Zusammenfassung:A coating solution for providing a corrosion resistant coating to a metal surface including: a water soluble silicate; and at least one metal ion (X) selected from those having a valence of less than or equal to +4; wherein said coating solution forms an aqueous silicate-X network such that the silicate remains soluble, and wherein on contact with a metal surface (Y) a coating comprising of silicate-X and Y is formed.
