The present invention relates to a method for producing a metal workpiece for cold forming by applying a lubricant layer with a conversion coating to a metal surface or a pre-coated metal surface, wherein the lubricant layer comprises at least one water soluble, water-containing and It is formed by contact with an aqueous lubricant composition containing water bonds and / or silicates, and organic polymer materials, and / or ionomers, acrylic acids and / or methacrylic acids, epoxides, ethylene, polyamides, propylene, styrenes, urethanes. Monomers, oligomers, co-oligomers, polymers and / or copolymers based on their ester (s) and / or salt (s) are used as organic polymer materials. The invention also relates to corresponding lubricant compositions, lubricant layers formed therefrom, and their use. |
