means of plasma polymerization, comprising the steps of:smoothing the substrate using mechanical, chemical, and/or electrochemical smoothing, wherein an average mean roughness of the metal substrate of less than 350 nm is obtained; producing an activated surface of the substrate by subjecting the substrate to a reducing plasma at a temperature of less than 200Â° C. and a pressure of 10âˆ’5 to 100 mbar; and depositing a plasma polymer on the substrate from a plasma that contains at least one hydrocarbon or organosilicon compound, optionally containing oxygen, nitrogen, or sulfur, that can be vaporized under the plasma conditions, and which may contain fluorine atoms.
