Abstract: The present invention relates to modified-metal -particles for corrosion-protection coatings 16 a method for their production and their use anti-corrosive coating compositions and methods for their use. The coating compositions include modified metal particles and a binding agent. The modified metal particles can include zino, aluminum, magnesium, bismuth, tin, nickel, or manganese as well as their mixtures and alloys thereof and have an inorganically-based surface modification in the form of a coating layer capable of imparting cathodic corrosion protection. Suitable surface modifications include a coating layer formed by an inorganic oxide including silicon dioxide, titanium oxide, zirconium oxide, and mixtures thereof.
