Verfahren zur korrosionsfesten Beschichtung von Metallsubstraten mittels Plasmapolymerisation

The invention relates to a method for corrosion-resistant coating of metal substrates by means of plasma polymerisation, wherein the substrate is subjected to mechanical, chemical and/or electrochemical smoothing in a pre-treatment step and is subsequently exposed to a plasma at a temperature of les...

Beschreibung
Zusammenfassung:	The invention relates to a method for corrosion-resistant coating of metal substrates by means of plasma polymerisation, wherein the substrate is subjected to mechanical, chemical and/or electrochemical smoothing in a pre-treatment step and is subsequently exposed to a plasma at a temperature of less than 200 DEG C and at a pressure of 10 - 100 mbars, whereby in a first step the surface is activated in a reducing plasma and in a second step the polymer is separated from a plasma containing at least one hydrocarbon or silico-organic compound which can be vaporized in plasma conditions, optionally contains oxygen, nitrogen or sulphur and can contain fluorine.
