Abstract: The present invention relates to the use of oxidic nanoparticles having an average particle size of 2 to 2000 nm in combination with at least one polycationic polymer as corrosion protection for metallic surfaces and also to a method of protecting metallic surfaces from corrosion, comprising the steps of: i) providing a formulation comprising oxidic nanoparticles (a) and at least one polycationic polymer (b) and an application medium, ii) applying the formulation to the metallic surface that is to be protected, and iii) optionally drying and/or heat-treating the surface.
